Suppose you want to send a message to all your friends. Normally you would have to group all recipients into a huge group thread to do that. But when people responded to your message, everyone in the group received a notification, so your friends were probably annoyed that you started the group thread in the first place. Luckily, this is not a problem if you use WhatsApp.
The Broadcast feature of WhatsApp allows you to send messages to multiple people without first having to create a group chat. It's somewhat similar to using your email's BCC and is available for both Android and iOS so anyone can try it. The following describes the process. If you want to know more about this useful feature, just keep reading.
Sending a message
First, open WhatsApp and tap the three-dot menu button in the upper-right corner of the main screen. From there select either "New Broadcast" (Android) or "Chats" followed by "Broadcast Lists" (iOS). You will then be taken to either your list of "contacts" (Android) or "broadcast lists" (iOS). Click "New List" below if you're on an iPhone and start a new show.
In the contact list, select the people you want to include in your broadcast by simply tapping their names to add them. When you are satisfied with your selection, either tap the green check mark (Android) or press "Create" (iOS). Just enter or attach the message you want and send it.
