TWC Email Server Settings (IMAP and SMTP)

ByEmail Support

Here’s the full set of servers for a twc.com address, ready to copy into whatever app you’re configuring.

Quick version: Incoming and outgoing both run on mail.twc.com, port 993 for incoming and 587 for outgoing, SSL switched on, with your full twc.com address as the username.

Entering them

  1. Add a new account and pick IMAP when asked for the account type.
  2. Use your full twc.com address as both the email address and the username.
  3. Incoming: mail.twc.com, port 993, SSL/TLS.
  4. Outgoing: mail.twc.com, port 587, SSL/TLS, with authentication enabled.
  5. Save, then send yourself a message to confirm both directions work.

If an app flatly refuses mail.twc.com, swap it for mobile.charter.net. That’s the server Spectrum uses now, it takes the same ports, and it works as a straight substitute for legacy addresses. Worth knowing before you start pulling the setup apart.

Questions people ask

Which port does TWC use for sending?

Port 587 with SSL and authentication. Port 25 is blocked on most networks, so avoid it.

Do TWC and Spectrum share settings?

They’re interchangeable in practice. TWC mail uses mail.twc.com, and Spectrum’s mobile.charter.net works too on the same ports.

What username should I enter?

The whole address, including everything after the @. Just the first part won’t authenticate.

Do I need different settings for sending and receiving?

Same hostname either way, different ports. Incoming runs on 993 and outgoing on 587, both with SSL, and both authenticate with the same address and password.
