If your emails sent through Mailchimp are not reaching the targeted recipients\u2019 inboxes, then they are most probably landing in their spam folders. One of the major issues causing this can be a missing or misconfigured DKIM setup. DKIM basically works by affixing a digital signature to every outgoing email, which helps the receiving server verify if the message was tampered with in transit.<\/p>\n\n\n\n

Without a proper Mailchimp DKIM setup, your emails may not reach the inbox. They can fail DMARC checks, lose sender trust, and perform poorly. This matters even more if you send newsletters, bulk emails, or marketing campaigns where inbox placement directly affects results.<\/p>\n\n\n\n

The good part is that the DKIM setup for Mailchimp is not complicated if you follow the steps carefully. In this guide, you will learn how to add the required DNS records<\/a>, avoid common mistakes, and check if everything is working properly so your emails land in the inbox instead of spam.<\/p>\n\n\n\n

Why DKIM Mailchimp Setup Matters<\/strong><\/h2>\n\n\n\n

Setting up DKIM for Mailchimp emails is more about email deliverability than just a technical checklist. Here is how it enhances your email marketing and communication efforts:<\/p>\n\n\n\n

Improved Email Deliverability<\/strong><\/h3>\n\n\n\n

DKIM<\/a> helps email providers like Gmail and Outlook decide whether your email should go to the inbox or the spam folder. When your email is signed with DKIM and passes verification, it shows that your message is trustworthy. This increases the chances of your emails reaching the inbox, especially for marketing campaigns and bulk emails sent through Mailchimp.<\/p>\n\n\n\n

Protects Emails From Tampering<\/strong><\/h3>\n\n\n\n

DKIM makes sure that the content of your email stays exactly the same from the moment it is sent to the moment it is received. If anyone tries to change the message during transit, the DKIM check will fail. This helps receiving servers detect tampered emails and prevents altered or suspicious messages from being delivered.<\/p>\n\n\n\n

Supports DMARC Authentication<\/strong><\/h3>\n\n\n\n

DKIM is one of the main methods used by DMARC<\/a> to verify your emails. If DKIM is not set up properly, your emails may fail DMARC checks. This can lead to emails being sent to spam or even rejected completely. A correct DKIM setup helps ensure your emails pass DMARC and maintain consistent delivery.<\/p>\n\n\n\n

Builds Sender Reputation<\/strong><\/h3>\n\n\n\n

Every email you send contributes to your domain\u2019s reputation. When your emails are consistently signed with DKIM and pass authentication, it sends a positive signal to mailbox providers. Over time, this builds trust in your domain, which leads to better inbox placement, fewer spam flags, and improved overall email performance.<\/p>\n\n\n\n

Helps with Branding and Consistency<\/strong><\/h3>\n\n\n\n

When you set up DKIM with your own domain, your emails are clearly connected to your brand. This makes them look more professional and familiar to the person receiving them. Instead of looking random or suspicious, your emails feel more trustworthy, which can lead to better engagement and fewer people ignoring or reporting them as spam<\/a>.<\/p>\n\n\n\n

Steps to Set Up DKIM for MailChimp<\/strong><\/h2>\n\n\n\n

Here is an easier step-by-step breakdown of the process of DKIM setup for Mailchimp:<\/p>\n\n\n\n

Step 1: Log in to Your Mailchimp Account<\/strong><\/h3>\n\n\n\n

Go to the Mailchimp dashboard, select Profile, <\/strong>then click Domains<\/strong>. Select the domain you want to authenticate. This is where you manage your sending domains and start the authentication process.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 2: Start Domain Authentication<\/strong><\/h3>\n\n\n\n

In the Domains section, find your domain and click on the option to authenticate it. This will begin the Mailchimp DKIM setup process and prepare your domain for adding authentication records.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 3: Select Your Domain Provider<\/strong><\/h3>\n\n\n\n

Mailchimp will ask you to choose your domain provider, such as GoDaddy, Namecheap, or others. Select your provider from the list so Mailchimp can guide you with the correct DNS settings.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 4: Go to Your DNS Settings<\/strong><\/h3>\n\n\n\n

Now, open your domain provider in a new tab and go to your DNS management or DNS zone. This is where you will add or update records for your domain.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 5: Add DKIM Records (CNAME)<\/strong><\/h3>\n\n\n\n

Mailchimp will give you two CNAME records<\/a> for DKIM. Add these records exactly as shown in your DNS settings. These records allow Mailchimp to sign your emails with DKIM, which helps receiving servers verify them.<\/p>\n\n\n\n

Manually generating DKIM records can result in some errors; it\u2019s always better to use an online DKIM record generator<\/a>. These tools help you create accurate DKIM records based on your domain and ensure there are no formatting errors before you add them to your DNS.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 6: Save Changes and Wait<\/strong><\/h3>\n\n\n\n

After adding the records, save your DNS changes.<\/p>\n\n\n\n

It may take some time for the changes to update across the internet. This delay is normal and depends on your DNS provider.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Step 7: Verify Domain in Mailchimp<\/strong><\/h3>\n\n\n\n

Go back to Mailchimp and complete the authentication process.<\/p>\n\n\n\n

Mailchimp will check your DNS records. Once everything is set correctly, your domain will show as authenticated, and DKIM will be active.<\/p>\n\n\n\n

\"\"<\/figure>\n\n\n\n

Quick Tip<\/strong>: Even a small mistake in DNS records can break DKIM. Always copy and paste values exactly and double-check before saving.<\/p>\n\n\n\n

Step 8: Verify Your DKIM Setup<\/strong><\/h3>\n\n\n\n

After completing your Mailchimp DKIM setup, it\u2019s a good idea to check if everything is working correctly. You can use the EasyDMARC DKIM Lookup tool<\/a> to verify your DKIM record. It shows whether your record is valid and helps you quickly spot any errors.<\/p>\n\n\n\n
