Will I Loose My Email Address If I cancel ATT Land Line Services?

Hello.

A number of years ago I had ATT DSL as my ISP. I was furnished with an email address @sbcglobal.net in conjunction with Yahoo!

To this day I use this email address, although I am now using a different ISP. However, I am still a customer of ATT through my land line service. Now, because of costs per month, I need to stop my ATT landline service.

My question to the community is: If I cancel my ATT landline service and no longer use ATT services, will my @sbcglobal.net email address be lost?

Thanks.
