I am currently still on TWC/Spectrum with a Roadrunner email address. In order to upgrade my services I have to switch to a Spectrum "code" according to the agent I was chatting with. Overall the services seem superior for about the same price. If I do that, will I still have my roadrunner email? It is associated with hundreds of things.
Yes you will keep your existing .rr email address, but as mentioned, you really should consider migrating all of your stuff to an independent email account that isn't tied to your ISP. What if tomorrow AT&T or some other ISP offered you a deal you couldn't refuse but couldn't take it because you would lose your email address.
