# Resend Inboxes alternative for AI agents

Resend Inboxes is in private beta: you request early access, install preview
builds of the SDK and CLI, and Resend notes that the response shape might
change before general availability. If you need an inbox for an AI agent
now, Botmail is generally available today. Your agent claims an address
like `ada@botmail.pro` in one step, you approve it with one click, and it can
read, search, reply, draft and wait for mail right away, with no domain to
verify.

```sh
npx botmail claim ada --human you@example.com
```

Botmail isn't affiliated with Resend. This page compares the two from public
documentation so you can pick the right one.

## When Botmail is the better fit

- **You want to start today.** No waitlist, no preview SDK. The REST API, the
  [MCP server](https://botmail.pro/guides/email-mcp-server) and the [CLI](https://botmail.pro/cli) are stable.
- **Your agent needs its own address, not your domain's.** Resend Inboxes live
  at an address on a domain you verify (`support@example.com`). Botmail
  addresses exist the moment your agent claims one: no DNS, no MX records.
- **The agent should set itself up.** On Resend, a person creates the account,
  the API key and the inbox. On Botmail the agent claims its own address and
  you approve it from a single email.
- **You want a human check before sends.** Botmail drafts come with a review
  link you open to read the email and press Send, without signing in to a
  dashboard. Mail to new recipients is checked for spam and phishing before
  delivery.
- **Your agent needs verification codes.** `botmail wait --from github.com
  --extract code` blocks until the email arrives and prints the code. Over
  MCP, `wait_for_mail` does the same job.

## When to wait for Resend Inboxes

- Your team needs a **shared support inbox** with assignment, and you want
  Resend's hosted agent to triage and draft replies in it.
- Mail must come from **your own domain** today. Botmail doesn't support
  custom domains yet.
- You already send with Resend and want everything in one account.

## Questions

### Is Resend Inboxes available?

As of October 2026, Resend Inboxes is in private beta. You request early access, use preview SDK and CLI builds, and Resend says the response shape might change before general availability.

### What is a good Resend Inboxes alternative for AI agents?

Botmail is generally available and built for agents: the agent claims an address like ada@botmail.pro itself, you approve it with one click, and it gets threads, drafts, labels, search and long-polling over REST, MCP or a CLI.

### Do I need my own domain?

Resend Inboxes uses an address on a domain you verify. Botmail gives the agent a botmail.pro address with no DNS setup; custom domains aren't supported yet.

### Is Botmail affiliated with Resend?

No. Botmail is an independent service operated by Exon Enterprise LLC. The comparison uses Resend's public documentation.
