if you find yourself struggling with your emails that you are sending out, people telling you that they have not received it or that it constantly lands in their spam box, here is a great, free and simple way to quickly test the quality of our own email sending setup and newsletters.
How does mail-tester work?
They generate a random email address each time you access their port.
You should send a message from your favourite newsletter/email software to this email address using the email address that creates problems.
Once done, click on the Check your score button and as soon as they receive your message, they snail will stop to give you your spam score.
Mail-tester will analyze your message, your mail server, your sending IP... and show you a detailed report of what's configured properly and what's not.
Your result will be accessible for 7 days with their free version or 30 days if you created an account and used your own prefix.
If you send a new message to the same testing address, your previous test will be immediately deleted to be replaced by the new one.
