Free SPF & DMARC Checker

Check any domain's SPF and DMARC setup — the records that decide whether your email reaches the inbox or spam.

SPF, DKIM & DMARC in plain English

SPF says which servers may send email for your domain. DMARC tells receivers what to do when a message fails checks — and a policy of p=none only monitors, it doesn't protect. Since 2024, Google and Yahoo require SPF + DMARC for bulk senders, so a missing or weak record is the most common reason legitimate mail lands in spam — or gets spoofed. VigilDog watches these records on every client domain and alerts you the moment they break or weaken.

Frequently asked

Why is my email going to spam?
The most common causes are a missing or broken SPF record, no DMARC policy, or a DMARC policy of p=none. Gmail and Yahoo now require SPF + DMARC for bulk senders.
What DMARC policy should I use?
Start at p=none to monitor, then move to p=quarantine and finally p=reject once you confirm legitimate mail passes. p=none alone does not stop spoofing.
Does this check DKIM?
This tool checks SPF and DMARC presence and policy. DKIM is selector-specific; VigilDog checks it on monitored domains where the selector is known.

Stop checking by hand.

VigilDog watches this across every client domain, 24/7, and warns you days before anything breaks.
