Why It Matters — Email Sender Validation in Plain Language

One of the most critical functions of your DNS configuration is to protect your organization’s email reputation and security. Three key technologies—SPF, DKIM, and DMARC—work together to help prevent email spoofing and ensure your emails reach inboxes instead of spam folders.

Here’s a simple summary:

  • SPF defines which email servers are authorized to send mail on your behalf.

  • DKIM digitally signs your messages so recipients know they’re authentic.

  • DMARC builds on SPF and DKIM, providing clear instructions on how to handle suspicious emails and sending reports back to you.

Properly configuring these settings reduces phishing risk and improves the likelihood that your emails will be delivered successfully.
