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.
