Comcast switched off its email app in 2021 and never replaced it
Xfinity Email App: a Comcast Email App for Windows and Mac With Every Account in One Inbox
There is no Xfinity email app to download. Inboxes opens your Comcast.net mailbox over IMAP on any computer, beside Gmail, Yahoo, iCloud and your own domain.
imap.comcast.net · Xfinity ID sign in · Nothing to install
In short
There is no Xfinity email app, and there has not been one since April 20, 2021, when Comcast discontinued Xfinity Connect and folded Voice2Go with it. Email never went into the Xfinity app that replaced it, so the app on your phone today pays your bill and reboots your modem but will not show you a message. What Comcast offers instead is the website at connect.xfinity.com and a published set of server settings: imap.comcast.net on port 993 with SSL for incoming mail, smtp.comcast.net on port 587 for outgoing, and your full Comcast.net address as the user name. One thing has to happen first, and it is the reason most setups fail on the first try. Comcast keeps a checkbox called Third Party Access Security, and if you were not already using an email program it starts switched off, so clients are refused before your password is even checked. Tick it under the gear icon, Settings, Security, and any IMAP client connects. There is a second wrinkle in 2026: Comcast is moving Comcast.net mailboxes onto the Yahoo Mail platform in phases, and once yours has moved the servers change to imap.mail.yahoo.com and smtp.mail.yahoo.com. Both sets of settings are below.

What Comcast publishes, and what it quietly stopped publishing
Which Xfinity email apps actually exist
Most results for this search were written while Xfinity Connect still existed, or by sites hoping you will download an installer Comcast does not make. Here is the current state of it.
Xfinity Connect was the email app, and Comcast switched it off. It went on April 20, 2021, in what Comcast described as an effort to streamline its apps. That is the whole answer to the question most people are actually asking. You are not failing to find the app. It was withdrawn five years ago and nothing took its place, which is unusual: most providers in this position at least kept a webmail shortcut in the main app.
The Xfinity app you can install today has no mailbox in it. It handles your account, your bill, your plan, outage updates and your equipment. Comcast has not added email to it and shows no sign of doing so. If you installed it hoping to read Comcast.net messages, that is the moment most people end up on a page like this one.
Comcast tells you to use somebody else's program, and that is official advice. Its support article is titled Set up your Xfinity Email address with an email program, and it lists Outlook, Apple Mail on Mac OS, iPhone or iPad, Android devices, the Samsung Email App, the Gmail App, the Windows Mail App and Mozilla Thunderbird. This is not a workaround. It is Comcast documenting how to read your mail in software Comcast did not write.
Two entries on that list no longer work the way the article implies. The Windows Mail App is the obvious one: Microsoft retired it at the end of 2024, so a Windows user following Comcast's own instructions arrives at an app that is gone. Google is also closing the route that lets the Gmail app collect mail from other providers, which takes another name off the list in January 2027. Comcast's recommendations are quietly aging out from underneath it.
One checkbox decides whether any of this works. Comcast added a setting called Third Party Access Security, and its behavior is the single most useful thing on this page. If you were already using an email program when it was introduced, it is ticked. If you were not, it is unticked, and every client you try is refused. People reasonably conclude their password is wrong, regenerate it, try a different app, and get the same failure, because the problem was never the password.
Comcast is candid that it would rather you used the website. Its own article warns that third party programs can expose your Xfinity ID and password, and recommends the web portal. That is a fair thing to say, and it is worth weighing. It is also why the setting defaults to off for new users, and why the friendliest instructions on the internet for connecting a client are not the ones Comcast wrote.
POP is being narrowed, and two ports are already closed. Port 110 for POP is no longer supported and Comcast directs you to 995 with SSL instead. Port 25 for outgoing mail is not supported either. If you have an old client that has been quietly failing to send for a while, one of those two is usually why, and the fix is to move it to IMAP on 993 and SMTP on 587.
Your mailbox may be moving to Yahoo, and that changes every server name. Since June 2025 Comcast has been inviting Comcast.net customers to move onto the Yahoo Mail platform at no extra cost, rolling out in phases through 2026. Your address does not change and your mail, folders and contacts come with you. What does change is the plumbing: imap.comcast.net stops being the right answer and imap.mail.yahoo.com becomes it. Accepting is optional, and it cannot be undone.
