Using Zapier to push MailChimp unsubscribes to ChartMogul

Integrating MailChimp with ChartMogul is useful for analyzing 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 with custom attributes. You can then analyze how many customers are unsubscribing from your newsletter and their revenue contribution to determine whether to adjust your newsletter content and communication.

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