Every sales or marketing professional knows the frustration of crafting a perfect outreach email, only to have it languish in the spam folder. This isn\u2019t a rare occurrence \u2013 in fact, 16% of marketing emails fail to reach the inbox at all, with around 10.5% getting diverted to spam and another 6% bouncing back (Improve Email Deliverability - Gmail and Outlook\u2019s 2024 Guidelines<\/a>). When your message ends up buried among unsolicited emails, your outreach campaign\u2019s effectiveness plummets. Potential leads might never even see your offer, wasting the effort put into content and design.<\/p>\n\n\n\n

For businesses, email deliverability is not just a technical nicety; it\u2019s a cornerstone of successful communication. Email remains one of the highest ROI marketing channels (about $36 return for every $1 spent) (Improve Email Deliverability with SPF, DKIM, & DMARC<\/a>), but that ROI is only realized if your emails actually land in recipients\u2019 inboxes. If your sales pitch or newsletter goes unseen, it can\u2019t generate replies, conversions, or revenue. Moreover, repeated spam filtering can hurt your brand\u2019s credibility \u2013 recipients may start to associate your domain with untrustworthy senders. As one email expert bluntly put it, \u201cDeliverability is the cornerstone of cold email outreach... You could have the best email copy in the world, but if no one is seeing it, it\u2019s useless.\u201d (How Smartlead Transformed Bharatt Arorah\u2019s Cold Email Lead Generation<\/a>) In this blog, we\u2019ll explore why emails get flagged as spam and share proven strategies to avoid spam filters, build sender trust, and ensure your emails reliably hit the inbox.<\/p>\n\n\n\n

Why Emails Get Flagged as Spam<\/strong><\/h2>\n\n\n\n

Before diving into solutions, it\u2019s important to understand what triggers spam filters. Modern email providers use sophisticated algorithms to protect users from junk or malicious messages. Unfortunately, legitimate senders can get caught in these nets due to various factors. Common reasons your emails might be flagged as spam include:<\/p>\n\n\n\n

Sending Too Many Emails Too Quickly<\/strong> \u2013 A sudden spike in email volume is a red flag. If you blast out thousands of emails at once (especially from a new or cold IP\/domain), it \u201clooks like you\u2019re spamming\u201d and ISPs may throttle or junk them (13 most common email deliverability issues and how to solve them<\/a>). Gradual sending and \u201cwarming up\u201d your sending IP or domain is crucial to avoid triggering volume-based filters.<\/p>\n\n\n\n

Poor Sender Reputation<\/strong> \u2013 ISPs assign your domain and IP a sender reputation score. If you have a history of low engagement, high bounce rates, or spam complaints, your reputation suffers. A blacklisted or low-reputation domain will find its emails automatically shunted to spam or blocked (Top 10 Strategies to Boost Your Email Deliverability Rates<\/a>). This can happen if your address was used for spam in the past or if you frequently send to unengaged recipients.<\/p>\n\n\n\n

Missing Authentication (SPF, DKIM, DMARC)<\/strong> \u2013 Failing to configure email authentication records can make your messages look suspicious. Without proper SPF or DKIM to verify that an email is really from your domain, providers can\u2019t trust the source. Lack of authentication makes it easier for spam filters to flag your emails as potentially spoofed or phishy. (We\u2019ll discuss authentication in more detail later.)<\/p>\n\n\n\n

Spam-Triggering Content<\/strong> \u2013 The content of your email itself can set off filters. Certain \u201cspammy\u201d keywords (e.g. \u201cFREE!!!\u201d, \u201cBuy now\u201d), excessive ALL CAPS, too many exclamation points, or a text-to-image ratio that\u2019s heavily image-based can all hurt deliverability. Even an innocuous phrase can raise suspicion if it\u2019s commonly used in spam. Likewise, misleading subject lines or lack of relevant text (e.g. an email that is just one big image) may get flagged by content-scoring systems.<\/p>\n\n\n\n

