For example, if your email address is
email@example.com, you could use the alias
Regardless of the letters or numbers you put at the end of the + sign, the email will be sent to your Stanford email address (or Gmail or Hotmail, if you use those email providers).
So why would you use this?
Suppose you’re a professor in the Psychology department. You teach classes in psych1, psych2, and psych3. You could tell your students that your email address is:
firstname.lastname@example.org the students in Psych1
email@example.com the students in Psych2
firstname.lastname@example.org the students in Psych3
Or, you could use the email address
email@example.com when you sign up at banking sites,
firstname.lastname@example.org when you sign up for social media sites, etc.
Best part? You don’t need to sign up for anything to use this service — you can just go ahead and use it!
