Google Workspace DMARC
Google Workspace requires you to publish DMARC in DNS. Combine it with Google SPF and DKIM so Gmail and other receivers can authenticate your mail.
What to configure
Publish _dmarc with rua, enable DKIM in the Admin console, keep include:_spf.google.com accurate, and monitor before p=reject.
v=DMARC1; p=none; rua=mailto:[email protected]Common pitfalls
DKIM generated but never started, SPF duplicated after migrations, marketing tools sending as the primary domain without aligned DKIM.
How QuickDMARC helps
Monitor Google Workspace domains alongside Microsoft and ESP traffic in one DMARC program.
Frequently asked questions
Does Google publish DMARC for me?
No. You add the _dmarc TXT at your DNS host.
Bulk sender rules?
Google's sender guidelines expect SPF, DKIM, and DMARC for bulk senders—see our requirements page.
SPF only?
Insufficient. Enable DKIM and DMARC reporting.
