Cox.net mail runs on Yahoo now, and Cox is Spectrum
Cox Email Settings, Cox Webmail App, and Cox Email App for Cox.net in One Inbox
Cox gave its mail to Yahoo, and Yahoo makes no desktop program. Inboxes opens your cox.net mailbox over IMAP on any computer, beside Gmail and your work mail, with one app password and nothing forwarded.
imap.mail.yahoo.com · IMAP 993 · Nothing to install
In short
There is no Cox email app, and there has not been a Cox mail platform since 2024, when Cox moved residential cox.net mailboxes onto Yahoo Mail. The Cox email settings for any program are therefore Yahoo's: IMAP on imap.mail.yahoo.com port 993 with SSL/TLS, SMTP on smtp.mail.yahoo.com port 465 or 587 with SSL/TLS, your full cox.net address as the user name, and a Yahoo app password instead of your normal password. That last point is why most Cox setups fail. Cox webmail is now the Yahoo Mail website, the only apps are Yahoo's phone apps, and Yahoo publishes nothing for Windows or Mac. Charter completed its purchase of Cox on August 20, 2026 and the brand is now Spectrum, but that announcement did not touch email. If you read a cox.net address alongside Gmail and work mail, an IMAP client holds all of them in one list without paying Yahoo 5 dollars a month to forward.
Where a cox.net address actually lives
Which Cox email apps actually exist
Search for a Cox email app and you get Yahoo sign in pages, settings pages still quoting the retired Cox servers, and a third party app named after Cox. Here is where a cox.net mailbox stands in 2026.
Cox left the email business in 2024. It announced at the start of the year that it would stop hosting residential email and moved cox.net mailboxes onto Yahoo Mail in waves, with customers told about 60 days before their turn. Addresses stayed the same. Messages, folders, contacts and calendar entries went across.
A cox.net address is a Yahoo account now. You sign in at Yahoo Mail with the full cox.net address. Yahoo publishes a help article just for transitioned cox.net users who read mail in Outlook, Mail on Mac or another program, and it is the source for every setting on this page.
Cox webmail is the Yahoo Mail website. It shows one account at a time. Yahoo does not make a desktop app for any computer: its Windows 10 app was discontinued, and it never made one for Mac, Linux or ChromeOS.
The phone apps are Yahoo's. The Yahoo Mail app for iPhone and Android signs in with a cox.net address. The Cox Mail app on Google Play comes from a third party developer, not from Cox or Yahoo, which is worth knowing before you type a password into it.
Every other program needs a Yahoo app password. Yahoo rejects your regular password in third party email apps. You generate an app password in Yahoo account security and use it once in the client. It survives a later change to your main password, and the only way to revoke it is to delete it.
Cox is now Spectrum, and mail was not part of that. Charter completed the Cox acquisition on August 20, 2026 and launched the Spectrum brand and pricing in Cox markets in mid September. The announcement is about internet, TV and mobile plans. Your mailbox is on Yahoo servers either way.
Every way to read a cox.net mailbox on a computer
Eight routes to Cox email on a desktop, compared
What separates them is where they run, whether they hold your other addresses at the same time, and what they cost once Yahoo's rules are applied.
Swipe to see all columns →
| Route to Cox email | Runs on | Holds other accounts too | Password it needs | Cost |
|---|---|---|---|---|
| Inboxes | Windows, macOS, Linux, ChromeOS, in a browser tab | Yes, one merged board | One Yahoo app password in total | 29 dollars a month flat, five mailboxes |
| A Cox email app | Nothing. Cox publishes none | Not applicable | Not applicable | Not distributed |
| Yahoo Mail website (Cox webmail) | Any browser, any machine | No, one account at a time | Your normal password | Standard plan, or Yahoo Mail Plus at 5 dollars a month |
| Yahoo Mail app | iPhone and Android only | Yahoo accounts, not Gmail or work mail | Your normal password | Standard plan |
| Forwarding cox.net into Gmail | Yahoo settings | Yes, by copying the mail across | Not applicable | Needs Yahoo Mail Plus, 5 dollars a month |
| Apple Mail | macOS only | Yes, All Inboxes | Yahoo app password | Included with macOS |
| Thunderbird | Windows, macOS, Linux | Yes, through Unified Folders | Yahoo app password | Open source, no license fee |
| eM Client | Windows and macOS only | Yes, one folder tree | Yahoo app password | 59.95 dollars once for one device, or 39.95 a year |
Settings and the app password rule come from Yahoo's article for cox.net users who read mail in a third party client. Yahoo Mail Plus pricing and features are from Yahoo's own Plus page. The acquisition date is from Charter's August 20, 2026 announcement. eM Client prices are from the US version of its pricing page. Apple Mail and Thunderbird both hold several accounts at no license fee, and if one combined list on one computer is the whole problem, either is an honest answer.
