SPF Generator

Build an SPF record

What is it?

A guided builder for the `v=spf1 ...` DNS TXT record, based on which platforms actually send mail on behalf of your domain.

Why it matters

Hand-writing SPF syntax is easy to get subtly wrong — a missing include or the wrong qualifier either blocks your own mail or fails to protect against spoofing.

Impact if ignored

Same stakes as the SPF Checker above — this just helps you get the record right the first time instead of discovering a mistake after mail starts failing.

Common use cases

  • Setting up SPF for a brand-new domain
  • Adding a newly-adopted sending platform to an existing record