Unverified or Outdated Email Lists<\/strong> \u2013 Sending to a poor-quality list will tank your deliverability. Messages that bounce because the address is invalid, or (worse) hit spam traps, tell providers you\u2019re not maintaining your list. High bounce rates are interpreted as negligence or spamming, dragging your future emails to spam. Using purchased lists or scraping emails can be especially dangerous, as they often contain bad addresses or recipients who never agreed to hear from you.<\/p>\n\n\n\n

Lack of Permission & Unsubscribe Option<\/strong> \u2013 If recipients never explicitly opted into your emails, they\u2019re more likely to mark you as spam out of annoyance. And if your email doesn\u2019t include a clear unsubscribe link, people may hit the \u201cReport Spam\u201d button as their way to stop emails. Not only is an unsubscribe mechanism required by laws like CAN-SPAM, it\u2019s also a safety valve for recipients; not having one raises spam suspicions and can prompt ISPs to penalize your emails.<\/p>\n\n\n\n

Even when you think you\u2019re following all the rules, issues can sneak up. Real-world example: iClientCare, a B2B cold email agency, initially did everything \u201cby the book\u201d \u2013 they set up DNS records properly and even used techniques like spintax (content variation) to personalize emails. Yet, they found that 40\u201350% of their emails were still landing in spam, severely hurting their campaign performance (How iClientCare Brings 95% Positive Reply Rates for Their Clients<\/a>). The problem was so bad with one of their email tools that nearly half their outreach never reached prospects\u2019 inboxes. This experience forced them to adjust their strategy and seek better tools to fix their deliverability. The takeaway: understanding and addressing these common pitfalls is key, because even a well-crafted campaign can fail if underlying deliverability factors are not managed.<\/p>\n\n\n\n

How to Avoid Spam Filters<\/strong><\/h2>\n\n\n\n

Knowing why emails get caught in spam is half the battle. The other half is proactively implementing best practices to avoid those filters altogether. Here are concrete strategies to ensure your messages appear more human, trustworthy, and spam-filter-friendly:<\/p>\n\n\n\n

Throttling & Human-Like Sending Patterns<\/strong><\/h3>\n\n\n\n

One of the most effective tactics is to send emails in a human-like cadence<\/strong> rather than blasting them out in one go. ISPs notice when a sender behaves like a spambot (e.g. firing off 10,000 emails in a minute). To prevent this, use throttling features in your email automation tool or send in smaller batches. Gradually ramp up your sending volume especially if you\u2019re using a new domain or IP \u2013 a process known as \u201cwarming up.\u201d This slower, steady approach helps you fly under the radar of volume-based spam triggers.<\/p>\n\n\n\n

Many modern platforms can automate this. For instance, some cold email tools offer automated warm-up modes that send a trickle of emails initially and build up over days or weeks, which trains ISPs to see you as a legitimate sender with consistent patterns. This mimicry of natural sending (as if you were manually emailing a few people at a time) dramatically lowers the chance of being flagged. Real-world data backs this up \u2013 one case study showed that simply adjusting email sending frequency to more human-like rates led to a 93% improvement in deliverability for bulk campaigns. That same strategy also yielded a 178% increase in website visits from those emails, since far more messages made it to the Primary inbox instead of spam. The lesson: don\u2019t dump emails in one blast. Drip them out, randomize send times if possible, and let your automation tool\u2019s throttling setting be your friend.<\/p>\n\n\n\n

Content Optimization (Writing Non-Spammy Emails)<\/strong><\/h3>\n\n\n\n

How you write your emails plays a big role in deliverability. While there\u2019s no secret formula to guarantee an email passes all filters, you can definitely avoid the known pitfalls:<\/p>\n\n\n\n

Choose Words Carefully<\/strong><\/h4>\n\n\n\n

Steer clear of the classic spam trigger words and phrases. For example, words like \u201c$$$,\u201d \u201cwinner,\u201d \u201cfree gift,\u201d \u201cthis is not spam,\u201d or \u201curgent reply\u201d can raise red flags. Also, avoid excessive punctuation!!! or ALL CAPS SUBJECT LINES \u2013 these are tactics spammers use to grab attention and filters know it. Instead, write clear, truthful subject lines that align with the email\u2019s content. A good rule of thumb is to sound like one colleague emailing another, rather than a flashy advertisement.<\/p>\n\n\n\n

