AT&T Midwest → [Services] Email address continuity question

Will my ATT email addresses continue to be active and accessible (for a period of time or how long) if I cancel ATT DSL services and move my internet provider to TWC? Currently have (1) main xxx@sbcglobal.net and two xxx@ sbcglobal.net sub accounts that we access exclusively thru the Yahoo webmail portal. Any advice is appreciated.

Yes.
