Connect Comcast Email to Perplexity

Updated 1 November 2026

Yes — Perplexity can read, search and reply to your Comcast Email through Mailopoly. Connect Comcast Email to Mailopoly with a Yahoo-generated app password, add Mailopoly to Perplexity as a custom connector, sign in and ask. One connection covers Comcast email and every other account you own. 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.
Perplexity Pro, Max or Enterprise — custom connectors aren't on the free plan. On Enterprise, an admin allows custom connectors first.

Connect Comcast Email to Perplexity in three steps

1 Connect 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.

2 Add Mailopoly to Perplexity

This part is the same whatever you connected in step 1.

Add Mailopoly to Perplexity

These steps are taken from public documentation, and we haven't yet checked each one in Perplexity ourselves. If a label doesn't match what you see, Perplexity's own help page, linked below, has the current wording.

In Perplexity, open Account settings → Connectors.
Choose + Custom connector at the top right, then Remote.
Name it Mailopoly and enter https://fastapi.prod.aws.mailopoly.com/mcp-server/ as the MCP Server URL. For Authentication choose OAuth 2.0 — there's no client ID or secret to fill in, Mailopoly registers Perplexity itself — and for Transport choose Streamable HTTP.
Tick the box confirming you understand the risks of custom connectors, choose Add, then click the Mailopoly card to sign in.
Sign in with your Mailopoly account, then choose what Perplexity is allowed to do. Reading, making changes and sending are separate permissions.
Back in Perplexity, ask.

Perplexity takes Mailopoly as a custom remote connector, so the only thing to paste is one address. Custom connectors are available on Perplexity Pro, Max and Enterprise; on Enterprise, an admin has to allow them for the organisation first.

3 Ask 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 Perplexity 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 Perplexity 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.
No + Custom connector button in Perplexity: custom connectors need Perplexity Pro, Max or Enterprise. On Enterprise, ask your admin to allow custom connectors for the organisation.
The Mailopoly card says it isn't connected: adding the connector doesn't sign you in. Click the Mailopoly card in Account settings → Connectors and finish the Mailopoly sign-in.
Perplexity can't reach the server: check the address is exactly https://fastapi.prod.aws.mailopoly.com/mcp-server/, Authentication is OAuth 2.0 and Transport is Streamable HTTP, then remove the connector and add it again.
