SPF Record Validator

Paste a record as text and we will parse the syntax and count DNS lookups without waiting for it to be published. Handy while a record is still a draft, or when someone else wrote it.

Optional. Only needed when the record uses a or mx mechanisms without an explicit host.

When this is useful

  • Before publishing: see the lookup count before a receiving mail server does.
  • When adding a sending service: find out whether one more include still fits in the remaining budget.
  • When reviewing work: validate what a contractor or a vendor guide proposes.
  • When studying someone else's setup: see what a competitor's or partner's record is actually made of.

What to paste

Just the TXT value — the string that starts with v=spf1. There is no need to copy the record name, type or TTL from your DNS panel. Surrounding quotes are stripped automatically if they come along with the text.

Record is fine — what about the list?

A correct SPF record does nothing about dead addresses and spam traps in your mailing list. uChecker cleans it before you send — the first 100 addresses are free.
