.edu mail

You already have a .edu address!!! Great!
All you need to do is take your existing email, say:

bob@gmail.com

and you replace the @ with a % so bob's email becomes:

bob%gmail.com

and add @cet.edu to the end, so we end up with:

bob%gmail.com@cet.edu

Any email sent to this address will get forwarded to bob@gmail.com
