Your CRM has its own records.
A generic SPF check tells you the record parses. It does not tell you whether it matches what your platform actually requires, the exact include, the exact CNAME targets, the selector names. We hold your DNS against 25 vendors' published specs, character by character. No account, no card.
Not sure which one you are on? Leave it to detection, we read your live DNS and tell you. Or pick a platform below and we go straight there.
