Move opted-in leads from Slack into Doppler
A clear Slack handoff can become a subscriber record without interrupting your next task.
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
Add Subscriber
Tool to add a new subscriber to a specific list for a specified account.
Why this helps
Leads shared in busy channels can get buried before anyone adds them to the right list.
- Capture only contacts whose email and permission to subscribe are explicit.
- Reduce repetitive copying between Slack and marketing tools.
- Keep lead handoffs moving without switching out of current work.
Setup
Build it in a few focused steps.
- 1Connect Slack and Doppler to Notis once in the portal.
- 2Create an automation in the portal or tell Notis what outcome you want in plain language.
- 3Instruct Notis to add a Slack-shared contact to a specified Doppler list only when the email and consent are explicit.
- 4Select Slack Channel Message Received as the trigger and choose where run reports should go.
- 5Test with one consented lead in a channel and check the Doppler list.
Questions about this workflow
Will every email mentioned in Slack be added?
The instruction should require a clearly stated subscription permission and a specified list; ambiguous mentions should be skipped.
What if the message has no email address?
Notis should skip the record rather than infer or search for contact details.
