Email Auth Health Check

Score SPF, DKIM, DMARC, and MX together.

How it works

One-domain email auth health score

Scores MX + SPF + DMARC + DKIM (tries common selectors, or use yours) so you know if MailShrine / provider DNS is ready for deliverability.

Or start from a real-life example

Results appear here after you click Run health check.

Sending via API? MailShrine Developer API needs the same SPF / DKIM / DMARC setup as any other ESP.
