Everything: VGAP, RL, or otherwise
I don't know if all of you already know it, but this site allows you to create new folders and name them, like any other regular email service.
This week the two games I'm playing have become very active and I'm receiving between 4 to 10 messages every day. I discovered the folders option only today and it's very useful. If you have to find something a player told you a month ago it's easier if you order your emails by folders.
A folder for each game, or a folder for each attack front, even a folder for this specific allied.
In other hostings it's wise to use your personal email, but in PlanetsCentral it easier and better to use this service.
