Add to e-mail list box, on receipts?

[CarolA]

Hi. I'm using the "add to e-mail list box" on my checkout page. If they check it, I don't see that on either receipt - to the customer (I'm using plain text), or the notification to our store. I thought when testing that I had seen it, but maybe I was thinking of viewing the Order through "orders" instead. I searched in the help and found nothing. I searched in here, and it sounds like it doesn't show anywhere except in "Orders", but I wanted to confirm that before I gave up. I do see that I can put it on the customer receipt if I'm using HTML.

If I can just do it with HTML, does anyone have feedback on whether they feel comfortable using HTML these days for customer receipts? Maybe everyone can get and read HTML these days, but I was worried about that.

By the way, my ShopSite store is live! Thanks for everyone's help here.
