Send mail from a Google Forms submission
Mail a confirmation letter or signed contract straight from a form response: pair Google Forms’ own Zapier, Make, or n8n trigger with paperplane’s Send Letter action, mapping the submitted fields into the letter — from $1.99.
Via Zapier, Make, or n8n — no direct app yet
Instead of a confirmation email
A confirmation email lands in a promotions tab. A mailed confirmation, receipt or contract gets opened, and the trigger you would use for the email is the same one that feeds the letter.
How to set it up
- 1In Zapier, Make, or n8n, use the Google Forms "New Response" trigger on the form you want to act on.
- 2Add the paperplane Send Letter action and map the response fields (name, address, and any free-text answers) into the letter text or address fields.
- 3Sandbox-test with a real submission first — free, instant, nothing mailed.
- 4Go live; every new response mails itself, with the order id available to write back to a linked Sheet if you also track responses there.
What the action sends for a new response
{
"mail_class": "first_class",
"sandbox": true,
"text": "Dear Ms. Alvarez, ...",
"to": { "name": "Maria Alvarez", "line1": "1 Main St",
"city": "Richmond", "state": "VA", "zip": "23220" },
"from": { "name": "Alex Rivera", "line1": "12 Grove Ave",
"city": "Richmond", "state": "VA", "zip": "23221" },
"email": "alex@example.com"
}Under the hood
Google Forms responses land in a Sheet by default, so this is the same row-to-letter mapping as the Google Sheets pairwise page, triggered directly off the form instead of the sheet. No paperplane-specific Forms app exists — this pairs Google’s own well-supported trigger with the standard Send Letter action.
Supported action fields
Every integration maps into the same fixed set of fields, the ones the REST API and MCP tools take directly.
| Field | What it does |
|---|---|
| mail_class | first_class, certified, certified_return_receipt, or priority |
| text or pdf_url | the letter body as plain text, or a fetchable PDF to print as-is |
| to | recipient name + street/city/state/zip, verified against USPS data |
| from | return address, printed on the envelope and used for undeliverable mail |
| where the receipt and status updates go — no account required |
Popular Google Forms workflows
Or skip the automation tool: ask Claude or ChatGPT
Every integration here sits on the same MCP endpoint agents use directly. Instead of wiring a trigger to an action, ask Claude or ChatGPT to draft and mail the letter. Same three tools (quote_letter, send_letter, get_letter_status), same price, same free sandbox.

}'Common questions
Does the form need a specific question layout?
No fixed layout is required, but a form with separate fields for name, street, city, state, and zip maps far more cleanly into the address object than a single free-text "your address" question.
Can I mail a signed contract, not just a confirmation?
Yes — if the form (or a follow-up e-signature step) produces a fetchable PDF, map that into pdf_url instead of building the letter from text fields.
What happens if a respondent leaves the address incomplete?
USPS verification runs before payment on every order; an incomplete address returns a structured error instead of mailing, so the automation can flag that response for follow-up.
