Set up Cox.net
in any email app.
The correct IMAP, POP3 and SMTP settings for Cox.net. Use these with BlueMail, Outlook, Apple Mail, Thunderbird or any other mail client.
Instead of using Cox.net's webmail interface, you can use a mobile or desktop email app like BlueMail, Outlook, Apple Mail or Mozilla Thunderbird. Desktop email apps offer more features, faster access and offline reading. Your messages are right there even without a connection.
How to set up Cox.net in BlueMail
- Get BlueMail. Install BlueMail free on iOS, Android, Mac, Windows or Linux, or open web.bluemail.me in your browser.
- Add your account. Open BlueMail and tap Add Account, then choose Email.
- Sign in with your Cox.net address. Enter your full Cox.net email address and password.
- Let BlueMail find the settings. BlueMail detects the correct Cox.net servers automatically. If you're asked to enter them manually, use the settings below: incoming imap.mail.yahoo.com and outgoing smtp.mail.yahoo.com exactly as listed.
- Done. Your Cox.net inbox appears and stays in sync on every device you sign in on.
Cox email now runs on Yahoo
Cox moved all cox.net mailboxes to the Yahoo Mail platform during 2025. You keep your @cox.net address, but sign-in now happens through Yahoo and the old cox.net servers no longer apply. To use an email app, create an app password on your Yahoo Account Security page: choose App Passwords, click Generate, name your app and copy the code, then use it in place of your normal password with the Yahoo servers shown below.
