The articles take you through the step-by-step process to configure DKIM for emails sent from your domain via MailChimp. The advantages of doing so are as follows: 

• It helps your emails to appear to come from your domain instead of MailChimp

• This increases the chances of your receivers clicking on the emails, and helps boost email deliverability

Verifying Your Domain in MailChimp

Mailchimp requires you to verify your domain before you can start with the DKIM setup. 

In order to verify your domain: 

• Log in to your MailChimp account 

• Navigate to Accounts > Settings 

• Click on Domains

• In the Manage Domains page, click on Verify Domain

• A dialog box will appear that prompts you to enter your email address to which the verification link will be sent and click on Send Verification Email

• Configure to your specified email inbox and click on the Verify Domain Access button. Alternatively, you can use the provided verification code to verify your domain.

Setting up DKIM for Your Domain

After verifying your domain, on the Manage Domains page, click on the Authenticate button.

A dialogue box will appear showing you what CNAME record you need to create and the values for it in order to have DKIM configured. It tells you to create a CNAME record for k1._domainkey.domain.com with this value:

dkim.mcsv.net

The complete record will look like this:

Publish the CNAME record in your DNS and wait up to 24-48 hours. Click on Authenticate Domain in the dialogue box to configure DKIM and complete your authentication process.
