Securing Inbox Delivery with SPF, DKIM & DMARC

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.

The Benefits

  • Reduced spoofing, tampering, spam
  • Improved inbox placement and delivery
  • Enhanced email security and compliance

With SPF, DKIM, and DMARC implemented, recipients can trust your emails are legitimate and untampered.
