Introducing SpamAssassin Integration in ColdEmailingJet: Analyze and Optimize Your Email Content

At ColdEmailingJet, we’re always looking for ways to empower our users with tools to improve email deliverability and engagement. That’s why we’re excited to announce the integration of SpamAssassin, a robust open-source platform for email spam detection. This new feature helps you analyze and optimize your email content, ensuring it gets delivered to your recipient’s inbox and avoids the dreaded spam folder.

How SpamAssassin Works with ColdEmailingJet

When you send an email through ColdEmailingJet, a unique email address is automatically generated based on your device key. If you enable the seed feature, ColdEmailingJet will send a test email to this address. The email will then be processed by SpamAssassin, which assigns it a spam score.

You can access these scores and detailed reports directly within the SpamAssassin menu in the app. This feature enables you to:

  1. View the Spam Score: Understand how SpamAssassin evaluates your email.
  2. Diagnose Issues: Identify any problems that might increase your email’s spam score.
  3. Iterate and Improve: Send updated versions of your email to the same address and compare the results to refine your content.

Reading a SpamAssassin Report

A SpamAssassin report provides a detailed breakdown of the factors affecting your spam score. The report starts with an overview like this:

X-Spam-Status: No, score=-3.9 required=5.0 tests=DKIM_SIGNED,DKIM_VALID,  
DKIM_VALID_AU,RCVD_IN_DNSWL_NONE,SPF_PASS  

This line tells you:

  • Overall Score: Whether your email is flagged as spam. In this case, a score of -3.9 (well below the threshold of 5.0) indicates the email is safe.
  • Tests Run: The specific tests SpamAssassin used to evaluate your email, such as DKIM validation, SPF records, and RBL checks.

Key Insights from the Report

The detailed section of the report highlights the points each test contributes to your score. Here’s an example:

pts rule name              description  
---- ---------------------- --------------------------------------------------  
-3.0 RCVD_IN_RP_CERTIFIED  Sender in ReturnPath Certified  
-0.1 DKIM_VALID_AU         Message has a valid DKIM signature from author's domain  
0.0 HTML_MESSAGE           BODY: HTML included in message  
1.3 RCVD_IN_RP_RNBL        Relay in RNBL, possible issue with reputation  

Focus Areas for Improvement

  1. Authentication Records: Ensure that your emails pass DKIM (DomainKeys Identified Mail) and SPF (Sender Policy Framework) tests. These are critical for demonstrating email authenticity.
  2. Reputation Management: Pay attention to RBL (Real-time Blackhole List) results, which evaluate your sender reputation.
  3. Content Structure: Avoid patterns flagged as spam, such as excessive HTML or links from untrusted sources.

Practical Use Case

Imagine sending an email and receiving the following feedback:

  • SPF_PASS: Your domain’s SPF record is correctly set up.
  • DKIM_VALID: Your email includes a valid DKIM signature.
  • HTML_MESSAGE: SpamAssassin notes the presence of HTML, but it’s not inherently bad—just ensure it’s minimal and relevant.

If you notice a high score due to an issue like RCVD_IN_RP_RNBL, you can investigate and address the flagged reputation concern. After making changes, send another test email and compare the updated report to measure improvement.
