How to Authenticate an Email in Gmail

To authenticate an email in Gmail, set up SPF, DKIM, and DMARC for your domain in Google Workspace so your outgoing mail is verified and reaches recipients' inboxes.

For Google Workspace senders

Gmail and Workspace need the same three records. Publish an SPF record that includes Google's mail servers, turn on DKIM in the Google Admin console and publish the key it generates, and add a DMARC record for your domain. Google's own reputation via google postmaster then reflects how you're doing.

Checking it worked

Send a message and view the original in Gmail, which shows SPF, DKIM, and DMARC pass or fail per message. A spam test email gives the same result plus a content score. The general setup and alignment rules are on the authentication page.

How Nitrosend handles it

If you send through Nitrosend, the records are provisioned automatically rather than configured by hand in the Admin console, and the compliance layer confirms they pass.