Provide Value and Personalization<\/strong><\/h4>\n\n\n\n

Spam filters increasingly use engagement metrics (like reply rates and reading time) as signals. Emails that are relevant to the recipient are more likely to be engaged with, and thus more likely to avoid spam. So, personalize your emails \u2013 use the recipient\u2019s name, reference their business or pain point, and make the content useful to them. A personalized, value-driven email not only avoids sounding like spam, but also encourages replies (which can improve your sender reputation).<\/p>\n\n\n\n

Proper Formatting<\/strong><\/h4>\n\n\n\n

Compose emails with a balanced text-to-image ratio. A message that\u2019s just one big image or a slew of links can look suspect. It\u2019s usually best to have a mostly text email with maybe one small image or logo, and a couple of relevant links at most. Always include some plain text (spam filters can\u2019t read images, so they rely on text). Additionally, ensure your HTML is clean \u2013 broken HTML code or weird formatting can sometimes trigger content filters. Most major email marketing tools provide templates that are coded correctly, so leverage those. And always include a polite email signature with your name, company, and contact info \u2013 it signals a real person behind the email.<\/p>\n\n\n\n

Test Before You Send<\/strong><\/h4>\n\n\n\n

Consider using spam-checker tools (many email platforms have these built-in) to scan your email content for potential triggers. They\u2019ll flag words or formatting issues that might cause problems. You can also send a test email to yourself (at various email providers like Gmail, Outlook, Yahoo) to see if it lands in spam or if any warnings appear. Adjust the content if needed based on these dry runs.<\/p>\n\n\n\n

List Hygiene & Email Verification<\/strong><\/h3>\n\n\n\n

Your email list\u2019s quality can make or break deliverability. Maintaining pristine list hygiene means regularly pruning out bad addresses and focusing only on engaged recipients. Start by using email verification services (such as Kickbox, ZeroBounce, NeverBounce, etc.) to verify addresses before you send. These services check if an email address is valid and can receive mail. By removing invalid addresses, you prevent bounces from ever occurring, which in turn protects your sender reputation (How Email Verification Helps Avoid the Spam Folder<\/a>). Remember, high bounce rates signal to ISPs that you might be a spammer with an old or purchased list \u2013 not a good look.<\/p>\n\n\n\n

In addition to scrubbing for invalids, watch for inactive subscribers. If someone hasn\u2019t opened or clicked your emails in, say, 6-12 months, consider a re-engagement campaign or removing them from regular sends. Sending continually to a large cohort of unresponsive contacts can drag down your overall engagement rates (open\/reply percentages), which some algorithms interpret as a sign of low-value or spammy content. It\u2019s better to have a smaller list of engaged readers than a huge list that includes many ghosts.<\/p>\n\n\n\n

Implementing a double opt-in for new subscribers is another best practice for list quality. With double opt-in, a new subscriber must click a confirmation link in their email to verify they indeed want to subscribe. This extra step ensures the address is valid and that the person is genuinely interested \u2013 reducing typos and fake sign-ups. It sets you up with a cleaner list from the start, which means fewer bounces and complaints later.<\/p>\n\n\n\n

By keeping your list clean, you not only avoid spam folder issues, but you also save resources and improve ROI. You\u2019re not paying to send emails to addresses that go nowhere, and you\u2019re focusing your efforts on an audience that actually wants to hear from you. One marketing study put it plainly: sending to unverified, bad emails wastes time and money and can even get you blacklisted by providers. In short, clean that list like your business depends on it \u2013 because it might!<\/p>\n\n\n\n

Compliance & Reputation Management<\/strong><\/h3>\n\n\n\n

Staying on the right side of anti-spam laws and ISP guidelines is critical for building a long-term trustworthy sender reputation. Compliance isn\u2019t just a legal box to check; it directly impacts whether inbox providers view you as a legitimate sender or a potential spammer.<\/p>\n\n\n\n

