Interpreting the Results

When you run an MXToolbox Email Deliverability Test, it provides you with valuable insights into your email deliverability. Understanding and interpreting these results can help you identify any issues or areas for improvement. Here’s a breakdown of how to interpret the different aspects of the test:

  1. Blacklist: The Blacklist section shows if your IP address or domain is listed on any known blacklists. Being listed on a blacklist can significantly impact your email deliverability as many mail servers use blacklists to filter out spam.

  2. SMTP Connect: This section indicates whether there was a successful connection between the sending server and the recipient’s server during the SMTP handshake process. A failed connect suggests potential delivery issues.

  3. SMTP Banner: The SMTP banner is what the receiving server displays when it identifies itself during an SMTP transaction. It should contain relevant information about your organization or domain.

  4. SMTP TLS/SSL: This part checks if there is encryption (TLS/SSL) in place when communicating with other mail servers over SMTP connections, ensuring secure transmission of emails.

  5. SPF Records: SPF (Sender Policy Framework) records verify that an email message comes from an authorized server by checking against a list of approved senders specified in DNS records.

  6. DKIM Records: DKIM (DomainKeys Identified Mail) uses digital signatures to authenticate emails, confirming they come from valid sources and haven’t been tampered with during transit.

  7. DMARC Records: DMARC (Domain-based Message Authentication, Reporting, and Conformance) helps prevent email spoofing by providing guidelines for handling suspicious messages that fail SPF or DKIM authentication checks.

  8. MX Records & Reverse PTR: These records ensure proper routing and identification of mail servers responsible for accepting incoming emails for your domain name.

9Diagnostic Codes & Feedback Loop Information: If there are any delivery errors or issues, the test provides diagnostic codes and feedback loop information to help you troubleshoot and address them.

Remember that while the MXToolbox Email Deliverability Test provides valuable insights, it’s always good practice to consult with an email deliverability expert or your IT team for further analysis and guidance on improving your email delivery rates.
