Close the loop after an agreement is signed
A signed agreement is a natural point to send a clear, formal confirmation by mail.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action
Send Letter
Tool to send a letter via u.s. mail with specified recipient, sender, and pdf. use after confirming recipient and document details. example: send letter(to name='john doe', to address='123 main st, ...', file url='https://...')
Why this helps
The team may celebrate a signature but forget the administrative follow-through.
- Tie a clear business event to its follow-up.
- Keep formal correspondence from being lost in Slack.
- Check the recipient and final document before mailing.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docupost to Notis once through the portal.
- 2Create the automation in the portal or ask Notis to set it up conversationally.
- 3Write one instruction to prepare a confirmation letter only for a signed-agreement update, with recipient and document confirmation required.
- 4Select Slack Channel Message Received, choose where run reports should go, and test with a real signed-agreement update.
Questions about this workflow
Can this send legal documents automatically?
The instruction should limit the workflow to the intended confirmation letter and require the correct final document and recipient to be confirmed.
Which Slack event should I select?
Choose Channel Message Received for the channel where signed-agreement updates are posted.
