What it does
- Reads a domain’s public DNS - MX, SPF, DKIM, DMARC, MTA-STS, TLS reporting and BIMI - and the blocklists its mail servers might be on.
- Grades the domain out of 100 and says exactly which record to add, in the form you can paste into your DNS.
- Reads the DMARC aggregate reports large providers send, and shows every server sending mail as your domain and whether it passed.
- Re-checks daily and emails you if a record changes or disappears.
- Free to check any domain, with no account.
