What is SPF, DKIM, and DMARC?

You care about keeping your inbox safe from spam and scams, and so do we! That's why we wanted to introduce you to some powerful tools called SPF, DKIM, and DMARC that can shield your email like a virtual bodyguard.

Think of your email as a letter.

  • SPF (Sender Policy Framework): It's like having a trusted list of authorized post offices who can send letters on your behalf. Only those on the list can send "letters" (emails) from your address, making it harder for impersonators to sneak in.
  • DKIM (DomainKeys Identified Mail): It's like adding a special security seal to your letters. This seal verifies that the letter truly came from you and hasn't been tampered with on its journey.
  • DMARC (Domain-based Message Authentication, Reporting & Conformance): It's like having a trusted advisor who monitors your incoming mail and tells your mail server what to do with suspicious "letters." It can instruct the server to quarantine or even reject emails that fail SPF and DKIM checks, keeping your inbox clean and secure.

These tools work together to build a strong wall around your inbox, stopping unwanted visitors and ensuring only genuine emails reach you.
