How this works
  1. 1
    List who can send mail

    Add each service that sends email for you — Google, Mailchimp, your own server.

  2. 2
    Pick the strictness

    Choose ~all (soft fail) or -all (hard fail). Most people start with ~all.

  3. 3
    Copy the SPF record

    Paste the TXT record into your DNS — it protects your domain from spoofing.

Watch: form → SPF DNS record
Policy
TXT record
v=spf1 a mx ip4:203.0.113.10 include:_spf.google.com -all

Length: 57 chars

Publish as a TXT record on the root of your domain (host @).

How this works
  • Add the IPs and services that send mail for you.
  • Pick a policy — start soft (~all) and tighten to strict (-all).
  • Copy the TXT record into your DNS provider.
Built locally — no calls to your DNS provider.
