Email Diagnostic & Mail Tester Guide
Testing email deliverability is crucial for marketing and transactional mail. This tool provides a temporary inbox, allowing you to send an email and analyze how it is received.
Supported Inputs
- Send an actual email from your mail client or server to the unique, temporary email address provided on the screen.
How to Interpret the Output
- Received Headers: View the raw email headers to see the routing path.
- Authentication: Checks for the presence and basic alignment of SPF, DKIM, and DMARC in the received headers.
- Diagnostic Score: A custom score based on the presence of proper authentication and clean formatting.
Realistic Example
You send an email from your server to the test address. The results show a score of 10/10 because your server properly signed the email with DKIM and the return path matched your SPF record.
Common Errors & Limitations
- Custom Diagnostics, Not SpamAssassin: This tool relies on a custom checklist of best practices; it does not run the SpamAssassin engine.
- No SMTP Probing: This tool analyzes mail received by it. It does not probe your server’s SMTP configuration or verify if external email addresses exist.
