Mail-tester is a deliverability test tool for analyzing specific emails and their content by sending your message from your favorite newsletter/email software to its email address.

More Details

Mail-tester generates a random email address each time you access its port. You should send a message from your favorite Newsletter/email software to this email address.

Once done, click on the Check your score button, and as soon as it receives your message, its snail will stop to give you your spam score.

Mail-tester will analyze your message, mail server, and sending IP… and show you a detailed report of what’s configured properly and what’s not.

If you send a new message to the same testing address, your previous test will be immediately deleted and replaced by the new one.
