Why are my outgoing emails seen as spam?

It is possible that e-mail you are trying to send may be blocked by our outgoing spam filter. You will see the error message below on the ‘reply-to’ address in this case:

Action: failed
Status: 5.0.0
Remote-MTA: dns; filtermail.eu
Diagnostic-Code: smtp; 550 High probability of spam

Why are my outgoing emails seen as spam?

If e-mail is seen as spam by our outgoing spam filter, improvements to the content of the e-mail are needed.
You can use mail-tester.com ‘s system to check what areas of improvement are possible.

Can you exclude my e-mail address or application from this check?

It is not possible to exclude an e-mail address or application from our anti-spam control.

  1. Now we stop the e-mail, chances are the spam filter on the receiving end does too.
  2. No application is 100% secure. We do not want to create future risk by excluding applications.
