Check your mail domain in one go
Enter your domain and we check DMARC, SPF, DKIM, MTA-STS, DNSSEC, BIMI and TLS. You get a score from A to F and the three most important improvements.
Analysis messages from the checker are currently in Dutch.
How does it work?
The Domain Analyzer looks up your domain's DNS records and rates them for completeness and strictness. Each check counts toward the total score. At the top you see which three changes help most.
Frequently asked questions
What does the score mean?
A means fully in order, F means important protection is missing. The score is indicative and meant to set priorities.
Is my domain stored?
No. The analysis uses public DNS data and is not kept.
Why does the tool not find my DKIM?
DKIM uses a selector you choose yourself. We try common selectors, but for an unusual name use the separate DKIM checker.
Need help with your email security?
We set up DMARC, SPF, DKIM and MTA-STS for you and keep an eye on it, as part of Security and Monitoring.
