Email Checker.

See whether a domain can send email that inboxes trust. We look up the public SPF, DKIM, and DMARC records.

Check SPF, DKIM, and DMARC.

A missing or loose record is a common reason mail lands in spam. This check is a snapshot. For a written report with copy-paste fixes, order the DNS + Email Deliverability Audit.

Frequently asked questions.

01What is SPF?

SPF is a TXT record that lists who may send mail for the domain. A record that ends in -all rejects everyone else. +all lets anyone send as you.

02What is DMARC?

DMARC tells inbox providers what to do when SPF or DKIM fails. p=none only monitors. p=quarantine and p=reject are what actually stop spoofed mail.

03Why can DKIM show as missing when I have it?

DKIM lives under a selector, such as google._domainkey. We try the usual selectors, and you can type a custom one. Shopify and Microsoft often publish the key as a CNAME, and that still counts as found.
