Drafts are unsent messages created and waiting to be sent. When any new message is composed, it is automatically saved every 2 minutes to drafts. It ensures that you do not lose any composed/ half-composed and unsent messages. You can also choose to save a message in Drafts by clicking ‘Save Draft’ option.
Drafts, unlike templates, are one time messages. Once a message is sent, it would be removed from drafts.
