Why this helps

Good intentions to thank important clients can get buried under the next urgent task.

  • Keep appreciation from disappearing in a busy channel.
  • Use a real mailed letter for a personal client touch.
  • Confirm the recipient and letter details before sending.

Setup

Build it in a few focused steps.

  • 1Connect Slack and Docupost to Notis once in the portal.
  • 2Create an automation in the portal or ask Notis for one in plain language.
  • 3In one instruction, describe when to prepare a client thank-you letter and require confirmation of recipient and document details.
  • 4Choose Slack Channel Message Received as the trigger, select a channel for run reports, and test with one real example.

Questions about this workflow

Will every Slack message send a letter?

The automation should act only when a message clearly describes an approved client thank-you. Have Notis confirm the recipient and document details before sending.

Can the message itself contain the letter?

Your instruction can ask Notis to use relevant message context, while checking that the final letter document and mailing details are available.
