I've been trying to order from non Amazon sites as a habit lately. A large percentage of them use the same platform, maybe it's Shopify?
During checkout, they have a checkbox asking if you also want to receive promotional emails. It's annoying that this is checked by default, but I can tolerate it to some degree since I still have the ability to opt out.
I always uncheck it. Always.
Almost without fail, I end up receiving marketing emails from these companies. (And not just followups from my purchase or even review requests, which would be bad enough.)
Do these stores' checkout pages have a section to enter your billing/shipping details on the left, and then a pane displaying what's in your cart and any active coupon codes on the right?
If so, it's almost definitely Shopify.
I know what checkbox you're referring to, and another fun thing is that if you use PayPal (or, I assume, another non-credit card payment method), it bypasses the "Sign me up for promotional emails" checkbox entirely... but it still checks it for you.
So if I check out with PayPal I have to select the PayPal option, sign in to PayPal, confirm, then in the store's checkout page go back a page to manually uncheck the box. Drives me crazy. Unchecking it beforehand does nothing.
My assumption was always that there are two separate systems at play, and once your email is entered, it gets put into some sort of cart rescue campaign..which sends...promotional emails.

I never buy from those brands again.
