Give customer renewals a personal thank-you
A renewal is a chance to thank a customer for choosing to continue working with you.
Trigger
Channel Message Received
Triggered when a message is posted in a Slack channel (public, private, or multi-party IM). Does NOT match direct messages.
Action

Tool to send a postcard via u.s. mail with specified recipient, sender, and front/back images. use after confirming recipient addresses and design urls. example: send postcard(to name='john doe', ..., front image='https://...', back image='https://...')
Why this helps
Renewals are often treated as admin events, so the relationship-building follow-up gets missed.
- Connect a renewal milestone with appreciation.
- Make retention follow-up easier to remember.
- Verify recipient and approved postcard artwork.
Setup
Build it in a few focused steps.
- 1Connect Slack and Docupost to Notis once in the portal.
- 2Set up an automation in the portal or ask Notis conversationally.
- 3Give Notis one instruction to prepare a thank-you postcard after a confirmed renewal and check recipient, address, and design.
- 4Select Slack Channel Message Received, choose a channel for run reports, and test with one real renewal update.