Nothing Comcast makes will show a non Comcast mailbox. The Xfinity Email website shows Comcast.net and only Comcast.net. If your day runs across a Comcast.net address you have had for twenty years, a Gmail you actually use, and something for work, Comcast has no product that puts them in one list, and after the Yahoo move it still will not. That gap is why this search exists.
Every way to read a Comcast.net mailbox on a computer
Seven routes to Xfinity email on a desktop, compared
The column that decides this is rarely the feature list. It is whether the thing runs on the machine in front of you, and whether it can hold your other addresses at the same time.
Swipe to see all columns →
| Route to Comcast email | Runs on | Holds other accounts too | Needs the Third Party Access box | Cost |
|---|---|---|---|---|
| Inboxes | Windows, macOS, Linux, ChromeOS, in a browser tab | Yes, one merged board | Yes, tick it once | 29 dollars a month flat, five mailboxes |
| Xfinity Connect app | Nothing. Withdrawn April 20, 2021 | Not applicable | Not applicable | No longer distributed |
| Xfinity Email website | Any browser, any machine | No, one Comcast.net mailbox | No, it is Comcast's own portal | Included with your internet service |
| Windows Mail App | Retired by Microsoft at the end of 2024 | Not applicable | Not applicable | Still listed in Comcast's own instructions |
| New Outlook | Windows and macOS | Yes, several accounts in one window | Yes | No license fee, paid tiers via Microsoft 365 |
| Thunderbird | Windows, macOS, Linux, Android | Yes, through Unified Folders | Yes | Open source, no license fee |
| eM Client | Windows and macOS only | Yes, one folder tree | Yes | 59.95 dollars once for one device, or 39.95 a year |
Comcast facts checked against Xfinity's own support pages in September 2026, including the article Set up your Xfinity Email address with an email program and the article on turning third party access on or off. The Xfinity Connect retirement date of April 20, 2021 comes from Comcast's own support statements at the time. Thunderbird and new Outlook both hold several accounts and cost nothing, and if one merged list is your entire problem they are honest answers. eM Client prices checked on the US version of its pricing page in September 2026: 59.95 dollars once for a single device, or 39.95 dollars a year. Its euro list is cheaper, which is why quoted figures for that product vary so widely.
Comcast email IMAP settings and Xfinity email settings
What to type into any mail client
Two sets of values, because 2026 is a transition year. Use the left column if your mailbox is still on Comcast, and the right one if you have accepted the move to Yahoo Mail.
| Setting | Still on Comcast | After the move to Yahoo Mail |
|---|---|---|
| Incoming server (IMAP) | imap.comcast.net | imap.mail.yahoo.com |
| Incoming port | 993 with SSL on | 993 with SSL or TLS |
| Outgoing server (SMTP) | smtp.comcast.net | smtp.mail.yahoo.com |
| Outgoing port | 587, or 465 if needed | 465 or 587, SSL required |
| User name | Your full Comcast.net address | Your full Comcast.net address |
| Password | Your Xfinity ID password, but only after the access box is ticked | A Yahoo app password if the old one is refused |
| Where you sign in on the web | connect.xfinity.com | login.yahoo.com |
Comcast values are the ones Xfinity publishes for other email programs, including its note to choose STARTTLS if your client asks for an authentication method, and its warning that POP port 110 and SMTP port 25 are no longer supported. The Yahoo column comes from Yahoo's own help page for Comcast.net accounts moving to Yahoo Mail, which tells you to finish the move and sign in at login.yahoo.com before you reconfigure any client, then re add the account using the Yahoo details. Checking which set applies to you takes a second: if connect.xfinity.com still opens your mail, you are on the left column.
Setting it up
Comcast email in a desktop app, in four steps
The whole job is one checkbox and one server name. Nothing gets installed, and no Comcast software is involved on the machine you are sitting at.
Step 1
Tick the access box
Sign in to Xfinity Email with your Xfinity ID. Click the Gear icon in the top right, then Settings, then Security, and check the box under Third Party Access Security. Skip this and nothing else on the list will work.
Step 2
Add the mailbox
Enter your Comcast.net address and your Xfinity password. The server is imap.comcast.net on port 993 with SSL, and outgoing is smtp.comcast.net on 587. If you have moved to Yahoo, use the right hand column above instead.
