Brenau keeps emailing my TigerMail account and I am no longer a student.

We are sorry but your Tigermail account is associated to the University (@tiger.brenau.edu) and thus will automatically receive all Brenau mass communications. Since you're no longer a student, your access to the account will end one full term after graduation anyway. I would suggest simply removing the account from your mail client or mobile device if you are no longer using it.

If you want to keep your Tigermail documents or other artifacts, please see this article which shows your available options:
