What Are DMARC, SPF, and DKIM? WordPress Email Authentication Guide (for Beginners)
When you send an email, there's no built-in way to prove it's really from you. Scammers use this weakness to send millions of fake emails every day. They pretend to be banks, companies, or even your boss.

In this article, I'll explain how DMARC, SPF, and DKIM work together to verify your outgoing mail and make sure your messages always get through.
