Handle Bounce, Rejection, Spam, and Unsubscriptions

When an email is classified as bounced or rejected or when a user unsubscribes or marks a particular email ID as spam, CleverTap must be notified so that it does not attempt any further deliveries to that mailbox. This is considered a good practice and helps improve your sender's reputation. A good sender reputation virtually guarantees better delivery rates.

To obtain such information, you need to create a webhook. To do so:

Navigate to Settings > Webhooks from the Mandrill dashboard.
Click Add a Webhook.
Ensure to select the following from the available options:
- Message Is Soft-Bounced
- Message Recipient Unsubscribes
- Message Is Bounced
- Message Is Marked As Spam, and
- Message is Rejected.
Enter the CleverTap callback URL (from your CleverTap Email Settings section) in the Post To URL field.
Click Create Webhook.

Enable Unsubscribe Footer

Mandrill provides a default email unsubscribe template, which gives the email recipient an option to unsubscribe from the email list. When you select this option, the unsubscribe template is added at the bottom of all the outgoing emails.

Here is an example of the default unsubscribe footer of Mandrill:

Click Save.

Troubleshooting
