Protect Your Domain From Spoofing and Phishing

Email spoofing and brand impersonation remain among the most common entry points for phishing and business email compromise. SPF, DKIM, and DMARC are the three DNS-based standards that mail receivers use to verify whether a message actually came from the domain it claims. Use the analyzer to inspect suspicious mail, the SPF and DMARC generators to publish records for domains you control, and the disposable email checker to triage signup data before trusting it.
