Connect Zoho Mail to Grok

Updated 29 October 2026

Yes — Grok can read, search and reply to your Zoho Mail through Mailopoly. Connect Zoho Mail to Mailopoly over IMAP, with an application-specific password if you use two-factor authentication, add Mailopoly to Grok as a custom connector, sign in and ask. One connection covers Zoho Mail and every other account you own. IMAP has to be enabled in Zoho Mail settings first, and if two-factor authentication or SAML is on, you need an application-specific password instead of your normal password.

This guide also covers zohomail.com and organisation domains hosted on Zoho Mail — the steps are the same.

Before you start

A Mailopoly account — 7-day free trial, no credit card.
IMAP has to be enabled in Zoho Mail settings first, and if two-factor authentication or SAML is on, you need an application-specific password instead of 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 Zoho Mail to Grok in three steps

1 Connect Zoho Mail to Mailopoly

Start a Mailopoly account at mailopoly.com/sign-up — 7-day free trial, no credit card.
In Zoho Mail, open Settings → Mail Accounts and turn on IMAP Access. Zoho's IMAP access help has the current steps.
If two-factor authentication (or SAML sign-in) is enabled on your account, generate an application-specific password in Zoho Accounts and use that. Otherwise your normal Zoho password works.
In Mailopoly choose Add email account, enter your Zoho address and the password. Mailopoly fills in the server settings; for an organisation domain on Zoho it uses the imappro server.

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 Zoho Mail

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

What came into my Zoho work inbox from clients today?
Find the signed contract in my Zoho mail and save it to PolyBox.
Draft a reply to the supplier's quote from my Zoho address.

Zoho 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.zoho.com Organisation domains: imappro.zoho.com EU data centre organisations: imappro.zoho.eu
Port	993
Security	SSL/TLS
Username	Your full email address
Password	Normal Zoho password, or an application-specific password if two-factor or SAML is on

What Grok can do with Zoho Mail through Mailopoly

Search Zoho 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 Zoho 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 Zoho 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 Zoho 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 Zoho Mail, and the fix

IMAP is off by default. Until you enable it under Settings → Mail Accounts, every mail app is refused, whatever password you use.
Two-factor changes the password you need. With two-factor or SAML on, your normal password is rejected — generate an application-specific password.
Organisation accounts use a different server (imappro.zoho.com, or imappro.zoho.eu for EU-hosted organisations). Mailopoly picks the right one from your domain; check it if a connection fails.
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.
Setting up a Grok Bot instead? This guide is for Grok's chat at grok.com and in the Grok apps. A Grok Bot has its own guide: Connect Grok Bot to your email.
