What does MMERGE3 must be provided mean when syncing with MailChimp?


  • When attempting to force sync your Breeze Tags with MailChimp Audiences, you may get an error message that states,"MMERGE3 must be provided - Please enter a value" 

    All this error message means is that the MERGE3 field is set to "required" in MailChimp, and must be changed.

  2. Navigate to the Audience tab.
  3. If you have more than one audience, click the Current audience drop-down and choose the one you want to work with.
  4. Click the Manage Audience drop-down and choose Settings.
  5. On the Settings page, click Audience fields and *|MERGE|* tags.
  6. In the fields in the Default value column, type the default values for your merge tags. 
  7. Clear the checkbox "Required" for MERGE3 and click on the Save button.
  8. Now attempt to Force the sync again in Breeze.
