1.) They found a fourth video, which leads to an automatic disabling of your partnership. They probably wouldn't email you specifically about it, they'd just tell you that your partnership is disabled.

2.) You didn't have enough views/subscriptions/regularly posted videos. Youtube has a criteria for who can have a partnership and who can't (it's a secret, no one knows how many views or subscriptions you need exactly).
