I run a small SaaS and it's surprising how many people never even use the service (over 20%). It's a small service that runs for cheap, so we don't have a ton of engagement/nagging emails, but we do send a monthly email when the card is charged (with an easy link to cancel). And lots of people still don't cancel. So now it's in our monitoring, at least for now, and we try to reach out when we spot non-users. I figure it's maybe great financially, but it's not great for the service (if they're not using it, they're not promoting it)
