Protecting Your Domain from Phishing Attacks

Hackers frequently spoof domain names to send malicious emails to customers. If your domain isn't locked down, your brand reputation is at risk.

SPF and DKIM

Sender Policy Framework (SPF) tells the world which IP addresses are authorized to send email on your behalf. DKIM adds a cryptographic signature to your emails to prove they weren't tampered with.

Enforcing DMARC

DMARC ties SPF and DKIM together, instructing receiving mail servers (like Gmail) to outright reject any emails claiming to be from you that fail these security checks.
