SPF / DKIM / DMARC Record Generator
Build and validate email auth records without guesswork.
SPF / DKIM / DMARC Record Generator helps you stop email spoofing on your own domain by building correct SPF and DMARC TXT records from a simple form — no more hand-editing cryptic strings. Its built-in Validate mode parses any existing record and flags common syntax mistakes like a missing terminal "all" mechanism, too many DNS lookups, or malformed DMARC tags. It's a client-side builder and syntax checker, not a live DNS tool — always confirm what's actually published with a real DNS query.
