Free SPF, DKIM and DMARC checker: is your email landing in spam?
Enter your domain. We check the public records that Gmail and Outlook use to decide whether to trust your email: SPF, DKIM, DMARC and MX.
Four records, in plain English.
SPF
A list of the servers allowed to send email for your domain. Without it, anyone can claim to be you, so inboxes treat your mail with suspicion. You should have exactly one SPF record, and it should end in -all or ~all.
DKIM
A digital signature added to each email, proving it wasn't altered on the way. It lives under a "selector" name chosen by your email provider, so a quick check can only look at the common ones. A missing result here doesn't always mean DKIM is off.
DMARC
Tells receiving servers what to do when SPF or DKIM fails, and where to send reports. Since 2024, Google and Yahoo require a DMARC record from anyone sending in bulk. A policy of p=none only monitors; quarantine or reject protects.
MX
Where your incoming email goes. It also tells us which provider you use, which helps diagnose the rest.
Why this matters for cold email
Outreach from a domain with broken records starts with a trust deficit. Before we send a single email for a client, all three authentication records are in place on every sending domain.
Twenty minutes. We bring the research.
Before the call we pull your hiring signals, your reviews and your email setup, so the conversation starts with your numbers, not our pitch.
