Connect it in two minutes
Add the Nilyo app in ChatGPT, or enable developer mode and add a connector with the URL https://nilyo.com/mcp and OAuth. Then connect the mailbox: give the address and the password and the servers are detected from the address — you normally never type a host or a port. Only if detection fails are you asked for them, and the authoritative place to copy them from is the account settings of the mail client you already use.
The account password will not work
Yahoo disabled plain password access for external mail clients some years ago, so the only credential that authenticates is an app password created in the account security settings. If you already use Yahoo in a desktop mail client, you have generated one before and can create another rather than reusing it — a separate credential per connection is what lets you revoke one without breaking the other.
What it is actually good for here
A consumer inbox is heavy on newsletters and light on threads that need you, which is exactly the shape where triage pays: telling you which four of two hundred messages expect an answer. Moving or deleting mail is an explicit action, so nothing is tidied away behind your back.
“What arrived since yesterday that needs an answer from me?”
“Find the thread where we agreed the delivery date and quote the message.”
Reading a consumer inbox is mostly triage
A Yahoo inbox is typically heavy on newsletters and light on threads that need you. That is the shape where an assistant earns its place: not reading the mail, but telling you which four of two hundred messages actually expect an answer.
When it stops working
Two causes cover nearly everything. The password is refused after it worked: an application password was revoked, or the mailbox password was changed — generate or update it and reconnect the same mailbox rather than adding a second one. The agent suddenly sees nothing: the session expired, and the card in the answer carries the reconnection link. A mailbox that moved host is reconnected with the new servers, not re-added, so anything referring to it keeps working.
Common questions
Can ChatGPT read Yahoo Mail?
Yes, over IMAP, using an app password from Yahoo’s account security settings. The account password is not accepted by external clients.
Do I need to configure servers?
No, they are detected from the address; you are only asked if detection fails.
Can it sort my inbox?
It can read and triage — tell you what needs an answer, group by sender, summarize. Moving or deleting mail is an explicit action you ask for.
How Email works with Nilyo
Connection. Gmail and Microsoft 365/Outlook through their official sign-in (the “Unipile” name appears on the consent screen: Unipile SAS operates the connection). Any other mailbox through IMAP/SMTP: OVH, Zoho, iCloud, IONOS, Infomaniak, Fastmail, Yahoo, GMX and self-hosted servers.
What your agent can do. Folders and labels, listing and searching messages, reading with attachments, drafts, sending and true replies, moving and labelling, contacts on Gmail and Microsoft.
Pacing and safety. No local budget; provider limits apply. IMAP mailboxes are read live, so listings are paged (50 messages max per page).
- “How many emails today” uses the folder counts of the mailbox; “today” is a date filter, never a guess.
- On IMAP a message id changes after a move; Nilyo returns the new id so the agent keeps working on the right message.
