Connect Yandex Mail to Grok

Updated 29 October 2026

Yes — Grok can read, search and reply to your Yandex Mail through Mailopoly. Connect Yandex Mail to Mailopoly over IMAP with a Yandex app password, add Mailopoly to Grok as a custom connector, sign in and ask. One connection covers Yandex Mail and every other account you own. IMAP is off by default and has to be enabled in Yandex Mail settings; with two-factor authentication on (which Yandex recommends) you need an app password, not your normal password.

This guide also covers yandex.ru and yandex.com — the steps are the same.

Before you start

A Mailopoly account — 7-day free trial, no credit card.
IMAP is off by default and has to be enabled in Yandex Mail settings; with two-factor authentication on (which Yandex recommends) you need an app password, not your normal password.
Grok at grok.com or in the Grok apps. On Grok Business or Enterprise, an admin adds the connector for the team first.

Connect Yandex Mail to Grok in three steps

1 Connect Yandex Mail to Mailopoly

Start a Mailopoly account at mailopoly.com/sign-up — 7-day free trial, no credit card.
In Yandex Mail, open Settings → Email clients and enable IMAP. Yandex's mail client help has the current steps.
In Yandex ID → Security → App passwords, create a password of type Email and copy it.
In Mailopoly choose Add email account, enter your Yandex address and paste the app password. Mailopoly fills in the server settings for you.

2 Add Mailopoly to Grok

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

Add Mailopoly to Grok

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

Go to grok.com/connectors.
Choose New Connector, then Custom, and enter https://fastapi.prod.aws.mailopoly.com/mcp-server/ as the MCP server URL. If it asks for a name, use Mailopoly.
Sign in with your Mailopoly account when prompted, then choose what Grok is allowed to do. Reading, making changes and sending are separate permissions.
Back in a chat, ask.

Grok takes Mailopoly as a custom connector, so the only thing to paste is one address. On Grok Business and Enterprise, an admin adds the connector for the team first in the xAI console. This is Grok's chat at grok.com and in the Grok apps; a Grok Bot has its own guide.

3 Ask about your Yandex Mail

Whatever you've connected to Mailopoly is what your assistant can reach. Some things people ask on day one:

Summarise my Yandex Cleanbox for today.
Find the delivery notification in my Yandex mail and track the parcel.
Reply to the last email from the agency from my Yandex address.

Yandex Mail 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.yandex.com
Port	993
Security	SSL/TLS
Username	Your full email address
Password	Yandex app password (type: Email)

What Grok can do with Yandex Mail through Mailopoly

Search Yandex Mail — 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 Yandex Mail 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 Yandex Mail 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 Yandex Mail 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 Grok at any time from Settings → Security in the Mailopoly app. More on the security page.

What goes wrong with Yandex Mail, and the fix

IMAP is off by default. Enable it under Settings → Email clients first, or every mail app is refused.
With two-factor on, your normal password is rejected. Create an app password of type Email in Yandex ID.
Business (Yandex 360 for Business) accounts may also need IMAP allowed by the organisation admin.
No Custom option under New Connector: on Grok Business and Enterprise, connectors are managed by an admin in the xAI console — ask them to add Mailopoly for the team.