Cox email settings for any client
Cox mail server settings to type into any program
These are the values for a cox.net address that has moved to Yahoo, which is every residential cox.net address. Anything still quoting a cox.net server name is describing the platform Cox switched off.
| Setting | Value | Notes |
|---|---|---|
| Incoming server (IMAP) | imap.mail.yahoo.com | Port 993 with SSL/TLS |
| Incoming server (POP) | pop.mail.yahoo.com | Port 995 with SSL/TLS. Use IMAP if you read mail on more than one device |
| Outgoing server (SMTP) | smtp.mail.yahoo.com | Port 465 or 587, with SSL/TLS |
| Outgoing authentication | Required | Same user name and app password as incoming |
| User name | Your full cox.net address | [email protected], not a Yahoo address |
| Password | A Yahoo app password | Your normal password is refused by third party apps |
| Old Cox servers | Do not use | imap.cox.net and smtp.cox.net belong to the retired platform |
If a client keeps rejecting the sign in, check two things before anything else. First, that you pasted an app password rather than the password you use on the Yahoo website. Second, that the server fields say yahoo.com. A client that was set up years ago often still has the Cox hosts saved, and it will fail with a password error even though the password is not the problem. Delete the account in the client and add it again with the values above.
Why the usual workarounds stopped working
Forwarding costs money, and Gmail fetch ends in January 2027
For years the standard advice for anyone with a cox.net address and a Gmail account was to push one into the other. Both versions of that advice have gone stale.
The first was automatic forwarding from the Cox mailbox. Now that the mailbox is Yahoo, forwarding follows Yahoo's rules, and Yahoo lists automatic forwarding as a Yahoo Mail Plus feature. Plus is 5 dollars a month. So the tidy way to get cox.net mail into Gmail is now a subscription to Yahoo, paid to move mail out of Yahoo.
The second was letting Gmail collect the mail itself through Check mail from other accounts. Google removes that fetch, along with Gmailify and Send as for third party addresses, in January 2027, and its own suggested replacement is a mail program that connects over IMAP.
Reading each account where it lives is the route left standing, and it is also the better one. Inboxes signs in to the cox.net mailbox with a Yahoo app password and to Gmail with a Google app password, and shows both on one board. Nothing is copied, you do not need Plus, and when you reply to a cox.net message it leaves from the cox.net address, so the people who have had that address for twenty years keep seeing the name they know.
Setting it up
Cox email in a desktop app, in four steps
No installer and no Cox or Yahoo software on the machine. The connection lives with us rather than on each device, so every computer you open it on shows the same board.
Step 1
Sign in at Yahoo Mail once
Use the full cox.net address. If Yahoo still shows a terms screen from the transition, accept it, because a mailbox that has not finished the move will not connect anywhere else.
Step 2
Generate an app password
In Yahoo account security choose Generate app password, name it, and copy the code. That code, not your normal password, is what every mail program needs.
Step 3
Add cox.net, then the rest
imap.mail.yahoo.com on 993 and smtp.mail.yahoo.com on 465, with the cox.net address and the app password. Gmail, AOL, iCloud and your own domain join the same way.
Step 4
Let the sorting run
Each message gets a category and a spam verdict as it arrives, across every connected mailbox. Filters you set on the Yahoo website only ever see the cox.net account.
Where a browser client fits
What you actually get here
Not a different skin on Yahoo Mail. The job neither Cox nor Yahoo has a product for, which is holding a cox.net address and every other mailbox in one list on a computer.
Cox beside everything else
Your cox.net address in the same stream as Gmail, AOL, iCloud and your own domain, sorted by arrival with the source account on each row. The Yahoo Mail website shows one account at a time.
No Yahoo Mail Plus needed
One list without paying Yahoo to forward, and without leaning on Gmail fetch, which Google removes in January 2027.
One app password, every machine
Outlook, Thunderbird and Apple Mail are set up per computer, each with the Yahoo servers and a code. Here the mailbox is connected once, so the desktop, the laptop and a Chromebook open the same board, which is also why it works as a Chromebook mail app.
Replies from the right address
A message that arrived at cox.net is answered from cox.net. Forwarding into Gmail breaks that unless you also set up Send as, which Google is removing for outside addresses.
It opens on any computer
Windows, macOS, Linux and ChromeOS all load it in whatever browser is already there. No Cox or Yahoo desktop app is needed, which is convenient, since neither exists.
Sorting across all of them
An address that has been live since the dial up years collects statements, renewal notices and newsletters nobody reads. A category and a spam verdict land on every one as it arrives, on every account at once.
Where this is the wrong answer
What Inboxes does not do
It does not change Yahoo's rules. The app password requirement, Yahoo's storage and what Yahoo keeps behind Plus all run on Yahoo servers. We connect the way Yahoo tells third party programs to connect, with an app password over IMAP.
It is not for Cox Business email. This page covers residential cox.net addresses, the ones Cox moved to Yahoo. Cox Business mail is a separate service with its own settings, so check your business account before copying anything here.
