When you want to send messages to a group of people, a handy way is to create groups to send messages to. You can create multiple groups with their own names.
Important: you can only send messages to groups through iMessage / SMS.
Here's how to make a group:
Go to 'Settings'
Go to 'Groups'
Click 'Create group'
4. Choose the recipients you want to add to the group
5. Name your group and click 'Save'
That's it! You can now send your messages to your group!
