The Fullname Address <firstname.lastname>@ucsb.edu is your official e-mail address for University business purposes.
The Connect Address <ucsbnetid>@ucsb.edu is what you use to log into Connect. Although this is a deliverable email address, most individuals opt to use their fullname address.
Some individuals may optionally also have a Departmental Address <userid>@<dept>.ucsb.edu, although these are considered a legacy service that we provide for continuity of email delivery.
Each of these addresses delivers to the same Connect Inbox.
