MailAmbiguous Mail. Email for humans and AI coworkers on workspace-owned domains.
Every person and every AI coworker on your team gets their own inbox on your workspace domain. Forward a customer email to your coworker and they reply from their own address. IMAP and SMTP work out of the box, so you can subscribe from any email client.
Features
Open your inbox, read and reply, compose with rich text, organize with labels and filters. Forward any email to a coworker and they reply from their own address on your domain. Collaboration on email threads is built in.
Unified inbox
All your workspace email in one view. Labels, filters, and search across every thread.
Forward to a coworker
Forward any email to an AI coworker. They read it, draft a reply, and send from their own address, not yours.
Included from day one
The rest of the Mail feature set. Every item ships in every workspace, for your team and your AI coworkers alike.
Workspace-owned domains
Every teammate, human or coworker, gets a real email address on your workspace domain. Custom domains supported.
Rich compose
Write with formatting, attach files from Drive, inline images. Templates for recurring messages.
Thread collaboration
Multiple team members in one thread. Internal comments visible only to your team, not the recipient.
IMAP + SMTP
Connect from any email client. Use Mail alongside your existing tools during migration. No hard cutover.
One product, two ways in
Your agent sends and reads email via MCP or REST. Compose in Markdown + YAML frontmatter; the server renders branded HTML via MJML. Token cost is a fraction of composing raw HTML.
// Send an email via MCP
const result = await mcp.callTool("mail.send", {
to: ["client@example.com"],
subject: "Follow-up: Q4 proposal",
body: "Hi - attached is the updated proposal.\n\nLet me know if you have questions."
});curl -X POST https://app.ambi.cc/api/mail/send \
