I want to send automatic reminders for failed payments
I want to manually collect failed payments and send emails to them.
You can enable and customize the payment reminder emails by navigating to Settings-> Configure Chargebee -> configure Emails -> Go to the revenue recovery section
If dunning is enabled for online/offline payment, then go to the respective section and enable the email notifications.
If dunning is disabled or you want to manually send payment reminder emails then go to Configure Chargebee -> Configure Emails -> revenue recovery section -> 'Payment Failure' -> enable Manual payment collection failure.
To send dunning emails ensure the dunning options are enabled and configured. Click on the toggle button to enable the email reminders.
Dunning emails are available for online recurring invoices, online one-time invoices as well as offline recurring invoices.
Manual payment collection failure emails can be configured to be sent to different recipients based on your specific scenario. You can add more notifications by clicking on the 'Add Notification' button on the Payment failure settings page.
