Record generator

SPF record generator

Build an SPF TXT record that says exactly which servers may send as your domain — and stays inside the 10 DNS-lookup limit receivers enforce.

Domain

Only used by “Check current record” below — the record itself doesn’t reference it.

IPv4 senders (ip4)

One address or CIDR range per line.

IPv6 senders (ip6)

One address or CIDR range per line.

Third-party senders (include)

One sending domain per line — for services like Google Workspace, an ESP, or a helpdesk.

Authorize the domain’s MX hosts (mx)

Authorize the domain’s own A/AAAA record (a)

If a check fails (all)

Generated record

Look up the TXT record currently published for the domain above and compare it with the record you just built.
