Jira not sending automated emails

[Deleted user]

No automated emails are being sent for 3 Jira subscriptions I have. 

http://jira.vanguard.com:8080/secure/EditSubscription!default.jspa?subId=14502&filterId=31500

http://jira.vanguard.com:8080/secure/EditSubscription!default.jspa?subId=13304&filterId=28047

http://jira.vanguard.com:8080/secure/EditSubscription!default.jspa?subId=17111&filterId=40711

In addition, I'm not receiving an automated email with someone tags me in a Jira comment. Even as a system admin of jira within this enterprise i am not able to see these subscriptions. it says no permission.
