Email deliverability is crucial for ensuring that your emails reach your subscribers’ inboxes rather than their spam folders. High deliverability rates improve engagement, enhance your reputation, and maximize the effectiveness of your email marketing campaigns. Here are some best practices to help you improve email deliverability and ensure your messages are seen by your intended audience.
1. Maintain a Clean Email List
Keeping your email list clean and up-to-date is essential for good deliverability. An outdated or poorly maintained list can lead to high bounce rates, spam complaints, and poor sender reputation.
Tips for List Maintenance:
- Regularly Remove Inactive Subscribers: Remove or re-engage subscribers who haven’t interacted with your emails in a long time.
- Use Double Opt-In: Confirm new subscribers’ email addresses with a double opt-in process to ensure they are valid and interested.
- Implement List Hygiene Tools: Use tools to clean and validate email addresses in real time.
Example: Use a tool like ZeroBounce or NeverBounce to validate and clean your email list.
Fact: According to Mailchimp, regularly cleaning your email list can increase your open rates by up to 30%.
2. Authenticate Your Emails
Email authentication helps verify your identity as a sender and improves your chances of getting past spam filters. Implementing authentication protocols can enhance your email reputation and deliverability.
Key Authentication Protocols:
- SPF (Sender Policy Framework): Verifies that the sending server is authorized to send emails on behalf of your domain.
- DKIM (DomainKeys Identified Mail): Adds a digital signature to your emails to ensure they haven’t been tampered with.
- DMARC (Domain-based Message Authentication, Reporting & Conformance): Helps protect your domain from being used in email spoofing and phishing attacks.
Example: Configure SPF, DKIM, and DMARC records in your domain’s DNS settings.

3. Monitor Your Sender Reputation
Your sender reputation influences how your emails are treated by ISPs and spam filters. A good sender reputation increases the likelihood of your emails landing in the inbox.
Ways to Monitor and Improve Sender Reputation:
- Check Blacklists: Regularly monitor if your IP or domain is listed on any email blacklists using tools like MXToolbox.
- Review Bounce Rates: High bounce rates can negatively impact your reputation. Aim for a bounce rate below 2%.
- Track Spam Complaints: Minimize spam complaints by ensuring relevant and valuable content and providing easy unsubscribe options.
Example: Use SenderScore to monitor your sender reputation score.
Fact: According to Return Path, 20% of email marketers’ messages don’t reach the inbox due to poor sender reputation.
4. Craft Relevant and Engaging Content
Content relevance and engagement can affect your email deliverability. Emails that are relevant and engaging are more likely to be opened and less likely to be marked as spam.
Content Best Practices:
- Personalize Your Emails: Use subscriber data to tailor content to individual preferences and behaviors.
- Avoid Spammy Words: Refrain from using words or phrases that might trigger spam filters (e.g., “Free,” “Earn Money”).
- Optimize for Mobile: Ensure your emails are mobile-friendly as a large portion of users check emails on their smartphones.
Example: Personalize subject lines and content based on subscriber preferences to increase engagement.

5. Implement a Consistent Sending Schedule
Consistency in your sending schedule helps build trust with your subscribers and ISPs. An irregular or unpredictable sending pattern can raise red flags.
Scheduling Tips:
- Set a Regular Frequency: Determine a consistent schedule for sending emails (e.g., weekly, bi-weekly) and stick to it.
- Avoid Sudden Spikes: Gradually increase your email volume if you’re scaling up your campaigns to avoid being flagged as spam.
Example: If you send weekly newsletters, maintain that schedule to build anticipation and trust with your subscribers.
Fact: Email service providers prefer consistent sending patterns, which helps in maintaining a good sender reputation.
6. Provide Easy Unsubscribe Options
Making it easy for recipients to unsubscribe helps reduce spam complaints and maintain a healthier email list. It also enhances user experience and trust.
Unsubscribe Best Practices:
- Include an Unsubscribe Link: Ensure every email includes a clear and easily accessible unsubscribe link.
- Offer Preferences: Allow subscribers to manage their email preferences or frequency instead of unsubscribing completely.
Example: Include a “Manage Preferences” link in your email footer to give recipients control over their email settings.

7. Use a Reputable Email Service Provider (ESP)
A reputable ESP provides the tools and infrastructure needed to ensure high deliverability rates and compliance with best practices.
Features to Look for in an ESP:
- Deliverability Tools: Look for features that help monitor and improve deliverability.
- Analytics and Reporting: Choose an ESP that provides detailed insights into your email performance.
- Compliance: Ensure the ESP complies with regulations like GDPR and CAN-SPAM.
Example: Providers like Mailchimp, Sendinblue, and HubSpot offer robust deliverability tools and analytics.
Fact: Using a reputable ESP can improve your email deliverability by providing tools and support to maintain best practices.
8. Test Your Emails
Testing your emails before sending them can help identify issues that may affect deliverability. This includes testing for spam triggers, broken links, and formatting problems.
Testing Tips:
- Use Spam Testing Tools: Tools like Litmus and MailTester can check if your email is likely to be flagged as spam.
- Preview on Multiple Devices: Ensure your email displays correctly across different devices and email clients.
- Conduct A/B Testing: Test different subject lines, content, and designs to determine what works best.
Example: Test your emails with Litmus to check how they render across various devices and email clients.
