Yeah, sleepers make up a large if not a majority of many recurring revenues. I once worked at a very popular online service where I was in charge of the payments team. We had many ways to subscribe or upgrade, but to cancel it online was possible but very difficult. The cancel option was hidden under many clicks and dropdowns. That was mandated from C-level management even though we kept imploring to allow us to make it more obvious. I think the majority instead contacted customer services to manually cancel it. Some also did a chargeback, which companies hate as it is expensive. But in the end, there were so many sleepers that every time there was a plan to email all customers about an offer, or new service, it was always raised that it might make a lot of customers aware that they have the subscription, or check with their kids if they still need it, so sometimes the mailshots were filtered to active members, or just skipped all together etc. It was an uneasy balance of "don't touch", and never felt nice. Last year I was contracted back to that company to help sunset the product I worked on years before, writing tools to notify and cancel all recurring payments. A huge chunk of customers was then sleepers that had not logged for 7-9 years. I do wonder how many were surprised when they got the cancellation email! :)
