Action
Send Post Letter
Tool to send physical letters through ClickSend's postal service. Use when you need to send a PDF document as a physical letter to one or more recipients. For docx/doc files, convert them first using /uploads?convert=post endpoint.
Why this helps
A prepared letter can stall while someone downloads it, re-enters addresses, and moves between tools to mail it.
- Move a ready PDF into a postal workflow with fewer manual steps.
- Reuse recipient details supplied in the document or instruction.
- Keep postal follow-up connected to the document workflow.
Setup
Build it in a few focused steps.
- 1Connect Google Drive and ClickSend once in the Notis portal.
- 2Create an automation in Automations, New Automation, and give it a name.
- 3Tell Notis in one instruction which new PDF to send and provide the recipient and return address details.
- 4Choose the Google Drive File Created trigger and where run reports should go.
- 5Test with one real PDF and verify the address and document before sending.
Questions about this workflow
Can any Drive file be mailed?
This workflow is for a PDF intended as a letter. ClickSend requires DOCX or DOC files to be converted first using its post upload endpoint, so use a PDF for this workflow.
Where do the mailing addresses come from?
They must be available in the document or supplied in your instruction. Notis cannot infer missing recipient or return address details.

Calculate Post Letter Price

File Deleted or Trashed

Calculate SMS Campaign Price
Tool to calculate the price for an SMS campaign before sending. Use when you need to estimate costs for an SMS campaign to a contact list. Pricing depends on the number of recipients, message length, and destination countries.
File Shared (Permissions Added)
Triggers when new sharing permissions are granted to a file or folder. Uses Drive's `changes.list` endpoint with inline `permissions` in the `fields` mask so each change carries the file's current permission set provider-atomically. We diff that against `seen_permission_keys` to identify newly added grants. Drive page tokens are the primary cursor; if Drive rejects a stored token, the trigger raises `PollingTriggerError` without clearing state rather than silently re-baselining and dropping events. Limitation: truly ephemeral permissions (added and revoked between two polls without any other file modification in between) are not detected. Drive Activity API would catch those but requires an additional OAuth scope and a different payload contract.
