@AmmarAhmed You could send friendly periodical emails perhaps, if they sign up for that.
@AmmarAhmed But you are more thinking about them having any trouble at all?
If it's an app of sorts, I'd make sure that some kind of help feature is always accessible.
But as for pushing it infront of a user...
I'm not sure anyone has done that successfully.
(successfully being not annoying the user unnecessarily)
It might be worth a question on the site, if you can't find anything similar.
