Keep interested testers in the loop without maintaining a separate follow-up list.
Trigger

Action
Insert Subscriber

Why this helps
Beta interest can arrive amid product discussion and disappear before someone adds the person to the mailing list.
- Captures explicit requests for beta updates.
- Saves manual copying from product conversations.
- Keeps verification before subscriber insertion in the process.
Setup
Build it in a few focused steps.
- 1Connect Slack and Enginemailer to Notis once in the portal.
- 2Create the automation in the portal or ask Notis in plain language.
- 3Use one instruction to add only people who clearly request beta email updates and provide a verifiable address to the designated beta list.
- 4Select the Slack channel-message trigger, choose the run-report channel, and test with one genuine opt-in.
Questions about this workflow
Does mentioning the beta count as consent?
