Why this helps
After resolving an urgent issue, teams often move on before sending the promised follow-up.
- Capture follow-up commitments made in a DM.
- Give customers a clear written closeout.
- Check the intended recipient and letter before sending.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docupost to Notis once in the portal.
- 2Create an automation through the portal or ask Notis to create it in plain language.
- 3In one instruction, ask Notis to prepare a letter only when a customer resolution is confirmed and to verify recipient and document details.
- 4Select Direct Message Received, choose a channel for run reports, and test with one real resolution update.
Questions about this workflow
Does this include every DM?
The trigger catches DMs across Slack DM channels. Describe the resolution cue clearly so Notis acts only on relevant messages.
Should the letter contain sensitive account details?
Keep the instruction limited to appropriate correspondence and confirm the final letter before it is sent.
