Any ICO project managers, community managers, or e-mail folks have any experience buying lists from websites like
https://cryptoemaillists.com/? They say they purchased from closed ICOs so they're confirmed buyers. Seems to me it's a clear path to ROI but have no idea how to think about this.
I don't understand this, are you asking for where to buy emails for sensitization of a project?, and if so how does it seem to be a good way for a better Return on investment?
