Connect a Zoho mailbox so your agents can send from it. The wizard asks for an app password (a separate code you create in your Zoho security settings) rather than the password you sign in with.

​
Before you begin

  • You can sign in to this mailbox yourself. Create the app password while signed in to the exact mailbox you are connecting, not to another account you also own.
  • Somewhere to paste the code the moment it appears. Most providers show an app password once and never again.
  • If two-factor authentication is on for that Zoho account, the ordinary account password will not pass verification here. The app password is the only credential that works.

​
Connect the mailbox

1

Open the provider list

Go to and choose Add senders. On the panel, choose Connect your email, whose button reads Connect.Gmail and Outlook lead as their own cards. Everything else sits in the All providers grid below them, in alphabetical order, which puts Zoho last. Choose it.
2

Create an app password in Zoho

The wizard opens on Get ready: create an app password, which explains what one is: a separate code, generated in your Zoho security settings, that lets us send without ever knowing your real password. Create it there and copy it straight away.Back on the wizard, choose I have my app password.
3

Enter your account details

On the Your account screen, put the mailbox address in Email address and the name recipients should see in Sender name. The name on your own account is used there by default, so change it only if you want something else. Choose Continue.
4

Paste the app password and verify

Paste the code into App password. The helper under the field says the same thing: the app password you just created, not your regular Zoho password.Under the field, the wizard prints the sending server it is about to use: host, port and security type, next to an Edit link. Edit adds a Server settings step where you can change the sending and receiving servers by hand. Left alone, Zoho’s own values are used: smtp.zoho.com for sending and imap.zoho.com for reading replies, both over SSL.Choose Verify connection. We open a real connection to Zoho for both sending and receiving, because a mailbox that can send but not receive would never see a reply.

​
What happens next

A confirmation panel reads “Your email is connected” with the mailbox address under it. Choose Done, and the mailbox is on the Email Accounts page.
An account connected through this wizard arrives with no sending schedule, and its row shows No Schedule rather than Active. That chip is not a warning you can ignore: a send only goes out when the current day and time fall inside one of the account’s sending hours, so until you set them, nothing sends. The chip is a link: it opens that account’s schedule section. Sender settings covers the fields there. Once the schedule exists, the row shows No Campaigns until a campaign is attached to the account, and Active after that. A brand-new mailbox does not send at full volume even then. See Smart Daily Limit for how the daily number is worked out, and The quarantine and ramp-up for new mailboxes for what to expect in the first month. The server values the Zoho tile filled in are not hidden from you afterwards. Open the account from Email Accounts and its first section holds the same fields, with the SMTP and IMAP boxes behind an Advanced settings toggle.

​
Troubleshooting

Zoho rejected this address and password together, so check both. Choose Re-enter password to go back to the field. Nothing you typed is lost.A partly copied app password fails exactly like a wrong one, and so does one created while signed in to a different account. If you are unsure which you pasted, generate a fresh app password in Zoho and use that.
Sending only works when we can also read replies, and IMAP access looks turned off for this mailbox. The screen walks you through it: open your Zoho mailbox settings, find the IMAP section (sometimes labelled “external access”) and turn it on, then come back and choose Try again.
A connected mailbox is not the same as a sending one. Check the schedule first, since an account connected this way starts without one. After that the usual causes are an agent whose outreach is still paused and a new mailbox whose daily limit is still zero. Work through No sending channel connected, which goes over them in the order worth checking.
