There’s usually a time when you send a ticket reply to your customer, and then you hear nothing back. After a while, you contact the user directly, just to receive the classic “I never got the email!” response. Now, if your user does not return in a timely fashion, you can now click a single button to re-send the exact email they received the first time.
When viewing a ticket message / reply, simply click the “Re-send Email Notification” button. That’s it!
