I agree with you. But I would say that if a client is cancelling, it is fair to try and ask them why they didn't want to use the app. This helps improve the product and for a small SAAS, this kind of feedback is golden. Here is what we do usually. If a client asks to cancel, we will send them a confirmation email saying that account is cancelled but if there is any feedback they can give to help us improve, we will appreciate that. Almost 90% of the time, clients do give feedback when we do this. But thats all. No more second email or a barrage of newsletter emails.
