At Last! When an email comes in from a customer and it is related to an already existing case, you can simply attach it to that case instead of opening a new case or closing it out.
This allows you to keep all related emails together.
To see this in action, visit your Unassigned Emails and if an email might be on the same thread as an existing case, you can click the subject line to see related cases and select the one you want to link to.
Try it out, enjoy, and let us know what you think of the interface!
