# Connect Yahoo Mail to Claude and ChatGPT

[Connectors](https://lumman.co/mcp) / [Multi Mail](https://lumman.co/mcp/multi-mail)

Multi Mail connects Yahoo mailboxes to Claude and ChatGPT with an app password, never your Yahoo password.

For yahoo.com, ymail.com and rocketmail.com addresses, and other domains whose mail Yahoo Mail's own servers receive.

## The AI apps' own connectors

Multi Mail's other provider pages name what the AI apps' own connectors do for their providers: [Gmail](https://lumman.co/mcp/multi-mail/gmail), [Outlook and Hotmail](https://lumman.co/mcp/multi-mail/outlook), [Microsoft 365](https://lumman.co/mcp/multi-mail/microsoft-365), [iCloud](https://lumman.co/mcp/multi-mail/icloud), [Fastmail](https://lumman.co/mcp/multi-mail/fastmail), [Inkbox](https://lumman.co/mcp/multi-mail/inkbox).

## Connect it

Yahoo makes an app password only in a browser you have signed in to Yahoo with for several days in a row - never in a private window.

1. Sign in to your Yahoo Account Security page at [login.yahoo.com](https://login.yahoo.com/account/security).
2. Under External connections, choose Create app password.
3. Name it Lumman, choose Generate password and copy it. Yahoo shows it once - leave that page open until Lumman asks for it.

4. [Add to Claude](https://claude.ai/directory/connectors/multi-mail) - Opens claude.ai - press Connect there.
5. Sign in, add your Yahoo mailbox and approve Claude in the window Claude opens - choose Another mailbox, type the address and paste the app password when it asks.
6. Ask Claude about your mail

- [Claude](https://lumman.co/mcp/claude) - From Claude's connectors directory
- [ChatGPT](https://lumman.co/mcp/chatgpt) - As a custom MCP server
- [Claude Code](https://lumman.co/mcp/claude-code) - As a plugin, in two commands
- [Cursor](https://lumman.co/mcp/cursor) - In ~/.cursor/mcp.json

## Reach and limits

- Search and read it together with every other mailbox you add.
- Draft, reply, forward and send from it.
- Archive, bin and file its mail, and clean up its inbox by sender, putting back what a clean-up moved.
- Multi Mail reaches no filters or vacation responder at Yahoo.
- Yahoo's default view shows a mail app only each folder's newest messages. Multi Mail reads that view, and says which folder holds more.

## If it refuses

- Yahoo refused this password. Use an app password, not your Yahoo password - made in a browser signed in to Yahoo for several days, never a private window - and check the address.
- Multi Mail does not connect mail Yahoo keeps for another company, such as Rogers or Yahoo's business mail. Nothing was sent.
