MailChimp Field Deprecations - March 24th 2020

To catch up with changes made to the MailChimp API, we have deprecated fields that are no longer available in the API and have added their replacements. This specifically affects the "List Growth History" report type in Data Studio, as the field changes are linked to that. 

This will take effect on March 24th, 2020. 

The affected fields will be moved to the group "Deprecated",  will return empty (NULL) values for all queries. 

  • Existing members
  • Opt-in members
  • Imported members

These are the new fields to replace the behavior of the deprecated ones. The new fields are not one-to-one replacements for the old ones, so you will need to update your reporting to use the appropriate metric for what you need:

  • Subscribed members
  • Unsubscribed members
  • Reconfirmed members
  • Cleaned members
  • Pending members
  • Deleted members
  • Transactional subscribers

When the changes take place on March 24th, 2020, please make sure you update your queries and formulas to remove the deprecated fields or use their replacements instead. For Data Studio, you will need to refresh your data source field list per How do I Refresh Fields/Update a Connector?
