# Sending domains

## Sending domains

> Add SPF, DKIM, and DMARC so mail sends from your domain.

To send from your own domain you publish a few DNS records so mailbox providers trust the mail is really from you. Add the domain under Domains (/dashboard/domains) and copy the generated records to your DNS provider.

- DKIM — a TXT record that lets us cryptographically sign your mail.
- MAIL FROM — a custom return-path subdomain for SPF alignment.
- DMARC — a policy record that tells receivers what to do with unaligned mail.

Verification is continuous, not one-shot. A domain is Verified, Degraded, or Unverified, and we keep re-checking the records over time.

> **Degraded still sends:** You can send from a Verified or Degraded domain. Degraded means some records drifted but mail still flows — fix the flagged records to return to Verified. You cannot send from an Unverified domain.
