Why this helps

Renewal decisions are clear in Slack but relationship care is inconsistent.

  • Builds a repeatable relationship habit
  • Uses a low-friction team signal
  • Supports partner retention

Setup

Build it in a few focused steps.

  • 1Connect Slackbot and Docupost once in Notis.
  • 2Create an automation named Reaction partner renewal postcard.
  • 3Tell Notis to recognize the chosen reaction on partner renewal messages, confirm addresses, and send approved postcard images.
  • 4Pick Message Reaction Added as the trigger.
  • 5Choose where reports go and test with one renewal reaction.

Questions about this workflow

Can different partner tiers use different designs?

Yes. Include tier rules and approved image URLs in the prompt.

What if the reaction is removed later?

This workflow responds to the added reaction event only.
