Hi, @SWyatt502.

Thank you for providing complete details of your payment receipt concern. Please note that you can only change the message manually and not permanently. We understand how inconvenient this can be, so I recommend sending a request to our developers.

We value your thoughts regarding customizing the preset email message for your payment receipt transactions, so you don't have to retype it every time. Since this is currently unavailable, consider sending a message to our product developers to help us enhance the program according to your needs. Follow the steps below:

1. Go to the Gear icon at the top.
2. Under the Profile column, select Feedback.
3. Share your suggestion, then click Next.
