Comcast IMAP settings: connect your Comcast or Xfinity email to Claude and ChatGPT

To read and draft your Comcast or Xfinity mail in Claude or ChatGPT, allow third-party access in your Xfinity Email settings, connect the mailbox to Fezola with Xfinity's IMAP settings, then add Fezola to your assistant. The settings below come from Xfinity's official support page, read on 14 November 2026: Xfinity can change them, so check the page before relying on them.

Xfinity's settings

• Username: your full Comcast.net email address.
• Password: an Xfinity ID and password are required to send, according to Xfinity.
• Prerequisite: allow third-party program access in the Xfinity Email website first. Xfinity links to instructions.
• Not supported: port 25.

Xfinity also lists POP (pop3.comcast.net, port 995). Prefer IMAP.

Setup in four steps

1. Allow third-party access in the Xfinity Email website, following Xfinity's instructions.
2. Add the mailbox in Fezola. Fezola has no Comcast preset: in Sources, add a mailbox, choose Other (custom IMAP) and enter your address, the server imap.comcast.net (port 993), the server smtp.comcast.net (port 587) and your password.
3. Test the connection: Fezola checks receiving and sending.
4. Add Fezola to Claude with https://api.fezola.com/mcp: see how to add a custom connector to Claude. For ChatGPT, see how to add an MCP server to ChatGPT. Then ask: "What needs an answer in my Comcast mailbox?"

A word of caution

Xfinity's page warns that third-party programs can expose your Xfinity ID and password to fraud. Fezola stores credentials encrypted and you can disconnect the source at any time, but connect only what you trust, and revoke the third-party access in Xfinity if you stop.

What you can ask

• "Which unread emails did I get this week in my Comcast mailbox?"
• "Find the bill my provider sent last month, in all my mailboxes."
• "Draft a reply to the last email from my landlord."

What the assistant does not do

Fezola saves replies as drafts in the mailbox that received the message, and you send them yourself. Direct sending is off until you switch it on, mailbox by mailbox.

Common errors

• Connection refused: check that third-party program access is allowed in the Xfinity Email website, and that the username is the full Comcast.net address.
• Wrong port: do not use port 25, which Xfinity does not support.

For other providers, see AOL, GoDaddy, connect a custom domain email and the IMAP connector page. Several mailboxes? See search all your inboxes with Claude.
