Spam check
SpamAssassin (built-in) – an email will be checked for spam using the built-in SpamAssassin filter. The result is scored on a scale from 0 to 10:
0...2 (green) is a great result. Most spam filters won't block your email.
2...6.2 (yellow) is an average result. Your email is properly written, but there is still some work to do. Review the list of recommendations and try to improve your email.
6.2...10 (red) is a poor result. Update your email as recommended.
Mail-tester.com check – a proper email will be generated and sent to a random address of the mail-tester.com service. To do that, you must have a completed and operational SMTP server settings profile:
