What DomainCanary does
DomainCanary is a DMARC monitoring service that turns your domain's aggregate reports into one weekly email. The paid plans add hosted DMARC, SPF and MTA-STS records, so you change a policy from the dashboard instead of in DNS, and two checks that tell you which SPF senders and DKIM keys are still in use.
