Fraudmarc’s email authentication service will automatically repair errors that a SPF record checker reveals. If you don’t mind risking non-delivery of your business emails, have a go at fixing the record yourself with guidance from the RFC: https://tools.ietf.org/html/rfc7208.
Properly implementing SPF is an essential part of DMARC implementation. We provide a DMARC check tool to examine DMARC policies.
SPF errors are widespread because simple tasks like activating new email vendors can overflow and invalidate your policy.
