About the email test

After you enter a domain name of an email service, we will test if the email service offers support for the modern Internet Standards below.

Note: some standards are even relevant if there are no mail servers configured for your domain.

Test report

After the test is finished, you are directed to a test report with detailed explanations. The report contains an overall percentage score and results per test section and per subtest. For more information see "Explanation of score and icons".

How to improve

You can use this test report to improve the mail service that you use. Usually contacting your mail hoster on this will be the best next step.

Scope

The e-mail test checks for important modern internet standards that contribute to reachability and security. It should not be considered as an all-encompassing security test for e-mail.
