Free Email Deliverability Checker
Is your website's contact form actually reaching your inbox? Check SPF, DKIM, DMARC, and MX records in plain language — the exact class of check that found why our own contact form was silently failing.

Checked
What this tool checks
MX records
Confirms your domain can actually receive email at all, and where it's routed.
SPF record
Whether your domain authorizes which servers can send mail as you — and flags duplicate records, a common misconfiguration.
DKIM record
Checks common selector names for a DKIM signing key, used to cryptographically verify your mail wasn't altered in transit.
DMARC record & policy
What happens to mail that fails authentication — monitored, quarantined, or rejected outright.
Enforcement risk
Whether a strict DMARC policy combined with missing SPF/DKIM is actively causing mail to be dropped right now.
Plain-language explanations
No raw DNS jargon dumped on you — every result explains what it actually means for your inbox.
We built this after finding — on our own domain — that a strict DMARC policy combined with a missing SPF record was silently sending our own contact form submissions to nowhere. The website reported success. The email never arrived. If your form has ever felt too quiet, this is worth two minutes to check.
Frequently asked questions
What is SPF and why does it matter?
SPF lists which servers are allowed to send email as your domain. Without it, receiving servers can't verify your mail is legitimate — a common cause of silent delivery failures.
What is DMARC and why does it matter?
DMARC tells receiving servers what to do when SPF or DKIM checks fail — monitor, quarantine, or reject. Without it, there's no consistent policy or reporting.
My contact form emails aren't arriving. Could this be why?
Very likely, yes — this is one of the most common causes, and it's exactly what this tool is built to catch.
