To share a Playlist with others, you have two options.
You can send Playlists directly from the Playlists section of Products.
Do this by ticking the Playlist(s) you want to share and clicking Send.
Then select a Contact/List to send to and click Send Email.
Alternatively, you can also set up a PAGE which allows you to share Playlists to others by a customisable URL link.
