Stay Ahead of Email Security Risks: Understanding SPF, DKIM, and DMARC

Feb 2024

So, you've probably heard some buzz about SPF, DKIM, and DMARC lately, right?

These acronyms might sound like tech jargon, but they're actually really important for keeping your emails safe and sound.

What are SPF, DKIM, and DMARC?

SPF (Sender Policy Framework): SPF is an email validation protocol designed to detect and prevent email spoofing. It verifies that an email message comes from an authorised sender by checking the sender's IP address against a list of authorized sending IP addresses.

DKIM (DomainKeys Identified Mail): DKIM adds a digital signature to email messages, allowing recipients to verify that the message was sent by the domain owner and hasn't been tampered with in transit.

DMARC (Domain-based Message Authentication, Reporting, and Conformance): DMARC builds upon SPF and DKIM to provide further email authentication and reporting capabilities. It allows domain owners to specify how their emails should be handled if they fail authentication checks, providing greater control and visibility over email traffic.

What's at stake?

These changes are a big deal for email security. Since February 2024, companies like Google and Yahoo have stopped delivering emails if DKIM and DMARC are not configured. It's estimated that thousands of business are at risk but get them right, and you'll keep the bad guys at bay while boosting your email deliverability. However, get them wrong and you could end up with emails marked as spam or worse, damaging your reputation. Worse still, you won't even be aware that you emails are not being delivered!!
