SUUMAIL uses Google Apps for Education, a free service from Google that offers the power of Gmail, Google Calendar, Google Chat, Google Docs, and more specifically for Southern Utah University.
You do not get a Gmail address, rather you get an email address like firstname.lastname@example.org that has all of the functionality of Gmail and more.
Another key difference is how you log in to SUUMAIL. Southern Utah University's Google Apps for Education service uses our single-sign-on (SSO) service. This SSO service is used by many applications here at SUU. By signing into mySUU, you will be able to get directly into SUUMAIL without having to re-enter your username and password.
