Please save the "once the list built" <--- see, that's the catch. It's not the catch, it's not that hard to build the list (compared to making paid channels work from an ROI perspective). And in particular for ecommerce (topic of stripe article) just having a simple checkbox for anyone checking out to opt in is more or less free. Mailchimp costs compared to ad costs are also super cheap.
