I like how easy it is to follow, comment and close the tasks on Asana: - They send an email with the full comment/update made on the task - Reply to the email to send a comment and it will update Asana - There is a direct link in the email to “View and edit” the task or to unfollow it. - You can reply with “complete” to mark the task completed - You can assign the task to a teammate by adding him to the email “to” field. All this without leaving Gmail.
