Why this helps
Community plans create small follow-ups that compete with founder priorities and get left behind.
- Creates a lightweight signal for a signup ready to process.
- Captures only messages with explicit email consent.
- Keeps community updates on a designated list.
Setup
Build it in a few focused steps.
- 1Connect Slack and Emailoctopus to Notis once in the portal.
- 2Ask Notis to create contacts from Slack messages marked with a selected reaction when they clearly opt in to community updates.
- 3Name the Emailoctopus list and require an email plus explicit consent in the prompt.
- 4Choose the Slack message reaction added trigger and the report channel.
- 5Test with one real opt-in message and the selected reaction.
Questions about this workflow
Can a reaction be used instead of asking for consent?
No. Treat the reaction as an internal processing signal only; the message must state that the person wants community email updates.
Does this trigger run when someone removes the reaction?
No. This workflow uses the message reaction added event.
