SPF syntax error – how to fix

Your SPF record has a syntax problem (permerror or invalid mechanism). Here's how to correct it.

Why it matters

Invalid syntax can cause receivers to treat your SPF as failed or to ignore it. Typos in mechanisms, missing all, or multiple SPF records are common causes.

How to fix it

Ensure the record starts with v=spf1 and ends with an all mechanism (-all or ~all).

Check for typos in include:, ip4:, ip6:, a, mx, and other mechanisms.

Use only one SPF record per domain; merge multiple records into one.

Keep each TXT string under 255 characters; use multiple strings if your DNS supports it.
