Why this helps
Signup requests and consent checks can be scattered across chat, making it easy to miss an approved subscriber.
- Use an intentional reaction to signal approval.
- Keep the address and consent context together in Slack.
- Avoid copying approved subscribers by hand.
Setup
Build it in a few focused steps.
- 1Connect Slack and Benchmark email to Notis once.
- 2Create an automation through the portal or by asking Notis in plain language.
- 3In one instruction, specify the approval reaction, the Benchmark list, and that only confirmed, consented email addresses should be added.
- 4Choose the Slack reaction-added trigger and select a run-report channel.
- 5Test by reacting to one real, consented subscriber message and verify the contact.
Questions about this workflow
Can a reaction alone provide a subscriber email?
No. The message or accessible context needs to contain a confirmed address and clear permission to subscribe.
Can I choose which reaction means approval?
Yes. State the emoji and any channel context in the plain-language instruction.
