What is Mail-Tester
Mail-Tester checks whether your emails are likely to trigger spam filters. It delivers a detailed report within minutes so you can fix issues before launching campaigns. The tool is built for teams that depend on reliable inbox placement.
Overview
Mail-Tester evaluates your email content, sending server configuration, and IP reputation against multiple spam filters. You send a message to a unique address provided by the platform and receive a scored report highlighting what passes and what needs attention. The report covers SPF, DKIM, and other authentication records alongside content-based spam signals. This makes it useful as a pre-send quality check alongside your existing CRM or email marketing platform. It does not replace a full spam filter or email service provider. It is a focused diagnostic tool that helps you improve deliverability before messages go live.
How to use Mail-Tester
Copy the temporary address generated on the Mail-Tester homepage and send your email to it. Return to the page and click the results link to view your spam score and a breakdown of every check performed. Teams typically run this test before each campaign send to catch configuration or content issues early.
