Why this helps
A campaign can be ready to send but sit waiting while the final approval gets lost in team discussion.
- Connects an explicit approval signal to delivery.
- Reduces waiting after the team makes its decision.
- Keeps the target campaign identified in the review context.
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 to set it up conversationally.
- 3In one instruction, specify the approval reaction and require the message to identify a campaign that exists, has recipients, and is ready for immediate sending.
- 4Choose the Slack reaction-added trigger, select the run-report channel, and test with a real approval on a ready campaign.
Questions about this workflow
What must be true for the send action to work?
The campaign must exist, have at least one recipient, and not already be scheduled or delivered.
