Retain Email Address when cancelling internet

Investigating---my employer is willing to provide me with a different internet service (paid by them). Before you ask--I did inquire about them paying for my current account, not an option.

My question:  If I cancel my internet, but keep my cable service (tv), will I be able to retain my email addresses?  I've had the same email addresses for close to 30 years, and I wish to retain the two of them. 

Thanks in advance.
