Understanding email authentication protocols:


Why do I need to authenticate my domain?

In a nutshell, if your domain is not authenticated it will lead to several issues, including:

  • Your emails being marked as spam

  • You are at higher risk of phishing attacks

  • Your emails may not even be delivered

  • There will be a loss of trust in your domain

  • Giving opportunity to others to spoof or tamper with your emails

Ensuring authentication protocols are in place on your email-sending domains is a non-negotiable now if you want to land in your prospect's inbox!

With the new Gmail and Yahoo updates in 2024, these protocols must be implemented correctly before engaging in any outreach.


What do I need to authenticate?

Yes, techy terms can look daunting, but they are really very simple and easy to understand at a top level. The following protocols will need to be implemented:

  • ​SPF - this proves you actually sent the email

  • ​DKIM - this confirms your email has not been changed by someone else along its journey

  • ​DMARC - tells the recipient what to do if they receive an email that has failed the SPF or DKIM checks. It also provides some reporting, allowing you to monitor any deliverability issues with your legitimate email sending.
