10 Proven Ways to Improve Your Email Deliverability Rate

Email marketing remains one of the most effective channels for reaching customers and driving conversions. However, even the most compelling email campaign won't yield results if your emails aren't reaching your subscribers' inboxes. Email deliverability—the ability to successfully deliver emails to the intended recipients' inboxes—is crucial for the success of your email marketing efforts.

In this article, we'll explore ten actionable ways to improve your email deliverability rate. Whether you're a seasoned marketer or just starting out, these tips will help ensure that your emails land where they belong: the inbox.

1. Maintain a Clean Email List

A clean email list is the foundation of good deliverability. Regularly updating and maintaining your list ensures that you're sending emails to engaged and valid recipients.

How to Maintain Your List:

• Regularly Remove Inactive Subscribers: Identify subscribers who haven't engaged with your emails in the past 6-12 months and consider sending a re-engagement campaign. If they remain unresponsive, remove them from your list.
• Use Double Opt-In: This requires subscribers to confirm their email address before being added to your list, reducing the chances of fake or mistyped emails.
• Monitor Bounce Rates: High bounce rates can harm your sender reputation. Remove hard bounces (invalid email addresses) immediately and keep an eye on soft bounces (temporary delivery issues).

Benefits:

• Reduces bounce rates.
• Improves engagement metrics.
• Enhances sender reputation.

2. Implement Email Authentication Protocols

Email authentication helps ISPs (Internet Service Providers) verify that emails are coming from legitimate sources, reducing the chances of your emails being marked as spam.

Key Authentication Protocols:

• SPF (Sender Policy Framework): Specifies which IP addresses are allowed to send emails on behalf of your domain.
• DKIM (DomainKeys Identified Mail): Adds a digital signature to your emails, allowing the receiver to verify that the email was not altered during transit.
• DMARC (Domain-based Message Authentication, Reporting, and Conformance): Builds on SPF and DKIM, providing instructions to ISPs on how to handle unauthenticated emails.

Implementation Tips:

• Work with your IT team or email service provider to set up these protocols.
• Regularly monitor DMARC reports to identify any authentication issues or unauthorized use of your domain.

Benefits:

• Builds trust with ISPs.
• Protects your brand from phishing and spoofing.
• Increases inbox placement rates.

3. Send Relevant and Engaging Content

ISPs and email clients monitor user engagement to determine email placement. High engagement signals that your emails are wanted and should be delivered to the inbox.

Strategies for Engagement:

• Segment Your Audience: Divide your subscribers into groups based on interests, behavior, or demographics to send more targeted content.
• Personalize Emails: Use the subscriber's name and tailor content to their preferences or past interactions.
• Compelling Subject Lines: Craft subject lines that grab attention but avoid spammy language (e.g., excessive use of exclamation points or all caps).
• Clear Call-to-Action (CTA): Encourage readers to take action, increasing engagement metrics like clicks and conversions.

Benefits:

• Higher open and click-through rates.
• Lower unsubscribe rates.
• Positive signals to ISPs, improving deliverability.

4. Optimize Email Sending Frequency and Timing

Finding the right balance in how often and when you send emails can significantly impact engagement and deliverability.

Best Practices:

• Avoid Overloading Subscribers: Too many emails can lead to unsubscribes or spam complaints.
• Consistency is Key: Set expectations for how often subscribers will hear from you and stick to it.
• Test Send Times: Use A/B testing to determine when your audience is most likely to engage with your emails.

Benefits:

• Maintains subscriber interest.
• Reduces spam complaints.
• Improves overall campaign performance.

5. Monitor and Improve Sender Reputation

Your sender reputation is like a credit score for email deliverability. ISPs use it to decide whether to deliver your emails to the inbox or spam folder.

How to Monitor:

• Use Email Provider Tools: Many ESPs offer reputation monitoring features.
• Check Public Blacklists: Regularly verify if your IP or domain appears on public email blacklists.
• Track Engagement Metrics: Keep an eye on open rates, click-through rates, bounce rates, and spam complaints.

Improvement Strategies:

• Address issues causing low engagement.
• Remove unengaged subscribers.
• Ensure compliance with email marketing laws and best practices.

Benefits:

• Higher inbox placement rates.
• Better engagement and conversion metrics.
• Long-term success of your email campaigns.

6. Avoid Spam Triggers in Content

Certain words, phrases, and formatting choices can trigger spam filters, sending your emails straight to the spam folder.

What to Avoid:

• Spammy Language: Words like "FREE!!!", "Guaranteed", "Act Now", or excessive use of exclamation points and all caps.
• Too Many Images or Links: Emails that are image-heavy or contain numerous links can be flagged.
• Misleading Subject Lines: Ensure your subject line accurately reflects the email content.

Best Practices:

• Keep a balanced text-to-image ratio.
• Use clear and professional language.
• Test your emails with spam checking tools before sending.

Benefits:

• Increases chances of landing in the inbox.
• Builds trust with subscribers.
• Enhances overall email performance.

7. Ensure Mobile-Friendly Email Design

With a significant portion of emails opened on mobile devices, a mobile-friendly design is essential for engagement.

Design Tips:

• Responsive Design: Use email templates that automatically adjust to fit the screen size of the device.
• Readable Fonts: Use legible font sizes and types for easy reading on small screens.
• Simplify Layouts: Single-column layouts work best for mobile viewing.
• Accessible CTAs: Make buttons and links large enough to be easily tapped.

Benefits:

• Improves user experience.
• Increases engagement metrics.
• Signals positive engagement to ISPs.

8. Utilize a Reliable Email Service Provider (ESP)

A reputable ESP can significantly impact your deliverability through their infrastructure, tools, and support.

What to Look For:

• Deliverability Tools: Features like authentication support, spam testing, and analytics.
• Good Sending Infrastructure: High-quality IP addresses and servers optimized for email delivery.
• Compliance Support: Guidance on regulations like CAN-SPAM and GDPR.

Benefits:

• Enhanced deliverability rates.
• Access to professional support and resources.
• Improved email campaign management.

9. Implement a Preference Center

Giving subscribers control over the content they receive can reduce unsubscribes and spam complaints.

Features to Include:

• Email Frequency Options: Let subscribers choose how often they receive emails.
• Content Preferences: Allow them to select topics or types of emails they're interested in.
• Easy Unsubscribe: Make it simple to opt-out if they choose.

Benefits:

• Higher engagement rates.
• Lower spam complaints.
• Better subscriber satisfaction.

10. Implement Gradual Volume Increases for New Sending Domains

When using a new email domain, gradually increase your sending volume rather than immediately sending bulk emails.

Recommended Approach:

• Start Small: Begin with a small number of emails to your most engaged subscribers.
• Gradual Scaling: Slowly increase volume week by week as you establish a positive sending history.
• Monitor Closely: Pay special attention to deliverability metrics during this ramp-up period.

Benefits:

• Helps establish a positive sender reputation from the start.
• Reduces the risk of triggering spam filters.
• Creates a foundation for long-term deliverability success.
