Does your extension have Stripe email receipt?
I know that Stripe is able to send email recepts: stripe.com/docs/dashboard/receipts
But I decided to send standard Magento 2 email recepts to the customers instead of the Stripe’s ones.
If you really need to send email recepts from Stripe, I can implement it as a paid feature: see my payment extension customization service.
But I think the standard Mageto 2 email receipt is enough.
