Tips to Improve Your Email Deliverability

Last Update 2 years ago

As an email marketer or a business owner, you’ve worked hard to create that perfect email campaign. But what if it never reaches your audience’s inbox? Deliverability—getting your email into your recipient’s inbox—is crucial for email marketing success.

Here’s a beginner-friendly guide to help you improve email deliverability using Seamaile and ensure your hard work pays off.

1. Use a Professional Email Address

Free email addresses like Gmail or Yahoo are more likely to be flagged as spam. Instead, use a custom domain (e.g., [email protected]) to enhance your credibility.
Example:

A small consulting agency found their open rates increased by 25% after switching from [email protected] to [email protected].

💡 Pro Tip: A professional email address not only boosts trust but also improves your reputation with email service providers (ESPs).

2. Authenticate Your Email

Authentication is like showing your email provider an ID to prove you’re legitimate. The key protocols are:

  • SPF (Sender Policy Framework): Verifies your domain can send emails.
  • DKIM (DomainKeys Identified Mail): Ensures the email hasn’t been tampered with.
  • DMARC (Domain-based Message Authentication): Prevents phishing or spoofing of your domain.
Why It Matters:

Authenticating your domain with SPF (Sender Policy Framework), DKIM (DomainKeys Identified Mail), and DMARC (Domain-based Message Authentication, Reporting & Conformance) is essential for establishing trust with ISPs. These protocols verify that your emails are sent from a legitimate source.

💡 Pro Tip: Ask your email service provider to help you set up these protocols. They make your emails more trustworthy!
3. Build a Clean Email List

Quality over quantity is key when it comes to your email list. Here’s how to keep it clean:

  • Remove Inactive Subscribers: Regularly prune contacts who haven’t engaged in 6-12 months.
  • Avoid Purchased Lists: These are often full of outdated or fake email addresses and can damage your sender reputation.
Why It Matters: 

Maintaining a clean email list is vital for reducing bounce rates and spam complaints. Regularly remove inactive subscribers and invalid email addresses using validation tools.

Case Study:

An online retailer saw a 20% increase in open rates after cleaning their email list and removing 10,000 inactive contacts.

4. Send Relevant Content

People engage more with emails that interest them. High engagement signals email providers that you’re a trustworthy sender.

  • Segment your audience by preferences, purchase history, or location.
  • Personalize subject lines and content (e.g., “Hi [Name], here’s your exclusive offer!”).
Example:

A travel agency segmented their list into “beach lovers” and “mountain adventurers,” tailoring emails accordingly. This boosted their click-through rate by 30%.

5. Monitor Your Sender Reputation 

Your sender reputation is like your credit score for email marketing. A low score can send your emails straight to spam.
  • Use tools like SenderScore or Postmaster by Google to monitor your reputation.
  • Avoid spammy practices like excessive use of “BUY NOW!!!” or misleading subject lines.
Why It Matters: 

ISPs track sender reputation based on various factors, including bounce rates, spam complaints, and engagement metrics. Regularly monitor these indicators to maintain a good reputation.

💡 Pro Tip: If your score drops, focus on improving engagement with high-quality content and cleaning your email list.
6. Avoid Spam Triggers

Email filters look for certain red flags, including:

  • ALL CAPS in subject lines.
  • Excessive exclamation points (e.g., “Act Fast!!!”).
  • Misleading promises (e.g., “You’ve won $1,000!”).
Why It Matters:

 Certain words and phrases can trigger spam filters, causing your emails to be marked as spam. Avoid using overly promotional language or "spammy" phrases like “free,” “urgent,” or “act now".

Example:

A software company reduced their bounce rates by 15% after rewording their subject lines to be more professional and informative.

7. Optimize for Mobile

Over 50% of emails are opened on mobile devices. If your emails aren’t mobile-friendly, recipients may delete them or mark them as spam.

  • Use responsive design to ensure readability on all devices.
  • Keep subject lines under 50 characters.
💡 Pro Tip: Test your emails on multiple devices before hitting send!
8. Monitor Email Metrics

Tracking your performance helps you spot and fix problems quickly. Key metrics to watch include:

  • Bounce Rate: High rates could mean your list has invalid addresses.
  • Spam Complaints: If many people mark your email as spam, you’ll need to improve your content or targeting.
Case Study: Bounce Rate Rescue

A nonprofit organization found their bounce rate was 20% due to outdated email addresses. After using an email verification tool to clean their list, it dropped to just 3%, improving deliverability dramatically.

9. Test Before You Send

Run tests to catch potential issues:

  • Use tools like Litmus or Mail Tester to check for spam triggers and formatting errors.
  • Send test emails to your team and review on various devices.
10. Send Consistently, But Not Too Often

Consistency builds trust, but overloading your audience can lead to unsubscribes.

  • Create a schedule (e.g., weekly or biweekly) and stick to it.
  • Respect your audience’s inbox by focusing on value, not just sales pitches.
Conclusion: Inbox Success Starts Here!

Improving email deliverability isn’t rocket science—it’s about building trust and providing value. By following these tips, you’ll not only increase the chances of your emails landing in inboxes but also build stronger relationships with your audience.
