Each UTD email account has two email addresses associated with it. The primary address, which uses the more generic NetID, in the form of email@example.com and a Personalized Email Address (PEA) which is usually in the form of firstname.lastname@example.org.
By default, outgoing email sent outside of UT Dallas will use the NetID email address in the "From" field. To make your emails more personally identifiable to non-UTD contacts, you may opt to change this default "From" address to your PEA.
If you would like to have your PEA changed, you will need to submit an Atlas self-service ticket at https://atlas.utdallas.edu. To submit an Atlas Self-service ticket:
