I am running a zammad installed with zammad-helm 15.2.2. I have only one Google Mail Channel set up. Customer can receive emails from agent’s reply. However when one Agent @mention another agent (say B) in internal node, agent B will subscribe the ticket successfully, but will not get email about it.
Other threads indicated it’s a Notification Master configuration issue, and Manage > Channel Email> Settings were the place to modify Notification Master default value. On current version 6.5.2, there is no row to modify Notification Master there. Not sure it’s because I only have one Google Email configured, or other reason?
Is there way to modify it to sending mention notifications using Google Email channel configure?
Expected behavior:
- When Agent B is @mentioned in internal note, they should receive email notification too.
Actual behavior:
- When Agent B was @mentioned in internal note, they did not receive email notification, they only subscribed the ticket.
Steps to reproduce the behavior:
- create a test ticket by sending emails to the Google Email channel email address.
- Agent A create a internal note in the thicket, and @mention Agent B with @@ short cut.
- noticed Agent B showed up in the subscriber area after clicking Update button.