Step 3
Add the rest of them
Gmail, Yahoo, AOL, iCloud, Zoho and anything at your own domain join the same board the same way. Each row shows which account it arrived on, so a merged list never leaves you guessing where to reply from.
Step 4
Let the sorting run
Each message gets a category and a spam verdict as it arrives, across every connected mailbox at once. Comcast rules only ever see the Comcast account, which is the ceiling on doing this inside one provider.
Where a browser client fits
What you actually get here
The pitch is deliberately narrow. This is not a nicer Xfinity Email, it is the job no Comcast product does, which is holding every mailbox in one list.
Comcast beside everything else
Your Comcast.net address in the same stream as Gmail, Yahoo, AOL, iCloud and your own domain, sorted by arrival with the source account on each row. Xfinity Email shows Comcast and only Comcast.
It survives the Yahoo move
If your mailbox migrates, you change two server names and carry on. The board does not care which platform is behind the address, because it talks IMAP to whichever one is answering today.
No installer to vet
Comcast distributes no mail application, so every download page offering an Xfinity Connect installer is shipping something else. A browser board removes the question, because there is no executable in the picture.
It opens on any machine
Windows, macOS, Linux and a Chromebook all load the same board in whatever browser is already there. The desktop at home and the laptop you travel with show an identical inbox with no second setup.
A twenty year old address, finally readable
Long lived ISP mailboxes collect a decade of receipts, statements and account resets. Sorting arrives on all of it at once rather than one folder rule at a time inside a portal you visit twice a week.
Sorting across all of them at once
A category and a spam verdict land on each message as it arrives, on every connected account. Provider rules stop at the provider boundary, which is why four mailboxes usually means four separate sets of filters.
Where this is the wrong answer
What Inboxes does not do
It will not connect a Microsoft mailbox. We authenticate with a user name and a password. Microsoft has removed basic authentication from Exchange Online and intends to rely only on OAuth for Outlook.com too, so an outlook.com, hotmail.com or Microsoft 365 work address will not connect here. Comcast, Gmail, Yahoo, AOL, iCloud, Zoho and own domain mailboxes all do.
It cannot stop the Yahoo migration or reverse one. That is between you and Comcast, and Comcast is clear that accepting the invitation is a one way door. What we can do is keep working either side of it, since both platforms are ordinary IMAP.
No calendar, no contacts, no voicemail. We are a mail client and nothing else. Xfinity Connect used to carry Voice2Go alongside email, and nothing here replaces that half of it.
There is no offline mode. It runs in a browser tab and wants a connection. Thunderbird and eM Client both keep a local archive you can read on a plane. If that matters, keep one of them for your main account.
There is no permanent tier that costs nothing. Plans start at 29 dollars a month flat for five mailboxes. The Xfinity Email website is included with your internet service, new Outlook carries no license fee and holds several accounts, and Thunderbird carries no license fee and merges accounts through Unified Folders. If one combined list is the entire problem and installing desktop software suits you, use Thunderbird. The case for paying starts when the volume itself is what you are trying to shrink.
FAQ
Questions people ask about the Xfinity email app
Does Xfinity have an email app?
No. Comcast retired the Xfinity Connect app on April 20, 2021 and has never put email into any other Xfinity app. The Xfinity app you can install today handles your account, your bill and your internet service, not your mailbox. The supported routes are the web at connect.xfinity.com or any third party email program connected over IMAP.
Does Comcast have an email app?
Not one of its own, and this catches people out because Comcast used to. Xfinity Connect was the email app and it was switched off in April 2021. What Comcast does instead is publish IMAP and SMTP settings and tell you to use an email program. So the app you end up with is somebody elses, pointed at imap.comcast.net.
Is there a Comcast email app for Windows?
Not from Comcast. Its own setup article still lists the Windows Mail App as an option, but Microsoft retired that app at the end of 2024, so that route is gone too. On a PC today your choices are the Xfinity Email website, new Outlook, an installed client like Thunderbird or eM Client, or a browser based board that holds your other addresses at the same time.
What happened to the Xfinity Connect app?
Comcast discontinued it on April 20, 2021, saying it wanted to streamline its apps. Voice2Go went with it. Comcast pointed customers at the browser for email and told anyone who wanted email on a phone or a desktop to set up a third party program instead. Nothing has replaced it in the five years since.
