SPF Record Generator

Create a correct SPF record that tells the world which servers may send email for your domain.

Comma or space separated. IPv4 and IPv6 are detected automatically.

Tap a provider above, or add third-party senders manually.

v=spf1 mx ~all

Add this as a TXT record on your root domain.

SPF (Sender Policy Framework) is a DNS TXT record listing the mail servers allowed to send on behalf of your domain. Receiving servers check it to decide whether a message is legitimate — so a correct SPF record improves deliverability and protects your brand from spoofing.

Add the generated record as a TXT record on your root domain, then verify it with a DNS lookup.
