Integrating with Churn Buster
Churn Buster is a service which connects to your Stripe.com account and takes over email automation to try and recover users whose credit cards have expired and their payments are failing as a result. Use this link to signup for Churn Buster.
MemberPress typically recommends that you set Stripe up to cancel subscriptions after the last failed retry attempt. However, that will interfere with Churn Buster, so please follow their recommendations here instead: https://support.churnbuster.io/en/articles/2251681-recommended-stripe-billing-settings
If you still want your subscriptions to be cancelled after Churn Buster has failed to recover them, you will need to contact Churn Buster support and ask them to enable that for you.
