Configure Unsubscribes

You must mandatorily add Unsubscribe Tag or enable "add Unsubscribe Footer" in your Mandrill Account -> Settings -> Sending Defaults. More details heremandrill_unsub.png
  • Selecting "None" for promotional email campaigns will lead to higher chances of being classified as spam.

Configure Bounce and Complaints 

This information is obtained by "Adding a Webhook" in your Mandrill Account -> Settings -> Webhooks and selecting events as shown below to enable tracking of unsubscribes, bounces and complaints. Also, copy the url from Moengage App Settings -> Email Settings -> Connector Configurations -> Mandrill -> Callback URL and paste it in "POST to URL" text box shown below.
