Onboarding has many moving parts, and the personal welcome can fall through the cracks.
- Add a tangible welcome to the onboarding routine.
- Reduce the need to remember a separate mailing task.
- Check the letter and address before it goes out.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docupost to Notis once in the portal.
- 2Create a portal automation or ask Notis to create one conversationally.
- 3Give Notis one plain-language instruction to prepare a welcome letter for a new-client announcement and verify recipient and document details.
- 4Select Slack Channel Message Received, choose a channel for run reports, and test with one real announcement.
Questions about this workflow
Can this run only for client announcements?
Describe the announcement cue in the plain-language instruction and select the Slack channel where those announcements appear.
Will it mail a letter immediately?
Include a requirement for Notis to confirm the intended recipient and document details before using the Docupost send action.
