SPF Generator

Generate an SPF record.

Pick your sending sources and get a ready-to-publish SPF TXT record.

How to publish your SPF record

Add the generated string as a single TXT record at your domain's root (@). A domain must have exactly one SPF record — if you already send through multiple providers, combine them into one record using include: mechanisms rather than publishing several TXT records.

Already have a record and want to verify it? Use the SPF Checker.
