Yes! You can automatically send a confirmation email with a receipt anytime a customer makes a payment on your form, whether it’s with an initial entry submission or after the entry has already been submitted.
To automatically send customers a payment receipt for submitted entries:
Under the Send settings for the email, select When and set the logic to
=(Order.PaymentStatus = "Paid"). This will ensure the email will only send to the customer when their payment has been processed.
In the Include? section, tick the box next to Receipt.
Make sure to save your changes.
