Send reminder to inactive users?

The plugin looks really great, but I miss the feature to remind users to come back to the site, when they had not logged in over xyz days into the site! I want my Site members to remember the existence of my page and poke them to come back again.

Will there be such an add-on in the Future for this plugin, Or does anyone know anywhere else a plugin that manages such a job?

Greetings and merry Christmas to you all,

Gerrit
