Ready to get started using your Comcast email? No problem. Our web-based Xfinity Connect page and app come 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!
If you have questions about your specific program or email client, we've got you covered. Just head to the links section and pick your program. To ensure the security of our network and customers, we no longer support the use of port 25 for sending email. If you use an older email client (Outlook Express, Outlook, Mac Mail, etc.), this might impact your ability to send email. Learn more about port 25.
When your program asks you to set up your email, use these settings to connect your Comcast email:
Incoming Mail Server Name:imap.comcast.net
Incoming Mail Server Port Number:993 with SSL ON
If the Mail Client lets you select an authentication method, chooseSTARTTLS.
If Needed:143 with SSL ON
Outgoing Mail Server Name:smtp.comcast.net
Outgoing Mail Server Port Number:587 (SMTP)
If Needed:465 (SMTPS)
Authentication: Type in yourComcast username and password
Email Setup: Port Numbers and POP vs. IMAP
When you're setting up your email account, your program will ask for some information about email "protocols." Here are a couple of things to know as part of your set-up:
Port Numbers: Your email port is how email moves from one email server to another. To protect your security and help prevent spam, we no longer 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 Comcast 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:pop3.comcast.net
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'sSettings,Advanced SettingsorPreferencesmenu.
