The native way to send mail

Before any third-party tool, paperplane is itself a front door for physical mail: compose on the web, send from an email, or hand it to Claude or ChatGPT — all three hit the same order engine, from $1.99 First-Class.

Web composer

Live

Paste text or upload a PDF, address it, and pay — no account required. This is the surface every other surface on this site ultimately calls into.

Compose a letter →

Text/SMS

Live

Text a recipient and a letter — in plain language, or the same TO: block convention as email, or a shared Contact card — and get a quote back. Nothing mails until you reply with an explicit yes.

Email-to-send

Live

Start the email body with a TO: block naming the recipient, then the letter text. Forward to our inbound address, get a quote, reply to confirm and send.

MCP / agent access

Live

This is paperplane’s actual differentiator, not a bolt-on: one MCP endpoint (/api/mcp) exposes quote_letter, send_letter, and get_letter_status to any MCP-compatible assistant — Claude, ChatGPT, Cursor — with a free sandbox and a human-approved payment link for every live send.

Tell your agent:

Using the paperplane tools, quote a 1-page certified letter to Property LLC, 1 Main St, Richmond VA 23220, then send it in sandbox mode.

Already have data living in another tool — a spreadsheet, a database, a form? That’s what the third-party integrations directory is for: Zapier, n8n, Make, Google Drive, Dropbox, and more, all built on the same {quote_letter, send_letter, get_letter_status} engine as the native surfaces above.

Common questions

What’s the difference between a native surface and an integration?

A native surface is paperplane itself — the web composer, email-to-send, and MCP/agent access are how you use the product directly. An integration (Zapier, n8n, Make, a file picker) is a third-party tool that calls into one of these surfaces on your behalf.

Is email-to-send live today?

Yes. Forward an email with a recipient and letter text to our inbound address, get a quote, and reply to confirm and send.

Can I text paperplane on iMessage today?

Yes. Text a recipient and letter content to paperplane on iMessage, get a quote back, and reply to confirm and send.

Which AI assistants can send mail through MCP?

Anything that speaks MCP — Claude Desktop, Claude Code, ChatGPT (as a custom connector), Cursor, and other MCP-compatible clients — all through the same endpoint, so capabilities stay identical across assistants.
