Can my Customers receive an automated email receipt for successful transactions?

For your customer to receive an automated receipt for successful transactions, you will need to go to your Authorize.Net account settings.  

Go to: https://account.authorize.net/ and Login to your account > From the Home Page > Account > Settings > Transaction Format Settings > Email Receipt > Enable Email Confirmation > Check 'Email Transaction Receipt to Customer'  

*Please be sure that you have the correct email address on file for the client.  If you want your EzSchedule/ARB customers to receive email receipts as well, be sure to click on the checkbox next to 'Email Customer for each Successfully Authorized ARB Transaction'
