Why this helps
Research sessions are valuable, but participant thanks can be forgotten once analysis begins.
- Tie a thank-you to a completed research session.
- Help participants feel their contribution mattered.
- Check the recipient address and postcard design.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docupost to Notis once in the portal.
- 2Create the automation in the portal or ask Notis for it in plain language.
- 3Write one instruction that uses a chosen reaction on a completed research note to prepare a postcard and confirm recipient and design details.
- 4Select Message Reaction Added with the intended channel or emoji filter, choose a run-report channel, and test with one completed session.
Questions about this workflow
Can this be used after an interview?
Yes. Use a completed-session Slack note and a specific reaction as the cue to prepare the postcard.
Can the participant's address be assumed?
No. Ask Notis to confirm the mailing address and postcard images before sending.