First, make sure every email you send includes the necessary footer information: your business address and a clearly visible unsubscribe link. Reputable email services will often insert the unsubscribe link automatically (for example, Mailchimp\u2019s templates include an unsubscribe link by default to comply with CAN-SPAM (About Unsubscribes | Mailchimp<\/a>)). If you\u2019re coding your own emails, don\u2019t skip this. Beyond legality, giving recipients an easy opt-out shows you respect their choice \u2013 and it will reduce the likelihood they flag your email as spam out of frustration. Platforms like Mailchimp actually require an unsubscribe in every campaign and will enforce it to protect their sending reputation and yours.<\/p>\n\n\n\n

Next, obtain proper consent for your emails. This is not only a best practice, but a requirement in many jurisdictions. The GDPR in Europe, for instance, mandates explicit consent for marketing emails \u2013 sending bulk unsolicited emails to EU residents can land you in legal hot water (and get your domain flagged). The CAN-SPAM Act in the U.S. is a bit less strict about opt-in, but it still requires honoring opt-outs and avoiding deceptive subject lines, among other things. Bottom line: permission-based emailing isn\u2019t just ethical, it keeps your messages welcome in recipients\u2019 inboxes. When people actually want your emails, they engage more and complain less, which boosts your sender reputation organically.<\/p>\n\n\n\n

Now let\u2019s talk about domain authentication protocols \u2013 SPF, DKIM, and DMARC \u2013 which are vital for establishing trust. These might sound technical, but they are essentially ways to prove to mail servers that \u201cYes, this email is legitimately from yourdomain.com.\u201d Setting up these DNS records is a one-time task that pays permanent dividends in deliverability:<\/p>\n\n\n\n

SPF (Sender Policy Framework)<\/strong><\/h4>\n\n\n\n

This is a DNS record that specifies which mail servers are allowed to send email on behalf of your domain. It\u2019s like a bouncer with a guest list \u2013 when an email from your domain arrives, the receiving server checks the SPF record to see if the sending server\u2019s IP is on the list. If yes, you pass this check; if not, the email might be viewed as forged or suspect. Make sure all the services you use to send email (your mail server, marketing platform, CRM, etc.) are included in your SPF record.<\/p>\n\n\n\n

DKIM (DomainKeys Identified Mail)<\/strong><\/h4>\n\n\n\n

DKIM adds a digital signature to your emails that receivers can verify by looking up a public key in your DNS records. Think of it as a wax seal on a letter \u2013 it proves the email hasn\u2019t been tampered with and indeed comes from the domain it claims to. When you enable DKIM signing (often done in your email provider\u2019s settings and by adding a DNS record), your emails get that cryptographic signature in the headers. Receiving mail servers will decrypt that signature using your public key and, if it matches, they know the email is authentic and untampered. This greatly increases the likelihood of your email being trusted and delivered.<\/p>\n\n\n\n

DMARC (Domain-based Message Authentication, Reporting & Conformance)<\/strong><\/h4>\n\n\n\n

DMARC builds on SPF and DKIM. It\u2019s a policy you publish that tells receivers what to do if an email fails SPF\/DKIM checks \u2013 for example, you can start with \u201cp=none\u201d (do nothing special, just collect reports), then move to \u201cp=quarantine\u201d (spam-folder the failures) or \u201cp=reject\u201d (outright reject failures) as you gain confidence. DMARC also provides a reporting mechanism: you can get reports on who\u2019s sending emails purporting to be from your domain and whether they pass SPF\/DKIM. Implementing DMARC with a quarantine\/reject policy, once your SPF\/DKIM are solid, helps prevent spoofers from using your domain and further solidifies to ISPs that emails from your domain are well-managed and authentic (IGN Email Verification Case Study | Kickbox<\/a>).<\/p>\n\n\n\n

Properly configuring SPF, DKIM, and DMARC can dramatically improve your email deliverability and protect your brand from being spoofed. In one real-world case, a company discovered that their email authentication was not optimally set up, which was undermining their sender reputation. After a thorough audit, they upgraded their SPF, DKIM, and DMARC settings, and the result was a clear improvement in deliverability rates and security. In short, authentication protocols help you build an email sending reputation that ISPs trust. They are now considered \u201cfoundational parts of any successful email program\u201d, not just technical extras.<\/p>\n\n\n\n