What are the Comcast email IMAP settings?
Incoming mail is imap.comcast.net on port 993 with SSL on. Outgoing mail is smtp.comcast.net on port 587, with 465 as the fallback, and encryption set to TLS. If the client asks for an authentication method, Comcast says choose STARTTLS. Your user name is your full Comcast.net email address. Port 110 and port 25 are no longer supported.
Why is my Comcast email not working in my email app?
Nine times out of ten it is one checkbox. Comcast has a setting called Third Party Access Security, and if you were not already using an email program it is switched off, so every client is refused before it reaches a password check. Sign in at Xfinity Email, click the gear icon, choose Settings, then Security, and tick the box under Third Party Access Security.
How do I allow third party email programs in Xfinity?
Sign in to Xfinity Email with your Xfinity ID and password. In the top right corner click the Gear icon, then select Settings. Click Security. Then check the box under Third Party Access Security to allow access. Comcast notes that if you do not currently use a third party program the setting starts unchecked, which is why a brand new setup fails.
Do I need an app password for Comcast email?
On the Comcast platform, no. You use your Xfinity ID and your normal password once Third Party Access Security is ticked. That changes if your mailbox has been moved to Yahoo Mail: Yahoo may reject your old password in a mail client, and you then generate an app password inside Yahoo account security and paste that instead.
Is Xfinity email becoming Yahoo?
For many customers, yes, but only if you accept it. Since June 2025 Comcast has been inviting Comcast.net users to move their mailbox onto the Yahoo Mail platform at no extra cost, in phases that continue through 2026. Your address stays the same and your messages, folders and contacts come with you. The move cannot be reversed once you accept the invitation.
What are the Comcast email settings after the Yahoo move?
They change completely, which is why old guides stop working. After the migration, incoming mail is imap.mail.yahoo.com on port 993 with SSL or TLS, and outgoing mail is smtp.mail.yahoo.com on port 465 or 587 with SSL required. You sign in at login.yahoo.com using your full Comcast.net address, and you may need a Yahoo app password.
Is Xfinity ending its email service?
Comcast is not shutting Comcast.net addresses down, it is moving the platform underneath them to Yahoo Mail. The address survives. What is genuinely ending is the idea that Comcast will ever build you an app for it, and if you leave Comcast as an internet customer, keeping the mailbox depends on Comcast policy rather than on anything you control.
What is the best app for Comcast email?
It depends on how many mailboxes you have. If Comcast.net is the only address you check, the Xfinity Email website is adequate and costs nothing, and Thunderbird is a solid installed client. If you also carry a Gmail address and something at your own domain, the deciding feature stops being the reader and becomes whether all of them land in one list.
Is there an Xfinity email app for PC?
Not one published by Comcast. Any download page offering an Xfinity Connect installer for Windows is distributing something Comcast does not make, because the real app was withdrawn in 2021 and never reissued. Treat those results as a security problem. The legitimate routes are the website, an IMAP client you choose yourself, or a browser board.
Can I use Comcast email on Windows 11?
Yes, but not with anything that ships in the box. Windows 11 no longer includes the old Mail app, which Microsoft switched off at the end of 2024, so there is nothing built in to point at Comcast. Use new Outlook, an installed client, or open a browser based board that works the same on Windows, macOS and a Chromebook.
Can I read Comcast email and Gmail in one app?
Yes, in any client that speaks IMAP, and it is the usual reason people go looking for one. Xfinity Email shows Comcast. Gmail shows Gmail. A third party client signs into Comcast with your Xfinity ID and into Gmail with an app password, then presents both in a single list sorted by arrival with the source account on each row.
Where do I download the Comcast email app?
There is nothing to download, and it is worth knowing that before clicking a result that offers one. Comcast withdrew Xfinity Connect in 2021 and distributes no mail application for Windows, macOS or Linux. Sites advertising a Comcast email installer are not shipping Comcast software, so the safe answer is a browser or a mail client you already trust.
Can I keep my Comcast.net email if I cancel Xfinity?
Do not assume so, and check before you cancel rather than after. Comcast has historically tied continued mailbox access to having used the address recently, and the terms are Comcasts to change. If a Comcast.net address is on your bank, your utilities and twenty years of receipts, connect it to a client you control and start moving the important accounts to an address nobody else can switch off.
