What's the difference between a group chat and a mass message?

Mass messages and group chats are similar in that you can send messages to multiple contacts or numbers at one time. Now let's talk about how they differ:

• Mass Message - Send a single message to multiple recipients, initiating separate conversations with each of them. If they respond to the message, what follows will be a 1:1 conversation with that contact. Learn more about sending mass messages here.
• Group Chat - Send a single message to multiple recipients, initiating a single conversation with all of the contacts. Any responses will be seen by the entire group. Learn more about initiating a group chat here.
