# SPF, DKIM and DMARC

SPF, DKIM and DMARC are three email authentication methods tied to DNS. SPF lists allowed senders. DKIM signs messages. DMARC tells receivers what to do when the checks fail.

## Why it matters

These settings protect a domain's email from spoofing and improve inbox delivery. When a domain changes hands, the new owner should set them up before sending mail. A domain with no records may land in spam. They are stored as DNS records, usually TXT. A common mistake is keeping the old owner's records after a sale, which can send mail to the wrong place or fail checks. Review them as part of the transfer.
