Select every ESP that sends email from your domain, set your policy, and copy the ready-to-paste DNS record. Missing a provider = bounced emails.

SPF record added? Here's what's next.

SPF is a one-time setup - but it breaks when you add a new ESP and forget to update it. MailPilot validates authentication on every connected mailbox and alerts you when records break. Free forever during early access.
