A receipt is generated automatically on every payment, but delivery depends on the contact details the buyer provided. If the email never arrived, the receipt is not lost: it is part of the operation data and can be sent again.
Common causes
- A typo in the email address during checkout.
- The email landed in spam or a separate folder.
- No contact was passed at all when the payment was created.
What to do
- Find the operation in the dashboard and check which contact was recorded.
- Resend the receipt to the correct address.
- If no contact was passed, make the field mandatory in your order form.
