Testing your outgoing email ranking

by Jan Bachelor October 31, 2024
  • You can use mail-tester.com for up to three tests in 24 hours.
  • Once you reach the website, you will be asked to send an email to a unique email address / hostname.
  • Save the email address and create a new email, for example via Roundcube
Mail-Tester – Send Out An Email
  • Then click on the ‘Then check your score button’ to see what you get:
Mail Test – Check Your Rating
  • Hopefully the boat has successfully travelled to new lands and the score is close to 10. With the free version of Brevo, an invisible tracking pixel is inserted by the relay and for some reason, it does not contain an alt tag, which lowers the score:
Mailer Test – Details On Brevo’s Rating
  • The issue of the tracker is discussed a lot on their forum since late 2023. It seems to be present even when anonymous tracking is disabled:
Brevo – Toggle Anonymous Tracking
  • While in my tests, emails to all major providers inc. Google and O365 were delivered fine, if you encounter issues, reach out to Brevo’s support to manually remove the tracking from all transactional emails.
  • An alternative is to sign up for another provider. For instance, Mailer Lite providers 3,000 emails per month for free, which may be enough for some (and it is a decent service).

So with emails working in and out, how about we try connecting to our mail server via IMAP using an email client?
