James,

Did you get a custom MyGate payment module for PrintShop Mail Web made for you? Because as far as I know, we do not natively support MyGate as part of our payment modules. The supported ones are PayPal, Authorize.Net, iDeal and Moneris. You can check the Administrator guide to see which ones are supported, and get more info about the payment modules:

So unless you had a custom solution made for you to use MyGate with PrintShop Mail Web, then PrintShop Mail Web won't be able to use it. If you had a custom solution made for you, then I would contact the person who provided it and ask them your questions.
