Do you mean in-app or push? I'd say in-app really depends on the application. As long as they're using it that's great.

But giving up push (or emails and so forth) is much tougher. It's pretty powerful to have the ability to remind people of your app when they stop using it. If you need growth and engagement that's a very powerful tool to have.

Push. That's my plight actually. There are already too many apps trying to find a place in the push notification channels. And given my stance on notifications, I am refraining myself from doing that for now. Planning on surveying my friends and family on this. They might be the right sample space.

When you know a user is likely not coming back you've got virtually nothing to lose by sending them a push or email notification. Active users don't need to get any.
