Avoid Chaotic Slack Channels With a Setup Checklist
A new channel gets created but no one sets a description, pins key decisions, or defines who should be in it. Notis sends a WhatsApp checklist: description, topic, members, pinned items. Check them off.
Trigger
New Channel Created Trigger
Triggered when a new channel is created in Slack.
Action
Send message
Send a text message to a whatsapp number. note: the message will reflect on the recipient's phone number only if they have texted first.
Why this helps
Slack channels accumulate and become messy—duplicates, unclear purpose, lost context. Newer team members get confused about which channel to use when.
- Every channel has clear purpose and structure
- New members know what a channel is for
- Reduce channel sprawl and duplication
- Better discoverability within Slack
Setup
Build it in a few focused steps.
- 1Connect Slack and WhatsApp to Notis.
- 2Create automation: 'When a new channel is created in Slack, send a setup checklist on WhatsApp.'
- 3A new channel is created (or someone @-mentions Notis in an empty channel).
- 4Notis sends WhatsApp with checklist: 'Description? Topic? Members? Pinned decisions?'
- 5Check off items on WhatsApp; Notis applies them to the Slack channel automatically.
Questions about this workflow
What if the channel already has a description?
Notis checks Slack first. If it's set, Notis skips that checklist item.
Can I customize the checklist?
Yes. Tell Notis: 'Add 'External access' and 'Archive date' to the checklist.'
What if I don't have time to fill out the checklist?
Notis will re-send reminders or let the channel auto-archive if unused for 30 days.
