Hi ArenaNet!
I love GW2 and have recruited 4 friends to play. I like to receive emails about mini expansions and major releases, but I do not want to get emails every day about what is on sale at the gem store. This will cause me to quickly unsubscribe from the newsletter email altogether.
Please do not spam unnecessarily or provide a tiered system for push emails so I can choose not to receive these sorts of messages.
Regards,
GoneFar
