Integrating AdRoll and MailChimp

Jump to:

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

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


How do I create MailChimp CRM segments?

To find the MailChimp integration tool, navigate to SettingsIntegrations. Once integrated, each list selected will populate as its own segment in the Audience tab of your AdRoll dashboard.

Activating 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 your AdRoll dashboard.

  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 segment.

  8. Save


Best Practices for MailChimp CRM Segments

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!


When will my MailChimp CRM segment(s) be ready to use in my campaigns?

Your MailChimp CRM segment may not appear on your dashboard immediately. We will begin the matching process for new lists within 6 hours. Any new emails added after the process has begun may take up to 2 weeks to be matched. All MailChimp segments will be automatically named and start with mailchimp.

After your email list appears the cookie matching begins. Give your MailChimp segment(s) up to 7 days to cookie match for both web and Facebook before adding it to any campaign(s).

Please read on for more detail on what to expect with your MailChimp segment(s).

  • Once integrated, we will pull new emails from MailChimp every 6 days, keeping your MailChimp CRM segment up to date as you work with your lists.
 Once pulled, the matching process takes up to 7 days.

  • For US advertisers, CRM can be launched on both web and Facebook. Where possible, we recommend using US-based email addresses and they match at a higher rate than non-US emails.

  • Outside of the US, CRM segments have limited functionality on web campaigns. We are working on building this functionality, but we recommend that non-US advertisers adopt CRM retargeting on Facebook instead.

  • CRM segments cannot be edited after they are created.

  • Cookie matching on Facebook will take less than a day.

  • Cookie matching on the web takes up to 7 days, depending on the size of your email list. Make sure you take this into consideration when planning your CRM campaign.


How many emails were matched?

When your segment appears in your Audience tab, 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 segment in the Audience tab. 

  • Total Web Visitors: Total active cookies matched for web.

  • New Web Visitors: Cookies matched within the date range specified.

  • Total Facebook Visitors: Total active cookies matched for Facebook.