It does not use OAuth anywhere. We connect with a user name and a password or app password over IMAP, which suits cox.net perfectly and rules out others. An outlook.com, hotmail.com or Microsoft 365 work address will not connect here. Cox, Gmail, Yahoo, AOL, iCloud, Zoho and own domain mailboxes all do.
No calendar and no contacts. We are a mail client and nothing else. Yahoo Mail on the web has a calendar and a contact list, and so do Thunderbird, Apple Mail and Outlook. If you want those in the same window, use one of them.
There is no offline mode and no permanent tier that costs nothing. It runs in a browser tab and wants a connection, and plans start at 29 dollars a month flat for five mailboxes. The Yahoo Mail website and app cost nothing on the standard plan, Apple Mail comes with every Mac, and Thunderbird carries no license fee. If one combined list on one computer is the entire problem, use one of those. The case for paying starts when you read mail on several machines, or when the volume itself is what you are trying to shrink.
FAQ
Questions people ask about the Cox email app
Does Cox have an email app?
No. Cox handed its residential cox.net email to Yahoo in 2024, and a cox.net address is now a Yahoo Mail account under the old name. On a phone the official route is the Yahoo Mail app. On a computer there is no Cox or Yahoo desktop program at all, only the Yahoo Mail website or a third party email client with a Yahoo app password.
Did Cox email go to Yahoo?
Yes. Cox announced at the start of 2024 that it was leaving the email business and moved residential cox.net mailboxes onto Yahoo Mail during 2024. Addresses were kept, and messages, folders, contacts and calendar entries moved with them. You now sign in at Yahoo Mail with your full cox.net address.
What are the Cox email settings?
For a cox.net address that has moved to Yahoo, incoming IMAP is imap.mail.yahoo.com on port 993 with SSL/TLS. Outgoing SMTP is smtp.mail.yahoo.com on port 465 or 587 with SSL/TLS, and authentication is required. The user name is your full cox.net address and the password is a Yahoo app password, not your normal one.
What are the Cox IMAP settings?
imap.mail.yahoo.com, port 993, SSL/TLS on, with the full cox.net address as the user name and a Yahoo app password. The old imap.cox.net values found on many settings sites belong to the platform Cox retired in 2024 and will not connect a transitioned mailbox.
What are the Cox email settings for Outlook?
In classic Outlook add the account with manual setup and choose IMAP. Incoming server imap.mail.yahoo.com on 993 with SSL/TLS, outgoing server smtp.mail.yahoo.com on 465 or 587 with SSL/TLS, outgoing authentication on. Enter the full cox.net address and paste a Yahoo app password where Outlook asks for the password.
Why is my Cox email not working in Outlook or on my Mac?
Almost always because the program is sending your normal password. Yahoo requires an app password for any third party email app, and it rejects the regular password with what looks like a sign in error. Generate one in Yahoo account security, paste it into the client, and check the servers are the Yahoo ones rather than the old Cox hosts.
What happens to my Cox email now that Cox is Spectrum?
Nothing has changed so far. Charter completed its purchase of Cox on August 20, 2026 and brought the Spectrum name to former Cox markets in mid September, but the announcement says nothing about email, and cox.net mailboxes already live on Yahoo rather than on Cox servers. Keep the Yahoo settings. Spectrum itself stopped giving email to new customers in June 2024.
Is there a Cox webmail app?
Not from Cox. Cox webmail is now the Yahoo Mail website, and the only apps that go with it are the Yahoo Mail apps for iPhone and Android. A Cox Mail app on Google Play is published by a third party, not by Cox or Yahoo, so check the developer before giving it your password.
How do I set up Cox email on iPhone?
Two ways. Install the Yahoo Mail app and sign in with your full cox.net address. Or add it to the iPhone Mail app as another mail account using imap.mail.yahoo.com and smtp.mail.yahoo.com with a Yahoo app password. The second keeps it beside your other accounts in one Mail app.
Can I forward Cox email to Gmail?
Only by paying Yahoo. Automatic forwarding is a Yahoo Mail Plus feature, listed at 5 dollars a month, so a cox.net mailbox on the standard plan cannot auto forward. Having Gmail fetch it over POP is not a long term answer either, because Google removes that fetch in January 2027.
Can I read Cox email and Gmail in one app?
Yes, in any IMAP client. The cox.net address connects with a Yahoo app password, Gmail with a Google app password, and both appear in one list with the source account marked. Nothing is forwarded, so you do not need Yahoo Mail Plus and replies still leave from the cox.net address.
Do I need a separate app password for each device?
Yahoo lets you create several and you can use one per app. An app password stays valid when you change your main cox.net password, so deleting it is the only way to cut off a device you no longer trust. A browser based client needs one app password in total, because the connection lives on its server rather than on each machine.
What is the best app for Cox email?
It depends on how many mailboxes you read. Only the cox.net address, on a phone: the Yahoo Mail app. One address on a Mac or PC: Apple Mail or Thunderbird, both with no license fee. A cox.net address beside Gmail and work mail, on more than one computer, is where a client that holds all of them in one list earns its price.
