Yup. Used to do sales. People are make way better decisions async (over email) than in person or on a call. People feel pressure to say yes in the moment and then the cost of later saying no is much greater than it would have been to say no over email.
The stress and all the negatives people are posting about here is the point.
Before you demonize any company doing this... Know just about every company with a product has a sales team of some kind and they are all operating with similar models. You are being annoyed by some sales people while the sales people at your company are annoying someone else.
