Welcome to the "Learn and Test DMARC" console. Visualizing the communication between email servers will help you understand what SPF, DKIM, and DMARC do and how these mechanisms work.

By sending an email to our DMARC tester, we will analyze your DMARC setup and visualize how an email server will validate the SPF, DKIM, and DMARC.

Think you know DMARC? Prove it by taking our quiz. We'll ask you ten questions and give you more details about the correct answer. Taking the DMARC quiz is an excellent way to learn.

Want to analyze email headers? You can now paste your email headers/source to get a visual explanation of SPF, DKIM, and DMARC perfomance.
