Select the check boxes next to the people you would like to message then select the settings wheel button > "Mass Communication"
Then select if you would like to send an email or an SMS text to the selected people
You can add images, attachments, links, videos, etc. just like you would in a normal email.
You can also create lists or groups to send messages to!
