Free Email Security Checker (SPF, DKIM, DMARC)
Check your domain's email authentication - SPF, DKIM, and DMARC - and see if you're vulnerable to spoofing.
Frequently asked
Which DKIM selectors are checked?
The tool probes the five most common selectors: default, google, selector1, selector2, and k1.
What is a weak DMARC policy?
A DMARC record with p=none only monitors mail - it does not reject or quarantine spoofed messages. Move to p=quarantine or p=reject.
