Our mission is to make email server testing accessible to everyone
SMTP Email Tester was created by a team of email system administrators and developers who were frustrated with the lack of simple, accessible tools for testing SMTP configurations.
After years of troubleshooting email delivery issues for clients and explaining the same concepts repeatedly, we decided to build a free, user-friendly tool that would help demystify the email testing process for everyone, from beginners to experienced system administrators.
Since our launch, we've helped thousands of users diagnose and fix their email configuration issues, saving countless hours of troubleshooting time and ensuring critical communications reach their destination.
We believe that reliable email delivery should be accessible to everyone, not just large organizations with dedicated IT teams. Our mission is to provide simple yet powerful tools that help individuals and businesses ensure their emails reach their intended recipients.
By offering our SMTP testing tool for free, we aim to:
