# Postage vs Superhuman for Email with AI Agents

https://postageformac.com/guides/postage-vs-superhuman (checked 2026-10-29)

Both let Claude and other agents work in your email. Superhuman's Mail MCP is a hosted service for Gmail and Outlook accounts on its Business and Enterprise plans ($33 per member a month billed yearly, $40 monthly). Postage is a native Mac mail app whose MCP server runs on your own Mac, works with any IMAP account, and costs $39 once.

## Where Superhuman is the better fit

If your team already lives in Superhuman on Gmail or Outlook and wants the assistant in Claude or ChatGPT on the web, its Mail MCP connects without anything running on your Mac.

## Where Postage is the better fit

- **Your mail isn't only Gmail or Outlook.** iCloud, Fastmail, Yahoo and any IMAP server work.
- **You want the server on your Mac.** Postage's MCP server is not reachable from the internet, and Postage talks to your mail provider directly.
- **You work in Claude Code, Codex or Cursor.** One-click setup for each, with a token per agent and three access levels.
- **You'd rather pay once.** $39, no per-member subscription.

## Questions

### Does Postage need a Superhuman or Google Workspace plan?

No. Postage works with the mail accounts you already have and the agent apps you already use. There's nothing else to subscribe to.

### Can agents send mail in Postage?

No. Their messages open in a Postage compose window and only you can press Send.

Postage is $39 once, for macOS 14 Sonoma or later: https://postageformac.com/pricing
