What even is DKIM, SPF and DMARC?

Dedicated. Data-driven. Digital Marketing.

Missed the boat on adding DKIM & SPF to your email domain and now seeing your marketing emails are getting rejected or their effectiveness has dropped?

You now have to set authentication records on your email domain to get your marketing emails delivered into Gmail/Yahoo inboxes and it’s likely other providers will follow soon.

But what even is DKIM, SPF and DMARC?

DKIM (Domain Keys Identified Mail)

This is a way to store a “public key” on your domain which email servers, like Gmail, check to see if it pairs with the “secret key” which is sent in the header of your email; proving that you are the legitimate sender.

SPF (Sender Policy Framework)

This defines the email servers which you use to send email such as email. mymailserver .com, you should define all of your mail servers such as your email marketing platform, business email server and any transaction email server you may use.

Both DKIM and SPF prevent other people “spoofing” emails from other servers pretending to be you.

DMARC (Domain-based Message Authentication Reporting & Conformance)

This is a way email providers/administrators set policy rules based on whether DKIM and SPF authentication fails. For instance they can set the policy to direct email which failed authentication to spam, reject it completely or do nothing. More recently Gmail and Yahoo have set this to reject all non-authenticated email.
