Through our MailChimp integration, you can sync your MailChimp email lists directly from your account to AdRoll. Matched through our CRM data onboarding process, this integration helps you easily convert your lists into a targetable audience.

Please note that you must have at least 100 unique user emails in each of your lists for the CRM lists to successfully populate.

Sync MailChimp CRM Audiences

To find the MailChimp integration tool, navigate to your Website Audience tab > Connected Audiences. Once integrated, each list selected will populate as its own audience in the Website Audience tab.

Activate the MailChimp Integration:

  1. Navigate to Integrations.

  2. Click Sync segments from MailChimp.

  3. Check the box to Sync MailChimp emails to AdRoll. A field to enter your MailChimp API Key will appear.

  4. Click here and enter your MailChimp username and password to gain access your unique MailChimp API key, which you need to complete this integration.

  5. Copy the key and then return to AdRoll.

  6. In Integrations, paste your MailChimp API Key into the corresponding field.

  7. Click Select Lists to specify which (or all) lists you want to import as a CRM audience.

  8. Save.

Best Practices

To learn how to create and manage your lists within MailChimp, click here. Below we outline some tips and considerations to take when preparing your lists for CRM data onboarding.

  • Your lists should contain at minimum 100 emails for best performance.

  • Use personal emails when possible, as they match at a higher rate.

  • Make sure your email database is up to date—adding an email validation step during signup workflows can be very helpful to make sure that users are supplying active emails.

  • Consider combining CRM segments with other types of segments (link to other segment articles) to boost performance. Remember, the larger the audience your campaign has, the more optimization we can perform!

Waiting for Imported Audiences to Appear

Your MailChimp CRM audiences may not appear in AdRoll immediately. We'll begin the matching process for new lists within six hours. Any new emails added after the process has begun may take up to two weeks to be matched.

Imported audiences names will automatically end with MailChimp.

After your email list appears, the cookie matching begins. Give this up to 72 hours to activate fully on your campaigns.

What to Expect Once Integrated

  • We'll pull new emails from MailChimp every 24 hours. Once pulled, the matching process may take up to 72 hours depending on the size of the list.
  • For US advertisers, CRM can be launched on both web and Facebook. Where possible, we recommend using US-based email addresses.
  • Outside of the US, CRM audiences have limited functionality on web campaigns. We recommend that non-US advertisers adopt CRM retargeting on Facebook instead.

  • You can't edit a CRM audience once it's created.
  • Cookie matching on Facebook takes less than 24 hours. 

  • Cookie matching on the web takes up to seven days, depending on the size of your email list.

Matched Emails

We'll display the number of emails originally uploaded through the MailChimp integration.

To see how many emails were successfully matched for Web or Facebook, click on the name of your MailChimp audience in the Website Audience tab.
