Roadrunner Email IMAP Settings for 2026 (Incoming and Outgoing)
Setting up an old rr.com address on a new phone? Good news. The settings barely changed when Spectrum took over, and IMAP is the one you want.
Quick answer: The Roadrunner email IMAP settings are incoming server mobile.charter.net on port 993 with SSL on, and outgoing server mobile.charter.net on port 587 with SSL on. Sign in with your full address and your password.
I set these up constantly for people who kept their rr.com, roadrunner.com or twc.com address for years. The thing that trips almost everyone is the username. It has to be the whole address, the part after the @ included. Miss that and the app just says it cannot connect, with no clue why.
Dropping these into your mail app
- Add a new account and pick IMAP when it asks for the type. Not POP.
- Put your full Roadrunner address in as both the email and the username.
- Incoming: mobile.charter.net, port 993, security SSL/TLS.
- Outgoing: mobile.charter.net, port 587, security SSL/TLS, with authentication turned on.
- Save, then send yourself a quick test so you know both directions work.
Why IMAP over POP? Because IMAP keeps your phone, tablet and laptop showing the same inbox. Read a message on one, it shows as read on the rest. That alone saves a lot of confusion.
If the older server mail.twc.com is already saved on a device and working, leave it. It still connects for rr.com addresses. For a fresh setup, though, mobile.charter.net is the current one.
Anything to do with your actual sign-in or password gets handled on Spectrum, since Spectrum runs Roadrunner mail now. The two links worth saving are the Spectrum webmail sign-in and Spectrum’s own email settings page.
Questions people ask
Does Roadrunner IMAP work on all my devices at once?
Yes. That is the whole point of IMAP. Every device talks to the same server, so your inbox looks identical on your phone, tablet and computer.
What username do I enter for Roadrunner IMAP?
Your full email address, the part after the @ included. The first part on its own will not connect.
Can I use these IMAP settings on more than one phone?
Absolutely. Add the same account and the same servers on every device you own. Because IMAP syncs with the server, reading or deleting a message on one phone updates the others. No duplicates.
