Why Email Authentication is Crucial

Authentication plays a vital role in ensuring the successful delivery of your emails through Mailchimp, functioning akin to a license plate. This process furnishes a traceable identifier that communicates to your recipient's internet service provider that you are a legitimate sender, significantly contributing to the successful placement of your emails in their inbox.

Understanding DKIM, SPF, and DMARC

DKIM (Domainkeys Identified Mail): DKIM is a sender identification tool that safeguards against spam, forgery, and phishing by adding an encrypted digital signature to email headers.

SPF (Sender Policy Framework): SPF helps detect forgery by scrutinizing the listed return-path address, reducing the likelihood of phishing attempts.

DMARC (Domain-based Message Authentication, Reporting & Conformance): DMARC utilizes SPF and DKIM to authenticate emails, providing instructions to receiving servers on how to handle messages from your domain.

Custom Domain Authentication

For those using a custom email domain, implementing DKIM authentication is essential. This allows Mailchimp to display your domain's information in the email header, improving delivery rates and enhancing the professional appearance of your emails.

Steps for Custom Domain Authentication

To set up custom domain authentication, follow these steps:

  1. Verify your domain.
  2. Edit the CNAME and DMARC records in your domain's DNS settings.

Benefits of Custom Domain Authentication

Authenticating your domain offers three significant benefits:

  1. Removal of Default Mailchimp Authentication Information: Eliminates "via
    "youremail@domain.com" or "on behalf of "youremail@domain.com" from the sender details, enhancing professional presentation.
  2. Improved Inbox Placement: Enhances the likelihood of your emails landing in recipients' inboxes rather than spam or junk folders.
  3. Alignment with DMARC: Aligns your domain with DMARC and enables the use of Brand Indicators for Message Identification (BIMI) to display your logo prominently.

Determining the Need for Custom Domain Authentication

Before proceeding with custom authentication, consider the following questions:

  1. Is your Mailchimp "From" email address associated with your email domain?
  2. Can you or your IT team access your domain's cPanel or Zone editor?
  3. Do your delivered emails currently display "on behalf of "youremail@domain.com"

If you answered affirmatively to these questions, custom authentication is recommended.

Next Steps for Custom Domain Authentication

To initiate custom domain authentication, begin by verifying your domain and subsequently edit the required CNAME and DMARC records in your domain's DNS settings. If needed, seek assistance from your website manager or domain registrar.

This is a tutorial to authenticate your domain email address for mass emails sent through Mailchimp. I do not use affiliate links inside my Mailchimp emails.

Yes, most of us are in affiliate marketing, so we can't use Mailchimp. We have to use other email autoresponder providers that allow affiliate marketing, like AWeber and GetResponse. The DMARC and DKIM can all be taken care of through SiteSupport, so they took care of it for us. Thanks for sharing that training.

You're welcome. I hope this is able to help those who do use Mailchimp for email marketing to lead their audience to their main website.
