While the new system is not perfect yet, new-ticket has its own notification system that is more user-centric. This means that when you see an issue, you can easily request to be notified of all changes to that issue. You can even batch up your notifications hourly, daily, or weekly.
There are improvements to be made, like notifications of all new issues, and defaulting to notifications ON when you enter an issue. Try it out and see how it works for you.
