Email Security Challenges
Spoofing, tampering, and spam obstruct email delivery. Fortunately, SPF, DKIM, and DMARC help address these issues.
How SPF Verifies Senders
SPF confirms sending servers by cross-checking IPs published in DNS. This prevents spoofing.
DKIM Ensures Integrity
DKIM cryptographically signs emails to certify they haven't been altered in transit.
DMARC Leverages SPF & DKIM
DMARC uses SPF and DKIM to check authentication and set email routing policies.
Setting Up Email Authentication
Add TXT records for SPF, DKIM, and DMARC in DNS according to provider guidelines.
With SPF, DKIM, and DMARC implemented, recipients can trust your emails are legitimate and untampered.
