Common questions
Where do I add the SPF record?
In your DNS provider, add a TXT record on your root domain (the host is usually @) with the generated value. Changes can take up to an hour to propagate.
Why only one SPF record?
A domain can publish only one v=spf1 record. This generator merges every sender into a single record so you stay compliant.
What if my provider isn't listed?
Add it as a custom include: or ip4: mechanism. Check your provider's docs for the exact include domain they require.
Should I use -all or ~all?
Start with ~all (soft fail) while you confirm every sender is covered, then tighten to -all (hard fail) for maximum protection.
