Email Security Checker

Check if your email is properly protected against spoofing and phishing. We'll test your SPF, DKIM, and DMARC records.

What We Check

SPF

Sender Policy Framework

Tells email servers which IP addresses can send email on your behalf. Prevents strangers from sending emails pretending to be you.

DKIM

Email Signatures

Adds a digital signature to your emails proving they haven't been tampered with. Like a wax seal on a letter.

DMARC

Policy Enforcement

Tells receiving servers what to do with emails that fail SPF or DKIM checks. You choose: deliver, quarantine, or reject.

Mail Servers

Checks your mail server records and verifies they support secure connections (TLS/STARTTLS).

Scammers can send emails that look like they're from your domain, tricking your customers and damaging your reputation.

Gmail, Outlook, and other providers check these records. Missing them means your legitimate emails may not reach inboxes.

SPF, DKIM, and DMARC work together to verify email authenticity, preventing phishing attacks that target your customers.
