In the busy world of digital marketing, crafting the perfect email can feel like an art form—but even the best emails are useless if they don’t reach their audience. For marketing managers juggling multiple tasks, ensuring emails actually land in inboxes is essential to every campaign’s success. This blog covers the top email deliverability tips to help you get your messages in front of the people who need to see them.

Key Takeaways

• Verify Your Domain and Clean Your List: Trustworthy domains and updated lists improve deliverability.

• Optimize Content and Avoid Spam Triggers: Create professional, engaging emails that appeal to recipients and avoid spam filters.

• Choose a Reliable ESP and Maintain Sender Reputation: A strong sender reputation and reputable ESP contribute to effective email deliverability.

What is Email Deliverability and Why Does it Matter?

Email deliverability refers to the ability of an email to land in the recipient's inbox rather than the spam folder. Achieving high deliverability rates is crucial for anyone hoping to make an impact through email marketing. The goal is to ensure that the emails you send reach their intended recipients, optimizing both open and engagement rates.

Improving email deliverability means improving campaign effectiveness without increasing your workload—ideal for marketers focused on efficient and scalable solutions.

1. Use a Verified Email Domain

One of the foundational steps to improving email deliverability is using a verified email domain. Sending emails from your verified domain establishes credibility with inbox providers and reduces the risk of your messages being marked as spam.

• How to Verify Your Domain: In your email marketing platform, follow the steps to authenticate your domain by setting up DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework). Platforms like Google, Yahoo, and Outlook check these records to confirm your emails come from a trustworthy source.

• Benefits: Increased deliverability and brand credibility.

Using a verified domain ensures your emails are seen as legitimate, which is essential in gaining the trust of both email servers and recipients.

2. Clean Your Email List Regularly

Keeping an up-to-date, accurate email list is one of the best practices for maintaining deliverability. Having too many invalid or inactive email addresses on your list can lead to high bounce rates, which damages your sender reputation over time.

• How to Clean Your List:

  • Remove email addresses that haven’t engaged in a set timeframe, such as six months.

  • Identify and delete hard bounces (emails that permanently fail to deliver).

  • Use list-cleaning services, such as ZeroBounce or NeverBounce, to automate the process.

• Benefits: By focusing on engaged recipients, you’ll increase your open rates and improve overall deliverability.

A clean list is one of the simplest and most effective ways to ensure that your emails consistently reach active recipients.

3. Optimize Your Subject Lines and Content

Creating relevant, engaging content is essential for good deliverability. Many email providers scan subject lines and body content to determine whether an email is spam. Avoid using overly promotional language and make sure your content is helpful, engaging, and to the point.

• Best Practices for Subject Lines:

  • Avoid words like “free,” “buy now,” and excessive punctuation, as they trigger spam filters.

  • Keep subject lines short and concise to increase open rates, especially for mobile users.

  • Test different subject lines to see what resonates best with your audience.

• Body Content Tips:

  • Balance text with visuals to create visually appealing emails without overwhelming your audience.

  • Include clear calls-to-action (CTAs) to make your intent known.

  • Use personalizations, like first names, to make the email feel tailored to each recipient.

With content and subject lines that appeal to readers, your emails are more likely to avoid the spam folder and receive higher engagement.

4. Avoid Using Spam Trigger Words and Symbols

Certain words and symbols act as red flags to spam filters. By understanding which words and symbols to avoid, you can significantly improve your chances of bypassing spam filters.

• Common Spam Triggers:

  • Words like “discount,” “deal,” and “clearance” can often be flagged.

  • Excessive use of symbols like “$,” “!!!,” and ALL CAPS also triggers spam filters.

• Alternative Approach:

  • Instead of phrases like “Act Now!” try “Explore Our Latest Offers.”

  • Limit symbols and exclamation points to give your email a professional, trustworthy tone.

By crafting email copy that is conversational yet informative, you can avoid being flagged as spam and improve the chances of your emails reaching the inbox.

5. Implement Double Opt-In for New Subscribers

Using a double opt-in process is an effective way to ensure your email list is filled with recipients genuinely interested in receiving your content. This process requires new subscribers to confirm their email addresses, typically by clicking a link sent to their inbox.

• How to Set Up Double Opt-In: Most email marketing platforms, such as Mailchimp or Constant Contact, offer the option to send a confirmation email automatically after a new sign-up.

• Advantages:

  • Builds a more engaged email list.

  • Reduces the chance of spam complaints and hard bounces.

  • Ensures you’re sending content to people who genuinely want it.

Double opt-in helps build a high-quality list, which can positively impact deliverability by reducing the number of unsubscribes and spam reports.

6. Monitor and Maintain a Good Sender Reputation

Sender reputation plays a significant role in deliverability. Internet Service Providers (ISPs) assess your sender reputation based on factors such as your bounce rate, open rate, and spam complaints. Keeping a close eye on these metrics can help you maintain a positive reputation.

• Tips to Monitor Reputation:

  • Use tools like SenderScore or Postmaster by Google to track your sender reputation.

  • Avoid excessive sending rates that can appear spammy to ISPs.

• Benefits of Good Reputation: Higher sender reputation means greater deliverability and fewer chances of landing in the spam folder.

Maintaining a positive sender reputation requires consistent monitoring, but it can make a significant difference in the success of your email campaigns.

7. Use a Reliable Email Service Provider (ESP)

Working with a reputable ESP can help improve your email deliverability rate. Providers like Mailchimp, ConvertKit, and SendGrid offer built-in deliverability tools and best practices, making it easier for you to reach your audience.

• Features to Look For in an ESP:

  • Deliverability monitoring.

  • Automated bounce handling.

  • IP warm-up options for large lists.

By choosing an ESP that prioritizes deliverability, you’re giving your emails the best chance to reach their intended recipients.
