Trigger email after Stripe payment complete

I have a form that uses Stripe’s Link to process a payment. After the payment goes through, I want to trigger an email. I have the notifications event sent to “Payment Completed”, however, the email is never sent.

Additionally, once the payment is completed I make a POST request to an external CRM to send the form data. I’m using the gform_stripe_fulfillment action, and wondering if that’s stopping the email.

Thoughts?

Also, standard Contact Forms are sending emails, so it’s not the email config.
