Set Up Comcast Email on iPhone: What Changed
Last updated July 23, 2026
You can read Comcast email on iPhone in two ways: add the account to the Apple Mail app, or sign in through a web browser.
One thing has changed, and it decides which steps you follow. Comcast is moving @comcast.net accounts to Yahoo Mail, in phases, across 2025 and 2026.
If your account has not moved yet, you set it up with Comcast’s own mail settings. If it has moved, you set it up as a Yahoo account. Here is how to tell, and how to do each one.
The old Xfinity Connect email app no longer exists, so do not go looking for it in the App Store.
First, check if your email moved to Yahoo
Comcast sends a notice about 30 days before it moves your mailbox to Yahoo. The move is optional, but once you accept it, it cannot be undone.
Here is the simple test. If you have accepted a Yahoo invitation, or you can sign in to your comcast.net address at Yahoo, your email now lives on Yahoo.
If you still read your mail at the Xfinity site and have never accepted a Yahoo move, you are on Comcast’s system. Follow the Comcast steps below.
Before you start: turn on third party access
If your account is still on Comcast, one setting blocks most people. Apple Mail counts as a third party program, and Comcast turns that access off by default.
Turn it on first, or the Mail app will never connect.
- On a computer or phone browser, sign in to your email at xfinity.com/email.
- Click the Settings gear in the top right corner.
- Click Email Settings, then Security.
- Check the box under Third Party Access Security and save.
This step does not apply to accounts already on Yahoo, since Yahoo handles access its own way.
Add Comcast email to the iPhone Mail app
These steps are for an account still on Comcast’s system. You will add it by hand and enter Comcast’s mail servers.
- Open the Settings app.
- Tap Apps, then tap Mail.
- Tap Mail Accounts, then tap Add Account.
- Tap Other, then tap Add Mail Account.
- Type your name, your full comcast.net email address, your password, and a short description like “Comcast.” Tap Next.
- Make sure IMAP is selected at the top.
- Under Incoming Mail Server, enter the host name, your email, and password. Do the same under Outgoing Mail Server.
- Tap Next, then Save.
Use these server settings when the phone asks.
| Setting | Incoming (IMAP) | Outgoing (SMTP) |
|---|---|---|
| Server name | imap.comcast.net | smtp.comcast.net |
| Port | 993 | 587 |
| Security | SSL on | SSL or TLS on |
| Username | Your comcast.net address | Your comcast.net address |
| Password | Your Xfinity password | Your Xfinity password |
Your email password is the same one you use to sign in to any Xfinity page. Once the account saves, open the Mail app and your Comcast folders appear.
If your account already moved to Yahoo
After the move, your comcast.net mailbox is a Yahoo mailbox. You keep the same address, but Yahoo now runs it, so you add it as a Yahoo account.
- Open the Settings app.
- Tap Apps, then tap Mail.
- Tap Mail Accounts, then tap Add Account.
- Tap Yahoo in the list.
- Enter your full comcast.net address and your password, then follow the prompts to allow access.
Apple Mail fills in the Yahoo servers for you, so you do not type any of them by hand. The Yahoo Mail app is another option if you prefer it.
Read Comcast email in a browser instead
You do not have to use an app at all. Any browser on your iPhone can open your inbox.
Go to xfinity.com/email and sign in with your Xfinity username and password. If your account has moved, that page prompts you to sign in through Yahoo.
This is the fastest way to check mail on a phone that is not yours, since nothing is saved on the device.
What happened to the Xfinity Connect app?
Comcast retired the Xfinity Connect email app back in 2021. There is no direct replacement app from Comcast for email.
So the current choices are the Apple Mail app, a web browser, or the Yahoo Mail app once your account moves. If an old guide tells you to download Xfinity Connect, it is out of date.
If setup fails
Most failures on a Comcast account come down to that third party access box being off. Turn it on at xfinity.com/email, then try adding the account again.
If the password is rejected, reset it on the Xfinity site and use the new one. The email password and the account password are the same.
If your Xfinity account uses two step verification, the plain password may not work in Apple Mail. In that case, create an app specific password in your Xfinity security settings and enter that instead.
Still nothing in the inbox? Sign in through a browser first to confirm there is actually mail waiting. If there is, close the Mail app fully and reopen it, or restart the phone.
Once mail is flowing, you can decide how it alerts you. The guide on automatic email updates on your iPhone shows how to control those notifications.
If real messages land in the wrong place, the steps to stop emails going to junk on iPhone can help. And if you plan to send photos, check the email size limits for sending photos first.
Frequently asked questions
What are the Comcast email settings for iPhone?
For an account still on Comcast, incoming mail is imap.comcast.net on port 993 with SSL on. Outgoing mail is smtp.comcast.net on port 587 with SSL or TLS on. Your username and password are your normal Xfinity sign in details.
Why will my Comcast email not connect on my iPhone?
The usual reason is that Third Party Access Security is turned off in your Xfinity email settings. Sign in at xfinity.com/email, open Security, and check that box. Then add the account again in Apple Mail.
Is there a Comcast email app for iPhone?
No. Comcast shut down its Xfinity Connect email app in 2021 and did not replace it. Use the Apple Mail app or a browser, or the Yahoo Mail app if your account has moved to Yahoo.
Will my comcast.net address change when it moves to Yahoo?
No. You keep the same comcast.net address. Yahoo simply takes over running the mailbox, so you sign in through Yahoo instead of Xfinity after the move.
