ANSWERED: How to Set Up Your Comcast Email Address with an Email Program

Ready to get started using your email? No problem. Our Xfinity Email website comes set up and ready for you to use. But if you prefer using an email program instead, these settings will have you up and running in no time!

Please note:

  • Using third-party email programs to access your email can potentially expose your Xfinity ID and password to fraud and other risks.
    • We recommend you access your email by going to the Xfinity web portal and clicking Email.
  • Xfinity Email service requires an Xfinity ID and password when sending messages.
    • If you’re getting an error while sending an email, follow the instructions below for your specific program type to verify your settings.

Email Setup

  • First, you'll have to allow access to third-party programs in the Xfinity Email website, or you may get an error message when you try to set up your email.
  • Select your program type from the list below for steps to set up your email:
  • For other programs not listed, use these settings to connect your email:
    • Incoming Mail Server Name:
      • Incoming Mail Server Port Number: 993 with SSL ON
    • If the Mail Client lets you select an authentication method, choose STARTTLS.
      • If Needed: 143 with SSL ON
    • Outgoing Mail Server Name:
    • Outgoing Mail Server Port Number: 587 (SMTP)
      • If Needed: 465 (SMTPS)
    • Encryption: TLS (use SSL if TLS isn't shown.)
    • Authentication: Type in your email address

Learn More About Port Numbers and POP vs. IMAP

When you're setting up your email, your program will ask for some information about email "protocols." Here are a couple of things to know:

  • Port Numbers
    • Your email port is how email moves from one email server to another.
    • To protect your security and help prevent spam, we don't support port 25.
    • If you're using an older email program like Outlook Express, Outlook, or Mac Mail, you may have trouble sending email.
    • Learn more about port 25.

  • POP vs. IMAP:
    • POP (Post Office Protocol) and IMAP (Internet Message Access Protocol) are two different ways to get email in your email program.
    • We recommend using IMAP for your email.
      • POP can cause problems when checking your mail from more than one phone or computer because POP removes the mail from our server and delivers it to your device.
      • IMAP makes it easier to sync your email on multiple devices because your folders and mail remain on our server until you move or delete them with your device.
      • With IMAP, the email changes you make on one device, like your smartphone, are reflected on your other devices, like your laptop.
    • But if you'd still like to use POP, use these settings in your email program:
      • Incoming Mail Server Name:
      • Incoming Mail Server Port Number: 995 (POP3 with SSL)
        • Incoming Mail Server Port 110 is no longer supported.
        • Make sure to use port 995 instead.
        • You can check this in your email program's Settings, Advanced Settings or Preferences menu.
