Move a prepared subscriber batch into Doppler
Complete a deliberate batch handoff without copying each eligible contact by hand.
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
Import Subscribers
Tool to import multiple subscribers into a specific list in bulk. use when you need to add or update a batch of subscriber records after preparing the data.
Why this helps
Bulk imports can linger as unfinished work when the details are scattered across messages and files.
- Reduce repetitive handling of prepared subscriber batches.
- Keep the destination list explicit in the handoff.
- Require consent before importing contact records.
Setup
Build it in a few focused steps.
- 1Connect Slack and Doppler to Notis once in the portal.
- 2Create the automation in the portal or tell Notis in plain language to import a prepared subscriber batch into Doppler.
- 3Specify how the message identifies the batch, the destination list, and explicit subscription consent for every contact.
- 4Select Slack Channel Message Received as the trigger and choose where run reports should go.
- 5Test with one small, consented batch and confirm the Doppler result.
Questions about this workflow
Can Notis import a batch from any Slack attachment?
Only when the batch is accessible to Notis and the instruction identifies it and its destination clearly.
Should a batch include contacts without confirmed permission?
No. The instruction should exclude contacts whose permission to subscribe is unclear.
