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 seven days 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 takes up to seven days.
  • 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.
