If you are constantly sending messages to a certain group of people, we suggest that you create a group list, so that sending a message shouldn't have to be time-consuming.
To create a group of contacts, go to https://www.filemail.com/contacts or in Filemail Desktop, simply click "Contacts".
Click "Add Group" and a window will pop-up asking you to put a group name and then hit "Save"
Once a group has been created, select a specific contact with the checkbox on the left side of the contact name and then click the "Add to groups" option.
On the address bar of the Filemail app, type in the name of the group then the drop-down will show the group option. Hit the group name and you can then send a group message.
