To improve your deliverability, Mailchimp automatically adds default authentication to your marketing emails. Domainkeys Identified Mail (DKIM) authentication is a sender identification tool that protects email senders and their recipients from spam, forgery, and phishing.


In this article, you will find out how to enable DKIM for your domain in Mailchimp.


Before you can setup DKIM for your domain in Mailchimp, you will need to verify your domain within the Mailchimp platform. Please see this article on How to verify your domain in Mailchimp


After your email domain is verified, you will then need to enable DKIM for your domain in Mailchimp.
