Xfinity / Comcast Email Settings: POP3, IMAP, and SMTP

When you sign up with Comcast, you get a Comcast email address and a web gateway through which to access that account. This guide will show you the Comcast and Xfinity email settings you need to work on if you wish to use another client to access your mailbox.

Comcast SMTP Settings

If you have an account with Comcast and you want to configure your mail client to send emails, all you need to do is enter the following Comcast SMTP settings into the server configuration area of your mail client:

Option Description
SMTP Host:
SMTP Port: 465 or 587 TLS (use SSL if TLS isn't shown)
SMTP Username: Your full mailbox address (
SMTP Password: Your email account password

Xfinity / Comcast Email Server Settings For Receiving Emails

The protocols POP3 and IMAP are both used to receive emails. The general Xfinity / Comcast POP and IMAP settings listed below will allow you to get the most out of the incoming email services.

Additional Key Points to Remember

Aside from the various email settings, it is also essential to take note of the following points to use Comcast to its full potential.

💡 Note: Customers who use a third-party email application through a POP connection are now obliged to use a secure mail server and are no longer allowed to utilize POP Port 110. The company made this change to improve the security of customers' email and Xfinity credentials and prevent them from being compromised.

Customers must ensure that their email client gets configured to use the secure Port 995, even if the system will still support POP.

The following are the general guidelines for transitioning to IMAP.

When using certain email clients, moving from POP to IMAP is as easy as inputting your Comcast email address and password. This ease of use extends to many client applications. However, if this common solution does not work, you might want to try the following steps:

  1. On the device, you can access your Comcast mail account, look for your email application's Settings or Preferences section.
  2. Select Add new (IMAP) account from the menu.
  3. When prompted, enter your Comcast mail address and password and hit submit.
  4. Now, you should separate POP and IMAP accounts from Comcast.

💡 Note: Before you delete your POP account, ensure that any emails or folders you want to save move into your new IMAP account. If you delete your POP account without doing this, you will lose them.

POP3 vs. IMAP Email Servers: How To Choose

There are two types of MAA protocols: IMAP and POP3. IMAP and POP3 are both used to retrieve messages from the mail server and send them to the recipient's device.

IMAP syncs all devices and apps linked to an email account with the server and keeps a master copy. Thus, the system will reflect any changes you make on one device across all of them if they get connected to the same mail account.

On the other side of the coin, POP3 does not provide this kind of synchronization. You can download all emails on the server to your device and choose whether or not to keep the server copy. There is no way for changes made on the device to get communicated back to the server.

In the end, IMAP is preferable to POP3 when it comes to synchronizing your email because it is the method that will save you the most time and effort.
