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 Private Email
Whatever you've connected to Mailopoly is what your assistant can reach. Some things people ask on day one:
- What's in my business inbox that needs a reply today?
- Find the client's signed contract in my mail and save it to PolyBox.
- Reply to the last enquiry from my business address.

What Claude and ChatGPT can do with Namecheap Private Email through Mailopoly
- Search Namecheap Private 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 Private 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 Private 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 Private 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 Namecheap Private Email, and the fix
- The server is mail.privateemail.com, not mail.yourdomain.com, even though your address is on your own domain.
- Use your full email address as the username, not just the part before the @.
- Your Namecheap account password is not the mailbox password. Mailbox passwords are set per mailbox in the Private Email dashboard.
