SPF Record Builder

Build a valid SPF TXT record from includes, IPs, and policy flags.

How it works

Build an SPF TXT record for your domain

Pick who sends mail for you (Google, Microsoft, SES, etc.), add IPs if needed, choose -all or ~all, then click Build SPF record. Copy the TXT value into DNS. This does not look up live DNS — it builds the string.

Or start from a real-life example

Select every ESP / mailbox provider that sends as @yourdomain.com.

Custom include (optional)

IPv4 senders (optional)

What about everyone else?
