Email security check,
in seconds.

Validate SPF, DKIM, and DMARC records to protect your domain from spoofing and improve email deliverability.

SPF Record DKIM Selectors DMARC Policy Provider Detection

SPF

Sender Policy Framework validation: checks whether the record exists, parses the policy, and explains what it means in plain English.

DKIM

Checks common DKIM selectors against your domain to detect configured keys. Identifies the email provider from the signing domain.

DMARC

Validates the DMARC policy record, parses the policy action (none / quarantine / reject), and explains the reporting configuration.

Why Email Security Records Matter

Prevent spoofing & phishing

SPF, DKIM, and DMARC together prevent malicious actors from sending emails that appear to come from your domain, protecting your brand and your customers.

Improve inbox delivery

Gmail, Outlook, and other providers use these records to score email legitimacy. Correct configuration significantly improves the chance your emails reach the inbox rather than spam.

How each record works

SPF : lists the IP addresses and services authorised to send email for your domain.
DKIM : adds a cryptographic signature to outgoing email, letting receivers verify the message hasn't been tampered with.
DMARC : ties SPF and DKIM together with a policy telling receivers what to do with emails that fail authentication.
