Message your subscribers with bulletins
Bulletins are a great way to communicate with your subscribers on YouTube. Just go to your channel, type an update, paste a video link, and click "Post Bulletin." Your bulletin will show up on your subscribers' homepage, in their Recent Activity feed.
Think of the possibilities: Want to tell your subscribers about a new musician you just discovered on YouTube? Send a bulletin that describes her music and attach her latest video. Or maybe you just watched a vlog you really liked and want to send it out to your subscribers with a note. You can even send a video link to your other YouTube channel to let your subscribers know about it. Bulletins allow you to put context around any video or simply send your subscribers a written note.
You can send bulletins from the new “Post Bulletins” form on your channel. As you type the update to your subscribers, you’ll see a preview of the bulletin appear to the right of the text field:
