Facebook has long supported group messaging. If a group is created with the right people in it and for a specific purpose it’s a fantastic way to communicate with multiple people at one. If it’s created by someone who just needs to get a message out to multiple people as fast as possible it’s little more than an annoying notification for everyone involved. Thankfully you can leave a conversation but if you’re the one sending the message and would like to avoid going the group message route while still using Facebook Messenger, MessengerMerge is a Chrome extension that can help you do just that. It lets you send a message to 16 people at once without needing to add them to a group.
Install the extension and go to Messenger for Web. Click the plus button to compose a new message and a pop-up will open.
In the ‘Add Friends Here!’ field type the name of a friend you want to message and pick them out from the matching results. Go ahead and add up to sixteen.