Lastly, keep an eye on your sender reputation metrics. Tools like Google Postmaster Tools, Microsoft SNDS, or third-party services (SenderScore by Validity, for example) can give you insight into how ISPs view your domain. If you see red flags there \u2013 high spam complaint rates, hitting spam traps, etc. \u2013 take corrective action immediately (cleaning your list, slowing down sends, adjusting content). Proactively monitoring these metrics is part of good reputation management. It\u2019s much easier to maintain a good reputation than to repair a damaged one.<\/p>\n\n\n\n

Case Study: How Best Practices Improved Deliverability<\/strong><\/h3>\n\n\n\n

To see these strategies in action, let\u2019s look at a real-life business that turned around its email performance by implementing deliverability best practices. IGN, a large media company in the entertainment and gaming industry, faced severe email deliverability challenges. They had a rapidly growing subscriber base, but alongside that growth came increasing hard bounce rates and plummeting engagement \u2013 a clear sign that many emails weren\u2019t reaching the inbox. An investigation revealed that while IGN\u2019s content was popular, their sending domain wasn\u2019t fully trusted: essential authentication protocols (SPF\/DKIM\/DMARC) were not properly configured, and their mailing lists contained a lot of poor-quality addresses. These issues caused even interested subscribers to miss communications, as messages were either blocked or spam-foldered.<\/p>\n\n\n\n

IGN tackled the problem head-on by partnering with an email deliverability service and executing a multi-pronged fix. They performed a comprehensive email list cleanup, using verification tools to remove bad emails and ensure they only send to valid, active subscribers. At the same time, they fixed their technical setup \u2013 implementing SPF, DKIM, and DMARC properly across all their sending domains to authenticate their emails and prevent spoofing. With a healthier list and authenticated domain, they also refined their sending strategy (better segmentation and sending times) to re-engage their audience. The outcome was dramatic: IGN saw a 56% increase in open rates and a 30% increase in click-through rates after these changes. In other words, by practicing what we\u2019ve outlined \u2013 list hygiene, authentication, and sending strategies \u2013 they significantly boosted the portion of their audience they were actually reaching, leading to a big uptick in engagement with their content. This case underscores that avoiding spam filters isn\u2019t just about technical tweaks; it translates directly into more eyes on your emails and more interaction with your business.<\/p>\n\n\n\n

How Automation Helps<\/strong><\/h2>\n\n\n\n

Managing all of the above might sound daunting \u2013 especially if you\u2019re trying to do it manually for large campaigns. This is where email automation tools and platforms become invaluable. Modern email service providers (ESPs) and sales automation tools come packed with features designed to enhance deliverability while keeping you compliant. They essentially act as your co-pilot, handling the nitty-gritty so you can focus on content and strategy. Here\u2019s how the right tools can help:<\/p>\n\n\n\n

Built-in Throttling and Scheduling<\/strong><\/h3>\n\n\n\n

Most reputable email platforms (e.g. Mailchimp, HubSpot, SendGrid, Outreach, Salesloft, etc.) allow you to schedule sends or automatically throttle the send rate. For instance, you can set a campaign to send in batches of X emails per hour, or use features like Mailchimp\u2019s \u201cSend Time Optimization\u201d or HubSpot\u2019s \u201cSeventh Sense\u201d integration that send emails at the times each contact is most likely to engage. Such features prevent the \u201ctoo many emails, too fast\u201d problem by pacing your campaigns intelligently. Some tools will even detect when you\u2019re emailing a large new list and recommend an IP warming process. As noted earlier, one solution achieved a huge deliverability boost by matching human sending patterns \u2013 these kinds of send schedulers make that feasible at scale.<\/p>\n\n\n\n

Content and Spam Checks<\/strong><\/h3>\n\n\n\n

Automation platforms often include spam filter testing and content analysis. They\u2019ll flag words or phrases that are problematic, check if your email is missing an unsubscribe link or a physical address (and add it if needed), and even evaluate the HTML for issues. For example, services like SendGrid and Mailchimp have built-in checkers and will warn you if your email content might trigger filters. This guidance helps you fix problems before you hit Send. Additionally, many tools support A\/B testing for subject lines and content. You can experiment and see which versions get better engagement \u2013 indirectly improving deliverability by choosing the content that readers respond to best.<\/p>\n\n\n\n

