Everything is possible. It's just a question of interest. I can make it so the user can choose:
-Email every time there is a new entry
-Weekly updates
-Only special announcements (contests, games, new bird, etc)
-No emails at all
This kind of system would be a little bit of work to make so I just want to make sure it's something that will in fact bring more subscribers. Otherwise it doesn't justify the labor in making the functionality.
