DMARC setup walkthroughs by provider

Pick the provider that hosts your DNS (Domain Name System) or sends your mail. Each page shows where the DMARC (Domain-based Message Authentication, Reporting and Conformance) record goes in that provider's console and what to type in each box.

What the DMARC record does

A DMARC record is one TXT (Text) record at _dmarc on your domain. It tells receivers what to do with mail that passes neither SPF (Sender Policy Framework) nor DKIM (DomainKeys Identified Mail) in alignment with your From domain, and where to send reports about it.

Start with p=none and a reporting address, read the reports, and raise the policy to quarantine or reject once every service that sends as you passes.