Automatic List Management<\/strong><\/h3>\n\n\n\n

Good email platforms take list hygiene partly into their own hands. They will automatically remove hard bounces from your active list (so you don\u2019t accidentally keep sending to an address that bounced once). They also handle unsubscribes instantly \u2013 as soon as someone opts out, the platform ensures no further emails go to them. Some tools like HubSpot can even track engagement and help you create suppression lists of chronically unengaged contacts (so you stop emailing people who never open). Mailchimp\u2019s \u201cOmnivore\u201d abuse-prevention system goes a step further: it scans any new list you import and proactively suspends sends if the list looks risky (high predicted bounce or spam complaint rate) (About Omnivore | Mailchimp<\/a>) (About Omnivore | Mailchimp<\/a>). This might feel like a roadblock if you\u2019re eager to send, but it\u2019s actually protecting you \u2013 and all users \u2013 from getting blacklisted due to a bad list. In short, automation tools have built-in safeguards to keep your list healthy and your sender reputation intact, even as you scale up.<\/p>\n\n\n\n

Compliance Tools and Guidance<\/strong><\/h3>\n\n\n\n

As mentioned, most platforms force compliance elements like unsubscribe links. They\u2019ll often have templates that include the required CAN-SPAM details by default. Beyond that, some provide GDPR-friendly features (like tracking consent, managing customer data requests, etc.). For example, an email service might allow you to segment EU customers and ensure you have a record of their opt-in. Automation also makes it easy to honor opt-out and preference requests \u2013 if a user wants to reduce frequency or change topics, a good system can handle that. All these features mean you are less likely to run afoul of spam regulations or annoy recipients, which in turn preserves trust and deliverability.<\/p>\n\n\n\n

Deliverability Analytics and Support<\/strong><\/h3>\n\n\n\n

The top-tier email providers often have specialized tools or even personnel focused on deliverability. For instance, SendGrid (now part of Twilio) offers deliverability analytics dashboards, ISP outreach, and even coaching services for senders (Email Delivery | SendGrid<\/a>). They\u2019ll tell you if they see issues with your sending and advise on how to improve. Some services monitor blacklists and will alert you if your domain or IP lands on one. This kind of insight is incredibly useful \u2013 it\u2019s like having a security system that alerts you to potential break-ins (in this case, deliverability troubles) so you can address them quickly. Moreover, large ESPs maintain relationships with inbox providers (Google, Microsoft, etc.) and advocate for their customers\u2019 ability to reach the inbox, as long as those customers follow best practices. By using a reputable platform, you\u2019re indirectly benefiting from their industry partnerships and whitehat reputation.<\/p>\n\n\n\n

Advanced Sending Features<\/strong><\/h3>\n\n\n\n

Some automation platforms optimize how your emails are sent in technical terms. For example, they might use multiple sending IP addresses and rotate your emails through them if you\u2019re sending bulk, to distribute load (and risk). They might automatically shift to a different IP if one gets temporarily throttled. Many services also allow dedicated IP addresses for senders who do large volumes \u2013 this can be useful to isolate and control your sender reputation (though it requires a warm-up period). Additionally, the ability to segment and personalize at scale (which automation excels at) means you can send more relevant emails to smaller groups rather than one generic email to everybody. Sending 10 targeted campaigns to 1,000 people each will generally fare better than sending 1 blast to 10,000, from a deliverability standpoint.<\/p>\n\n\n\n

To illustrate the impact of the right automation tool, let\u2019s revisit the earlier example of iClientCare, the agency that struggled with spam. They decided to switch to an automation platform (Manyreach) that prioritized deliverability. This new tool offered easier DNS setup, automated warm-ups, and overall better handling of sends. The result? iClientCare\u2019s campaigns went from 40-50% landing in spam to the vast majority hitting inboxes. With far more prospects actually seeing their messages, their outreach performance skyrocketed \u2013 they started booking 15+ sales calls per week and achieved reply rates as high as 27% (with 95% of replies being positive) on behalf of their clients. According to their founder, the \u201cunmatched deliverability\u201d of the new platform was key to these results. This success story shows that investing in a good email automation service isn\u2019t just about convenience \u2013 it directly affects your bottom line by making sure your emails land where they\u2019re supposed to. The tool handled the heavy lifting of compliance and delivery optimization, allowing the agency to focus on crafting great campaigns and scaling their business confidently.<\/p>\n\n\n\n

In summary, automation, when used wisely, amplifies your ability to reach inboxes. It enforces best practices, provides you with data and safeguards, and optimizes the sending process in ways that would be hard to do manually. Whether you\u2019re a small business or an enterprise, leveraging these platforms can give you a significant advantage in the battle for the inbox.<\/p>\n\n\n\n

The Business Impact of Better Deliverability<\/strong><\/h2>\n\n\n\n

It\u2019s clear by now that improving deliverability isn\u2019t just an IT nicety \u2013 it has tangible business benefits. Let\u2019s highlight the key impacts that companies see when they get their emails out of spam and into the inbox:<\/p>\n\n\n\n

Higher Open and Response Rates<\/strong><\/h3>\n\n\n\n

This one\u2019s obvious but fundamental \u2013 if more emails reach the inbox, more people will open them. Even a small percentage increase in inbox placement can translate to a big jump in opens. For example, when one company improved their delivery rate and email health, they saw a 21% increase in total emails opened and 28% more clicks on those emails (Case Study: 21% Increase in Email Opens, 28% Increase in Email Clicks and a 29% Increase in New Sales-Qualified Leads with Marketing Automation<\/a>). Those extra opens and clicks are opportunities \u2013 more prospects reading your message, more customers engaging with your content. In sales outreach, higher deliverability means your reps get more replies to work with. In marketing, it means more traffic to your website or landing pages. It\u2019s the top of the funnel getting bigger. And as we saw with IGN and iClientCare, in some cases fixing deliverability issues can dramatically multiply your engagement metrics (IGN\u2019s open rates jumped by over 50% after their improvements). All of this can be traced back to the simple fact: you can\u2019t engage an email that you never received. Boost deliverability, and you boost all the downstream metrics.<\/p>\n\n\n\n

Improved Brand Reputation and Credibility<\/strong><\/h3>\n\n\n\n

Think about the signals you send with your email behavior. If your emails frequently land in spam, recipients who do find them may start to doubt your legitimacy. They might think, \u201cOur email system thinks this is spam, maybe this company isn\u2019t trustworthy.\u201d On the flip side, when your emails consistently land front-and-center in the inbox, it subconsciously tells people that your communications are legit and important enough to make it past the filters. By adhering to best practices, you also reduce negative experiences (like people getting unsolicited emails or too many emails). This preserves your brand\u2019s goodwill. As noted earlier, bombarding users with unwanted or irrelevant emails can erode trust and damage loyalty. Conversely, good deliverability often goes hand-in-hand with sending relevant content to people who asked for it, which strengthens customer trust. They see you respect their inbox, so they\u2019re more likely to view your brand positively and engage with future emails rather than tuning you out. Also, a solid sender reputation means if you ever do have an important alert (product recall, security notification, etc.), you can reliably reach your customers \u2013 protecting your brand by being able to communicate in critical moments.<\/p>\n\n\n\n

Increased Conversions and Sales<\/strong><\/h3>\n\n\n\n

Better deliverability leads to better conversion outcomes down the line. If you\u2019re a marketer, more opens and clicks mean more people entering your sales funnel or making purchases. If you\u2019re doing cold sales emails, more replies mean more deals being put on the table. The math of email ROI (return on investment) starts to really improve as deliverability increases. Recall that email has an average ROI of 36:1 \u2013 that assumes your emails get delivered properly. When you solve inbox placement issues, you are essentially unlocking revenue potential that was previously lost. We saw earlier that one change (sending at human-like frequency) produced 178% more website page visits from email. More website visits from emails likely means more sign-ups or sales occurring. Similarly, the agency that fixed their deliverability started booking significantly more sales calls and deals for their clients \u2013 a direct impact on revenue. Over time, the compounding effect of higher conversion rates can be huge. If each of your email campaigns or sales cadences performs, say, 15% better because it reaches more people, that could translate into 15% more revenue from email as a channel. Scale that across a year\u2019s worth of campaigns, and it\u2019s an easy justification for investing in deliverability.<\/p>\n\n\n\n

In addition to these points, good deliverability helps with operational efficiency \u2013 your team isn\u2019t firefighting email issues or chasing false leads from unverified contacts. It can also protect you from costs of non-compliance (no fines or legal troubles because you\u2019re following the rules). And let\u2019s not forget, a message in the inbox has a chance to be forwarded or shared, whereas a message in spam is essentially dead on arrival. By landing in the inbox, you keep the door open for referrals and virality as well.<\/p>\n\n\n\n

Simply put, when your emails land in the inbox, your business lands more opportunities. You reach more of your audience, maintain a positive brand image, and drive more actions that lead to sales or other goals. It\u2019s the foundation upon which successful email marketing and outreach is built.<\/p>\n\n\n\n

The battle for the inbox can be challenging, but it\u2019s one worth fighting \u2013 and one you can win by applying the right best practices. We\u2019ve learned that spam filters, while useful for stopping bad actors, can inadvertently snare well-intentioned senders. To recap the key takeaways for ensuring your emails avoid spam filters and build trust with recipients:<\/p>\n\n\n\n

Monitor and improve your sending habits:<\/strong> Don\u2019t send too fast or to too many people at once. Warm up new domains\/IPs gradually and aim for consistent, human-like sending patterns. Use throttling features and send-time optimization to your advantage.<\/p>\n\n\n\n

Craft clean, sincere content:<\/strong> Avoid known spam trigger words and gimmicky formatting. Personalize your emails and focus on providing value to the reader. A\/B test your subject lines and content to find what resonates (and what keeps you out of spam).<\/p>\n\n\n\n

Keep your lists healthy:<\/strong> Regularly verify and clean your email lists to eliminate bounces and spam traps. Remove or re-engage dormant subscribers instead of blasting everyone. Build your list through confirmed opt-ins so you start with quality contacts from day one.<\/p>\n\n\n\n

Authenticate and comply:<\/strong> Set up SPF, DKIM, and DMARC for your sending domains \u2013 this is non-negotiable for building trust with ISPs. Always include an unsubscribe link and honor removals. Ensure you have permission (consent) for the people you email, sticking to laws like CAN-SPAM and GDPR.<\/p>\n\n\n\n

Leverage automation tools:<\/strong> Don\u2019t go it alone. Utilize reputable email service providers or outreach platforms that have built-in deliverability safeguards \u2013 things like automatic unsubscribe handling, bounce management, content checks, and sending limit controls. These tools not only save you time, but actively boost your chances of reaching the inbox.<\/p>\n\n\n\n

Improving email deliverability is not a one-time task but an ongoing part of your email strategy. The good news is that each step you take to appease the spam filters is usually a step that makes your emails more reader-friendly too. When you send considerate, wanted emails to verified addresses, everybody wins: your audience gets content they care about, and you get the results you care about.<\/p>\n\n\n\n

As an actionable next step, consider doing a quick audit of your current email setup. Check your domain\u2019s SPF\/DKIM records (if you\u2019re not sure, many online tools can validate them for you). Review your last campaign\u2019s stats for bounces and complaints \u2013 if those numbers are high, prioritize list cleaning and maybe segment out the less engaged folks for a lighter touch. Look at your email content and ask, \u201cDoes anything here look like it could be spammy to a filter (or to a recipient)?\u201d \u2013 if yes, tweak it. And if you haven\u2019t already, explore the features of your email platform or consider upgrading to one that champions deliverability.<\/p>\n\n\n\n

By following the best practices outlined in this guide, you\u2019ll be well on your way to keeping your emails out of the dreaded spam folder. Remember, the goal isn\u2019t just to send emails \u2013 it\u2019s to have them seen and acted upon. With a bit of upfront effort and the right habits, you can ensure your emails always land in the inbox and build lasting trust with your audience.
