Approvals Trigger Sends
You draft an email in Gmail and post it in Slack for approval. A teammate adds a checkmark emoji. Notis sees that and sends the email immediately. No extra action needed.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Send Draft
Sends the specified, existing draft to the recipients in the to, cc, and bcc headers.
Why this helps
Email approval workflows require manual handoffs. You draft, wait for approval in Slack, then remember to send. Steps fall through the cracks.
- Eliminate manual steps in approval workflows
- Reduce time from approval to sending
- Create a clear, visible approval process
- Empower team members to greenlight communications
Setup
Build it in a few focused steps.
- 1Connect Slack and Gmail.
- 2Create an automation: 'When someone adds a checkmark reaction to a Slack message, send the corresponding draft email.'
- 3Notis will match the Slack message to a Gmail draft (usually you'll link them manually first).
- 4Define which reactions trigger sends (checkmark, thumbs up, etc.).
- 5Test by posting a draft link in Slack and having a teammate react; the email will send.
Questions about this workflow
How does Notis know which email to send?
You provide the Gmail draft ID or link in the Slack message. Notis then waits for the approval emoji to trigger the send.
Can multiple approvals trigger one send?
Yes. You can require 2 or 3 approvals before Notis sends, adding extra confidence.
What if I want to reject and resend?
Set up a 'x' reaction to skip the send. Notis will pause and wait for the correct emoji.
