There are many useful features on Facebook groups, such as chats, group documents, file uploads, photo albums, and more. One exciting feature that can make for quick communication is the ability to assign a group email address, after which you can send a message directly to that address to post on the group’s timeline. Here’s how you do it:
After you’ve created a group, select “Edit Group” via the gear icon pulldown menu. Scroll down and select, “Set Up Group Email.”
Then, just fill in the desired email address and select “Save” at the bottom.
Now, simply address a Facebook message to said email address, and it gets posted in the corresponding group.
