Provider guides

Connect each sending platform to your authentication plan.

Provider setup changes over time. These guides explain what to verify for DMARC and link to the provider's current instructions for the exact DNS values.

The same four checks for every platform

Which visible From domains the platform uses.
Which domain appears in the SMTP Mail From or Return-Path.
Which domain signs with DKIM.
Whether at least one authenticated identifier aligns with the visible From domain.

Do not copy generic DNS values

Use the records generated inside your own provider account. Selectors, account identifiers, regions and return-path domains can differ between customers.

Note

After setup, send representative mail and confirm the source and aligned identifiers in subsequent DMARC reports.

Private testing

Connect a domain when you are ready.

Invitation-only access is free during testing. It will not remain a permanent free service.
