In Email This Issue for Jira, emails are queued and delivered in batch. In the past, if an email could not be delivered successfully, end-users had no feedback on the failure (except for the admin, who could check the Error Queue manually). Now, by displaying the status of the outgoing emails on the Emails tab of the Jira issue, regular users can also monitor the dispatch process and make sure if their message was sent in fact. If not, they can contact their Jira administrator to fix the issue and send the affected message(s) again via the Resend operation afterwards.
