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.
Note: This change will only affect emails sent to recipients with non-UTD email accounts. Messages that remain 'internal' to UT Dallas will continue to use your NetID in the "From" field.
