How to Boost Email Deliverability and Stay Out of Spam

Is your email marketing campaign barely hanging on? Low open rates, missed opportunities, and silent inboxes can feel like the end. But here’s the truth—many marketers face this same challenge when emails aren’t crafted or delivered with the right strategies.

Successful email marketing isn’t just about hitting “send.” There’s a right and wrong way to do email marketing. And, once you know the secrets to getting it right, you can turn things around fast.

In this article, we’ll walk you through the best strategies to revive your campaigns and start seeing real results. Read on to find out more!

Authenticate Your Domain to Build Trust

Email authentication is a straightforward way to make sure your messages reach your audience without raising red flags. Authentication works like a verified badge for email, signaling to internet service providers (ISPs) that your emails are legitimate. If you don’t authenticate, your messages risk being filtered as spam.

To authenticate your domain, consider implementing SPF (Sender Policy Framework) and DKIM (DomainKeys Identified Mail) records. 

SPF verifies that your email comes from an authorized server, while DKIM encrypts part of your email header, ensuring its integrity and authenticity. DMARC (Domain-based Message Authentication, Reporting & Conformance) can also be useful as it helps control who can send emails on your behalf.

ISPs prioritize authenticated emails, so making this small adjustment can significantly improve your deliverability and keep your emails out of the spam folder.

Clean Up Your Email List Regularly

Sending to inactive or outdated addresses can hurt your sender’s reputation and increase the chances of landing in the spam folder. A “clean” email list is key to better engagement and higher deliverability rates. Here’s how you can keep your list fresh and effective:

  • Remove Inactive Subscribers: Regularly purge contacts who haven’t engaged with your emails in six months or more. This improves open rates and boosts your sender’s reputation.
  • Validate New Emails: Use email verification tools to confirm active and valid addresses before they even hit your list.
  • Segment by Engagement: Keep a close eye on who’s opening and clicking. You can also create separate lists for high-engagement subscribers versus those who might need re-engagement campaigns.

Maintaining a clean, engaged list reduces the risk of spam complaints and helps boost your email performance.

Work with Email List Brokers to Reach the Right Audience

Collaborating with an email list broker gives you access to well-curated, accurate lists tailored to your target audience. Unlike owning or purchasing data yourself, mail list brokers connect you with vetted, high-quality lists from top providers. This connection helps ensure that your emails reach those most likely to engage with your message.

Email list brokers are an extension of your marketing team, handling everything from selecting the best list to testing, deploying, and reporting results. They use advanced technology to maintain data quality, spending millions annually cleaning and updating their lists. 

This commitment to accuracy improves deliverability and makes sure your emails land in the right inboxes, giving your campaign the best chance of success.

Avoid Spam Trigger Words and Phrases

Some words or phrases in emails can cause your message to be flagged as spam. These include overused sales terms like “free,” “guarantee,” “act now,” or “limited-time offer.” Spam filters are programmed to detect these phrases because spammers often use them.

Here are a few ways to avoid spam triggers in your emails:

  • Use Natural Language: Write your content as if you’re speaking directly to the reader. Avoid “hard sell” tactics and focus instead on informative, engaging language.
  • Avoid Excessive Punctuation and Symbols: Using too many exclamation marks, dollar signs, or all-caps phrases can make your email look suspicious.
  • Test Your Emails First: Some email marketing tools let you preview your message’s spam score before sending it. Use these to identify any triggers in your content that could affect deliverability.

Avoiding these common pitfalls will help keep your messages out of the spam folder, improve deliverability, and make a better impression on your audience.

Note: How often you send emails and the quality of your content both play a big role in deliverability. Sending too many emails within a short period can overwhelm recipients, leading to unsubscribes or spam reports. 

To Sum It All Up

Achieving high email deliverability is a blend of best practices, from maintaining clean email lists to working with reputable email list brokers and optimizing your content. When done right, email marketing can yield impressive returns without hitting roadblocks. By focusing on the details, like authentication, list hygiene, and engaging content, you’ll start seeing more opens, clicks, and conversions from your campaigns.
