I had my email stolen in such an attack, i still get random "you abandoned your cart!" Emails now and then, but luckily (?) they got my credit card at the same time and i cancelled it within minutes. So it's a little annoyance, but it doesn't really make sense to me that the flood works. At least not with American credit cards that are routinely flagging my own trips to microcenter lol

Editing to add: almost 100% of these emails came from the same e-commerce product, I'll have to look up which. But every site i got an email from was running the same off the shelf template.
