To connect Yahoo Mail to Claude or ChatGPT, create a Yahoo app password, add your Yahoo mailbox to Fezola, then add Fezola to your assistant. Yahoo does not accept your usual password for other apps, so the app password is the one step people miss. Yahoo's servers come pre-filled in Fezola: you only enter your address and the app password.
Yahoo's settings
Read from Yahoo's IMAP help page, checked on 15 November 2026. Yahoo can change them, so check the page before relying on them.
| Server | Port | Encryption | |
|---|---|---|---|
| Incoming mail (IMAP) | imap.mail.yahoo.com | 993 | SSL |
| Outgoing mail (SMTP) | smtp.mail.yahoo.com | 465 or 587 | SSL |
Table as of 15 November 2026.
- Username: your complete Yahoo address, including the domain.
- Password: an app password, not your account password.
- SMTP authentication: required.
Fezola uses 993 for reading and 465 for sending. In the app, choose Yahoo and nothing else needs typing.
Which assistant, which plan
| Assistant | Custom connector | Source |
|---|---|---|
| Claude | Free (one custom connector), Pro, Max, Ultra, Team, Enterprise | Anthropic help page, checked 15 November 2026 |
| ChatGPT | Business and Enterprise/Edu; Pro with read and fetch permissions | OpenAI help page, as cited in our ChatGPT guide |
Table as of 15 November 2026. Neither assistant ships a Yahoo Mail connector of its own, so a custom connector is the way in. A single connector that covers several services, like Fezola, fits the one custom connector of Claude's Free plan.
Setup in six steps
- Create a Yahoo app password. Sign in to your Yahoo account, open Account security, then generate an app password (the Yahoo account security page is where it lives). Name it Fezola and copy the generated code.
- Create a Fezola account. It is free with 2 sources.
- Add the mailbox. In Sources, add a mailbox, choose Yahoo, enter your address and paste the app password.
- Test the connection. Fezola tests receiving and sending separately.
- Add Fezola to your assistant with
https://api.fezola.com/mcp: see how to add a custom connector to Claude or how to add an MCP server to ChatGPT. - Ask a question: "What came into my Yahoo inbox this week that needs an answer?"
The short version is in the Yahoo Mail guide.
What you can ask
- "Which unread emails did I get this week in my Yahoo mailbox?"
- "Find the invoice from my internet provider, in all my mailboxes."
- "Draft a reply to the last email from my bank."
Attachments in PDF, Word, text and image formats can be read by the assistant: see read email attachments with AI.
Guardrails
- Drafts by default. Replies are saved in your Yahoo Drafts folder and you send them yourself. Direct sending is off until you switch it on, mailbox by mailbox.
- Revocable access. The app password only opens your mail. Delete it in Yahoo's security settings and Fezola loses access, with your main password untouched.
- Which mailbox is which. Search results carry the mailbox name; the address shows when a message is opened.
For the security side, read is it safe to give AI access to your email.
Common errors
- Authentication failed: you used your normal password. Generate an app password and paste it instead.
- Connection refused: check that the username is the complete address, with the domain.
For other providers, see AOL, Comcast, OVH and the IMAP connector page. Several mailboxes? See search all your inboxes with Claude.
