Send mail from HubSpot

Trigger a real, mailed letter from a HubSpot contact or deal: pair HubSpot’s own Zapier, Make, or n8n trigger with paperplane’s Send Letter action — a welcome letter or contract goes out from $1.99, no paperplane account needed.

Via Zapier, Make, or n8n — no direct app yet

Instead of a HubSpot sequence

Sequences send email. A welcome pack, a signed agreement or a cancellation notice lands harder on paper, and the same HubSpot trigger you would use for the email step feeds the Send Letter action instead.

How to set it up

1In Zapier, Make, or n8n, start from a HubSpot trigger — New Contact, Contact Property Change, or Deal Stage Changed all work.
2Add the paperplane Send Letter action and map the contact/deal fields (name, address, and whatever letter text or template you want) into it.
3Leave Sandbox on for the first run — free, instant, and nothing is mailed while you check the mapping.
4Go live. Pay from a prepaid credit balance for hands-off sending, or approve the Stripe link per letter.

What the action sends for a new contact

{
  "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

There’s no paperplane-specific HubSpot connector today — this pairs HubSpot’s own well-supported Zapier/Make/n8n triggers with the same Send Letter action every other integration on this page uses. If HubSpot’s address fields are split across multiple properties, map them into the to object’s line1/city/state/zip fields individually.

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
email	where the receipt and status updates go — no account required

Popular HubSpot workflows

HubSpot → welcome letter

A new contact is created in HubSpot (or added to a specific list).

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 paperplane have a native HubSpot app?

Not yet — today this runs through HubSpot’s own trigger in Zapier, Make, or n8n paired with paperplane’s Send Letter action, the same pattern as every trigger app not yet natively listed.

Can I mail a letter only after a deal reaches a certain stage?

Yes — use HubSpot’s "Deal Stage Changed" trigger, filter to the stage you want, then map the deal and its associated contact into the Send Letter action.

What if the contact record is missing a full mailing address?

Every order is USPS-verified before payment; an incomplete address returns a structured error instead of mailing, so the automation can skip or flag that contact.
