Universal Email doesn't appear in eCart's Checkout Wizard

I am a SuperSuite owner, and I have the current versions of both eCart and Universal Email installed and authorized in DW. The getting started guide says that if you have UE installed alongside eCart, you should be presented with options during the Checkout Wizard to specify how you want email to be sent from your site.

But when I go through the Checkout Wizard, I don't get any UE options at all -- it's as if eCart doesn't acknowledge that UE is installed. Is there somewhere I have to specify that I want to use UE? Is there PHP code that needs to be present on the checkout page that causes eCart to look for UE?

Thanks,

What payment gateway are you using?

I am still in the early testing stages, but I'm planning to use PayPal standard. And with that, I think I've answered my own question -- that UE doesn't work with PayPal Standard because the emails are sent by PayPal.

...but that raises a separate issue. If I'm trying to sell digital downloads, I still need to be able to send some sort of a confirmation email with a link to the download page. I am under the impression that that's ordinarily accomplished in the receipt that's sent to the user after a purchase. If I'm using PayPal Standard, how do I accomplish that?

Thanks,

You will need to create an IPN page to do this. Read about IPN on paypal and this forum to help you get started.
