Email domain health
Email deliverability · Checker · by John KingFreeCheck your SPF, DKIM, DMARC, MX and blacklists, and get the exact DNS record that fixes each problem.Enter the domain you send email from. We read its public DNS the way receiving mail servers do: the SPF record that says who may send for you, the DKIM key that proves a message is yours, the DMARC policy that tells inboxes what to do with fakes, the MX records that receive your mail, and the blacklists that spam filters consult. Each check is pass, fail or warn with the reason, and for every problem you get the exact record to add or change at your DNS provider. Everything is shown in full, no account needed.
