Connect Comcast Email to Claude and ChatGPT
Yes — Claude and ChatGPT can both read, search and reply to your Comcast Email through Mailopoly, which is listed in the Claude Connectors Directory and is an approved app in the ChatGPT app directory. Connect Comcast Email to Mailopoly with a Yahoo-generated app password, add Mailopoly in Claude or ChatGPT, and ask. The whole setup takes about a minute. Comcast has moved @comcast.net email to Yahoo Mail, so you sign in with your full @comcast.net address and a Yahoo app password; your Xfinity password won't work.
This guide also covers Xfinity email and comcast.net — the steps are the same.
Before you start
- A Mailopoly account — 7-day free trial, no credit card.
- Comcast has moved @comcast.net email to Yahoo Mail, so you sign in with your full @comcast.net address and a Yahoo app password; your Xfinity password won't work.
- Claude on any plan, including Free, or ChatGPT with apps enabled.
Connect Comcast Email to Claude or ChatGPT in three steps
1Connect Comcast Email to Mailopoly
- Start a Mailopoly account at mailopoly.com/sign-up — 7-day free trial, no credit card.
- Sign in to your Comcast mailbox on Yahoo, open Account Security and choose Generate app password. Name it Mailopoly. Yahoo's help article on Comcast mail covers the move.
- Copy the app password. Yahoo shows it once.
- In Mailopoly choose Add email account, enter your full @comcast.net address, and paste the app password in the password field. Mailopoly uses Yahoo's mail server for you.

2Add Mailopoly to Claude or ChatGPT
This part is the same whatever you connected in step 1. Mailopoly is listed in both directories, so it's a search and a tap — no endpoint URL to paste.
Claude
- Open Settings → Connectors on claude.ai or in the Claude app — or choose Add connectors from the + menu in any chat.
- Search the directory for Mailopoly and choose Connect.
- Sign in with your Mailopoly account when prompted, then choose what Claude is allowed to do. Reading, making changes and sending are separate permissions.
- Back in the chat, make sure the Mailopoly connector is switched on, then ask.
One listing covers Claude.ai, Claude Desktop, Claude mobile, Claude Code and Cowork, and it works on every Claude plan, including Free. In Claude Code you can also run claude mcp add --transport http mailopoly https://fastapi.prod.aws.mailopoly.com/mcp-server/ and then /mcp to sign in.
ChatGPT
- Open the Apps directory in ChatGPT — from the + menu in any chat, or Settings → Apps & Connectors.
- Search for Mailopoly and choose Connect.
- Sign in with your Mailopoly account when prompted, then choose what ChatGPT is allowed to do. Reading, making changes and sending are separate permissions.
- In any chat, type
@Mailopolyand ask.
Mailopoly is an approved app in the ChatGPT app directory, so there's no developer mode and no endpoint URL to paste. Once connected it's available in every ChatGPT conversation on the web and in the mobile apps.
Using something else? Claude Code, Cowork, Codex and any client that supports remote MCP servers connect the same way — the Mailopoly MCP page has the endpoint and per-client steps.
3Ask about your Comcast email
Whatever you've connected to Mailopoly is what your assistant can reach. Some things people ask on day one:
- What did Xfinity bill me this month? Check my Comcast email.
- Summarise the last week of my Comcast Cleanbox.
- Reply to the neighbourhood association email from my Comcast address.
Comcast Email server settings
Mailopoly fills these in for you when you enter your address. They're here in case you need to check them or your provider uses something unusual.
| IMAP server | imap.mail.yahoo.com |
|---|---|
| Port | 993 |
| Security | SSL/TLS |
| Username | Your full email address |
| Password | Yahoo app password (not your Xfinity password) |
What Claude and ChatGPT can do with Comcast Email through Mailopoly
- Search Comcast Email — and every other account you own — in one question. By sender, date, topic, or the half-remembered phrase somewhere in the body.
- Read your Cleanbox, not your whole inbox. Mailopoly sorts Comcast email as it arrives: personal and important mail in Cleanbox, promotions and newsletters in Other. Ask for either.
- Summarise a thread, a day or a week. "What did the school send this week?" comes back as an answer, not a list of links.
- Reply from your Comcast email address, in your voice. Save a draft to Mailopoly for review, or send — sending is a separate permission and a confirm-first action.
- Schedule a send for later, and cancel it if you change your mind.
- Pull out invoices, events and deliveries. Amounts and due dates, calendar invitations, parcel tracking — extracted on arrival and added to My Day.
- Find an attachment. Every attachment from Comcast email lands in PolyBox, so "find the PDF the accountant sent" just works.
- Unsubscribe, snooze, file and mark read from the chat, on whichever account the mail belongs to.
Reading, making changes and sending are separate permissions you grant when you connect, and you can revoke an assistant at any time from Settings → Security in the Mailopoly app. More on the security page.
What goes wrong with Comcast Email, and the fix
- Your Xfinity password won't work. Since the move to Yahoo, mail apps need a Yahoo app password generated from the account security page.
- The mail server is Yahoo's, imap.mail.yahoo.com — not a comcast.net address. Mailopoly fills this in.
- If your mailbox hasn't been moved yet, the Yahoo steps won't apply. Contact Mailopoly support and we'll connect it to Comcast's own servers.
