Conversations allows you and your members to contact each other directly, outside of the group communication. Your members can use Conversations if they are allowed to see each other in the Member Directory (see How can I control member privacy). You and your members can also create conversations with more than one other person.
You and your members can also access this by clicking on Send message from a profile.
Recipients can see conversations on the web platform, in the mobile app, and via email. They can reply back in any of those three places, or they can unsubscribe from that conversation if they choose.
NOTE: Personal emails aren't exposed via Conversations.
