I'm not sure if this is what is meant in this ticket, but we are getting bombarded with messages because there is no way of subscribing to particular updates.
I imagine something similar to JIRA's notification schemes, where a user can subscribe to particular actions when their ticket is updated, rather than blanket messages covering all updates.
We are excited to introduce updated email notification preferences and digest emails. This was an extremely popular request and something we have been working hard to deliver. You now have complete control over what emails you receive and how frequently you receive them. Check out our blog post for more details.
