Do your emails actually arrive?
A quote that lands in spam is a job that goes to someone else, and you never find out. Enter your domain and we read the three records that decide whether your email reaches inboxes or spam folders (SPF, DKIM and DMARC), live, and grade each one. Nothing stored, no signup.
Somewhere to deliver to (MX)
Proof it’s really you (SPF)
A tamper-proof signature (DKIM)
Your instructions to inboxes (DMARC)

All 40 faults the report looks for, each with what it means and what to do about it, ordered by what costs you most. Sent immediately, automatically. One email, not a sequence.
What the SPF checker reads
SPF is a public note on your domain naming the servers allowed to send email as you. Inboxes check arriving mail against it. No note, or a loose one, and a forger can send as your address all day, which drags your real mail towards spam with it. The checker above reads the note and tells you whether it exists and whether it actually restricts anything.
What the DMARC checker reads
DMARC is your standing instruction to inboxes: what to do with mail that claims to be you but fails the checks. Reject it, quarantine it, or wave it through. The big mailbox providers increasingly expect the instruction to exist and to enforce something. The checker reads yours and tells you which of the three you have, in plain words.
