Email deliverability checker
Check that your domain is set up to send cold email: MX, SPF, DKIM and DMARC, with a score and a fix for anything missing.
Why it matters
Since 2024, Gmail and Yahoo expect SPF, DKIM and DMARC from anyone sending in volume. Missing records are the most common reason cold email lands in spam.
What we check
We read public DNS only. DKIM is checked at the selectors common providers use; if yours uses a custom one, it may show as missing even when it's set up.
