DMARC Record Checker

Check any domain’s DMARC policy. Gmail & Yahoo now require DMARC to deliver bulk mail — and a strong policy is worthless if you send to dead addresses that bounce.

DMARC tells receivers what to do with spoofed mail. It can’t tell you if your recipients exist — Engage verifies each address (incl. Microsoft 365) so your good reputation isn’t wasted on dead inboxes.
