It seems that there should be a Zap trigger for when someone cancels their subscription through the Searchie Payments Customer Portal.
There's no automatic way to remove someone from email marketing systems when they cancel they subscription.
Currently, we have to manually add or remove an audience tag. Since there's no segment change trigger or Searchie payment cancellation.
Stripe zap triggers don't provide product info to be able to trigger audience tag updates. We are limited to either a purchase or a cancellation were made.
