# SPF record generator

Assemble a v=spf1 TXT record from guided mechanism rows (a, mx, ip4, ip6, include, exists, redirect) with a plain-language explanation per row and a chosen catch-all qualifier, then show the assembled record with copy.

Add a mechanism to build the record.

This generator assembles text only; it never reads DNS, so a row can name a domain that publishes no SPF record and the record still builds. Count the lookups against the limit of 10 before publishing, paste the result as one TXT record on the sending domain's own name, and check the live record afterwards. Include and redirect target domains must publish their own SPF records for the mechanisms to ever match.
