How safe is the mail of your domain?

MX, SPF, DKIM, DMARC, MTA-STS, TLS-RPT and BIMI in one check, read straight from the DNS. Shows what is missing and how to fix it.

Domain or e-mail address

Try

DKIM selectorWe try the selectors of common providers. If yours uses another one, enter it.

Enter a domain like example.com. The checks show up here.

What we pass on

About this check

Everything comes from public DNS records and the MTA-STS policy. No mail is sent.
DKIM keys can only be found by their selector, which is in the header of every mail as s=.
