Reply to email to add a comment in workflow
When a user responsible for a job receives an email notification that another user commented or performed an action relating to the job, now, the user can answer to the system-generated message and the reply is automatically added as a comment to that job. You can also reply to a group.
Note
For the time being, it's only possible to reply to the original comment, not to a reply.
Email notification
When everything has been set up, you can create a job based on the preset, and you receive a notification, the notification subject is followed by an activity ID. When you answer to the notification it is automatically added as a comment to the job.
