Is your email DNS actually right?

Type a domain and get a plain-English verdict on its MX, SPF, DKIM and DMARC records, with the exact record to add for anything that is missing or wrong. Free, no account needed.

Opens the checker on the AtrioMail panel. Nothing is stored except the domain, your IP address and the result, for 30 days, so we can stop abuse.

MX

Where mail for the domain is delivered. The checker tells you whether the record exists, which server has the lowest priority, and whether a leftover server from an old provider is still listed.

SPF

Which servers may send as the domain. It flags the mistakes that silently break SPF: two records, quotation marks stored in the value, no all mechanism, or more than ten lookups.

DKIM and DMARC

Whether a DKIM key is published for the selector you name, and whether a single, well-formed DMARC policy exists. Signed-in customers also get their exact DKIM key and Amazon SES records verified.

Resellers: check every client domain from your own panel The same check is built into the AtrioMail control panel and the API, so a DNS cutover can be verified before and after without a support ticket.
