As of my knowledge up to "Friday, May 03, 2024 10:03 UTC", Spectrum no longer uses the Roadrunner email brand. Time Warner Cable, which previously owned the Roadrunner email service, underwent rebranding and transitioned its email services to Spectrum Webmail.
Existing Roadrunner email users were given the option to migrate their accounts to the Spectrum Webmail platform. This migration allowed users to continue using their Roadrunner email addresses with the Spectrum platform.
However, it is always recommended to verify the current status of
Spectrum's email services by contacting their customer support
+1-844-902-0608 or visiting their official website. Email service providers may update their offerings and policies over time, so it's best to check directly with Spectrum for the most accurate and up-to-date information regarding their email services.
