If you’re using a custom sender address on Learnybox, it's important to verify its deliverability to ensure your emails are reaching your contacts' inboxes. Here’s how to run a test and improve your score if needed.

How to Run Deliverability Test

1. Access Account Email Settings

  • Navigate to Settings Emails tab.

2. Run Deliverability Test

  • Scroll down to the bottom of the page and you'll see the following option:
    Test the deliverability of your email address
    Click the button below to run the deliverability test.

  • The system will perform a check and return a deliverability score out of 10.

3. Review Results

  • If your score is below 7, review the recommended actions provided in the test report.

  • These typically include configuration updates or domain reputation improvements.

How to Improve Your Deliverability Score

If your test result is low, here are some proven best practices to help improve your score:

Set Up SPF, DKIM, and DMARC

Ensure these essential email authentication protocols are properly configured in your DNS hosting provider:

  • SPF: Authorizes sending servers for your domain.

  • DKIM: Verifies that your emails haven’t been altered.

  • DMARC: Protects your domain from spoofing and phishing.

Use Permission-Based Contact Lists

Always send emails to contacts who have explicitly given consent to receive your email communications. Avoid using purchased or scraped email lists—they can trigger spam filters and harm your domain reputation.

Maintain a Positive Sending Reputation

Focus on:

  • Sending relevant, engaging content, to contacts who open your emails regularly.

  • Reducing complaints, unsubscribes, and bounces.

  • Avoiding "spammy" practices.

Monitor Engagement

Keep a clean email list by removing inactive contacts, and focus on recipients who regularly open and interact with your emails. This helps signal good engagement to email service providers.

Include a Clear Unsubscribe Link

Make it easy for users to unsubscribe. Not only is this a requirement for email compliance, it improves trust and reduces the chances of your emails being marked as spam.

Avoid Spam Trigger Words and Formatting

Steer clear of:

  • Overuse of terms like “Free”, “Act now”, etc.

  • Excessive punctuation or all caps.

  • Emails with large images and little text.

By applying these best practices, you’ll improve the reputation and performance of your sending domain—ensuring your emails land where they belong: in your audience's inbox.
