Turning off receipt emails from your payment processor

When a donor makes a donation on a Soapbox Engage Donations page, their credit card information is relayed to your payment gateway to process the credit card.  After the payment is confirmed, that payment gateway often times will send an email receipt to the donor.  If you wish to not have the email receipts sent to your donors, review your email receipt options with your payment gateway, most of which allow you to customize as well as enable/disable this process.
