'A new user has subscribed to you on YouTube! They don't have a YouTube channel yet, but they will still receive notifications when you upload new videos, create playlists, like videos and so on.

Subscriptions allow you to connect with other people and be notified when they upload new videos or respond to others' videos (by favoriting, commenting, rating, etc). You can control which of your actions are publicly visible by going to your Sharing settings.

You can see new activity from your subscriptions on your YouTube homepage'.
