# MCPmailer vs Zoho Mail

Zoho Mail is the cheapest real mailbox per user. MCPmailer gives agents addresses with no seat, no IMAP tier, and quotas built for software.

## What Zoho Mail is

Zoho Mail is the value pick in hosted email: roughly a dollar per user a month on Mail Lite, four on Premium, with a genuine free tier for a handful of users on one domain. It is the email component of a much larger and cheaper office suite, and for humans it is a lot of product for the money.

## Where Zoho Mail is the better choice

If you want a normal mailbox a person logs into, on your domain, for the least money, Zoho is hard to beat and we are not competing for that job. It is also the sensible choice if your agent must live inside a mailbox a colleague also reads.

## Where MCPmailer differs

The price stops being the deciding factor once the mailbox has to be driven by software. Every agent is another user, IMAP and POP are absent from the free tier so a prototype starts paid, and nothing in a hosted mailbox distinguishes a reply from cold outreach or gives you a tool surface an agent can use directly.

### A dollar a month is still a seat

Per-user pricing is fine for ten people and wrong for a fleet of narrow agents, because an agent that sends forty emails a month costs the same as a full-time employee. We charge a base plan plus metered mail, so the cost tracks what the agents actually do.

### No IMAP on the free tier

Zoho's free plan omits IMAP and POP, so the cheapest way to try an agent against a real mailbox is a paid plan and an app password. Our free tier is 3,000 emails a month with the full MCP surface, because an agent that cannot be driven is not worth evaluating.

### Mailbox protocols are not agent tools

IMAP hands a model raw folders and MIME. Ours hands it get_thread, search_inbox, wait_for_reply, and structured refusals. The gap is not convenience: it decides whether the agent can reason about a conversation or has to reassemble one first.

## Where each belongs

Almost nobody should move their people off hosted email. Move the automation.

1. **People stay on Zoho** Mailboxes, calendar, and the rest of the suite are untouched.
2. **Agents get a subdomain** agents.yourcompany.com, separate from the domain your staff send from, so agent behaviour cannot affect their delivery.
3. **Retire the app passwords** A key scoped to one mailbox replaces an IMAP credential that could read everything in the account.

## Side by side (checked July 2026)

| | MCPmailer | Zoho Mail |
| --- | --- | --- |
| Built for | Software, not people. No seats, no consent screen, no inbox a human also lives in. | People, cheaply, as part of an office suite. |
| Inbox per agent | One mailbox per agent with no licence attached, created in seconds, deleted as easily. | One user per agent, billed per user. |
| Receiving and threading | Inbound MX, parsed MIME, In-Reply-To threading. The whole conversation stays queryable. | Yes, it is a mailbox. IMAP or POP on paid plans. |
| MCP server | Native. Streamable HTTP with a bearer key, or OAuth 2.1 for clients that cannot hold one. | No. |
| Waiting for a reply | wait_for_reply long-polls the mailbox until the other side answers, up to five minutes per call. | Polling over IMAP. |
| Human oversight | A colleague can watch what the agent wrote without being given the mailbox. | Admin console for the domain. |
| Sending limits | Built for automation, so sending programmatically is the supported path rather than the terms violation. | Hosted-mailbox sending limits, written for people. |
| Your domain | A subdomain for agents, kept away from the domain your people send from. | Your domain, one domain on the free plan. |
| Search | Full-text search across the workspace, exposed to the agent as search_inbox. | Good, within one mailbox. |
| Beyond the inbox | A shared contact book with per-contact memory, notes, an encrypted vault, and a public hostname per agent. | The Zoho suite: CRM, docs, projects. |
| Free tier | 3,000 emails a month, 100 a day, 3 inboxes, no card. | Free for a few users on one domain, without IMAP or POP. |
| Content privacy | We never read message content and never train on it. Enforcement is behavioral and metadata only. | Zoho's terms, per account rather than per agent. |

## Questions

### Can I run an AI agent on Zoho Mail?

Yes, with a paid plan and an app password over IMAP and SMTP. You are then writing MIME parsing, thread matching, and your own oversight, and paying per agent.

### Is Zoho cheaper than MCPmailer?

For a few agents that barely send, yes. Once you count parsing, threading, and per-agent revocation as work you would otherwise do yourself, the comparison changes.

### Does the free Zoho plan work for a prototype?

Not for an automated one. IMAP and POP are not included, so there is no clean programmatic path in.

### Can agents send from our Zoho domain?

Better not to. Put agents on their own subdomain so a cold-send mistake cannot damage the reputation your staff depend on.
