“Merge Max Limit Exceeded” issue in MailChimp Integration

By | February 12, 2019

Email Marketing is one of the most effective marketing tool used to send bulk emails to Customers and prospects in business. Email Marketing is built-in feature available in Sage CRM. It easily allows to create Campaign list, email communications and send emails to Customers. With the release of Sage CRM 7.3, Mail Chimp integration has become feasible which allows to create online campaigns, send emails, and track results from and within Sage CRM.

New StuffRestrict Document View in Shared Documents tab in Sage CRM 2018 R2 onwards

For analysis purpose, we have integrated MailChimp account in our Sage CRM 2018 R3. Integration went successfully. To send emails to a group of people, we opened the group and clicked on “Send to MailChimp” button as shown in below screenshot.


After clicking on “Send to MailChimp” button, it shows notification message as shown in below screenshot.

However, on checking the notification in Sage CRM, it was showing error as “Merge Max Limit Exceeded” for MailChimp.

After lot of searching for the above said issue, we came to know that MailChimp have changed the default settings for newly created list. Previously, when a MailChimp list is created, there were no merge fields configured. It means that, when CRM integration with MailChimp was configured, integration was able to populate 30 custom merge fields as required. However, now MailChimp list seems to be configured with the merge fields by default. And Sage CRM does not allow these default merge fields to be displayed. So to remove these fields follow below steps.

  1. Login to MailChimp account.
  2. Find out the list you have configured in the integration and go to list Settings -> List fields and *|MERGE|* tags and remove all merge fields except “*|EMAIL|* or *|MERGE0|*” field as this is mandatory field and save the changes.
  3. Login to Sage CRM.
  4. Find the Group and click on “Send to MailChimp” button.

After the Mail Chimp integration process is completed, a notification can be seen that the group of peoples are added successfully as shown in below screenshot.
