The Broadcast List feature allows you to send a message or media to several contacts at once. The broadcast message will appear to be an individual message from you. Broadcast message requirements: Make sure all the contacts in the Broadcast list have saved your number in their address book.
WhatsApp Group is similar to a group of friends sitting in a room where everything you say or hear can be heard by other people in the room as well. A WhatsApp Broadcast allows you to send a message or media to several contacts at once. The message sent by you will appear as an individual message in the chat.
When you send a message to the broadcast list, it’ll be sent to all recipients in the list who have your number saved in their phones’ address book. Recipients will receive the message as a normal message. When they reply, it’ll appear as a normal message in your CHATS screen.
