How to use Zapier to push MailChimp Unsubscribes to ChartMogul

Integrating MailChimp to ChartMogul is useful when you want to analyze your email communication with customers alongside your subscription metrics.

For example, if a customer unsubscribes from a newsletter in MailChimp, you could push this information to ChartMogul by adding custom attributes. You can then analyze how many of your customers are unsubscribing from your newsletter, what their revenue contribution is, and determine whether to adjust your newsletter content and communication.

If you would like to easily turn on this Zap for your ChartMogul account, login to your Zapier account and head over to then enter MailChimp and click on Try It.



If you would like to learn how to set up this Zap by yourself, then continue with this article. For a general introduction to the Zapier integration please read Integrating ChartMogul with other apps using Zapier.
