Overview
You might wonder why some conversations that have been marked as completed or pending suddenly reopen, even without an actual response from the requester. Bounced emails trigger a status change on conversations, making it appear that a completed or pending case has been reopened by the system.
Information
In Kayako, a bounced email at the recipient's end will trigger a status change, which makes it appear that the system has reopened a completed or pending conversation even when there's no actual response from the requester.
Any situation blocking messages from being accepted at the recipient's end usually triggers a response that results in the bounced back message being received by Kayako.
Below is a sample screenshot of a bounced status in Kayako.
