Check your domain's security posture

Domainbuddy checks your domain's SPF, DKIM, DMARC, DNSSEC, MTA-STS, TLS-RPT, BIMI and CAA records. It also identifies your email provider, maps third-party suppliers in the delivery chain, and looks for lookalike domains that could be misusing your brand.

You get a clear overall score and a breakdown by area, so you can quickly see which protections are in place and what still needs tightening.

You can also analyze the headers of an email you've sent and estimate how likely it is to get caught by spam filters.

All data is fetched from public DNS and RDAP sources, and the check doesn't require signing in.
