Notis

Close the loop after a difficult customer issue

A thoughtful written follow-up can reassure a customer once the team has resolved an issue.

Trigger

Direct Message Received

Triggered when a new direct message (DM) is sent to a user in Slack. Catches all DMs across all DM channels.

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

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.
