Alert a reviewer in Slack when an AI draft is held for review

When the reply agent holds a draft instead of sending it, Master Inbox posts the hold reason, the prospect and the thread link to a QA channel in Slack, so held drafts never sit unseen.

Why teams run it

Held drafts are replies a prospect is waiting for, and they get lost across workspaces.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Alert a reviewer in Slack when an AI draft is held for review.
Set the trigger to Draft Held and choose Any hold reason.
Add the action Notify in Slack: Post the hold reason, prospect and thread link to #ai-review.
Save the workflow and switch it to Active.

Before you start, connect Slack under Settings, Integrations.

Or create it with the API

Everything in the workflow builder is also in the Master Inbox API. This request creates the same workflow. Replace the example ids with your own label, list and campaign ids from GET /workflows/filter-fields.

curl -X POST https://api.masterinbox.com/api/api-webhook/v1/api/workflows/create-workflow \
  -H "Authorization: Bearer $MASTER_INBOX_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
  "name": "Alert a reviewer in Slack when an AI draft is held for review",
  "trigger_type": "draft_held",
  "trigger_config": {},

      ],
      "show_draft": true
    }
  ]
}'

Or ask Claude, ChatGPT or Grok to build it

Our workflow guide is written for AI agents to read. Give your assistant your API key and this prompt:

Read https://app.masterinbox.com/public-workflow-api.md and use my Master Inbox API key to create this workflow: "Alert a reviewer in Slack when an AI draft is held for review". First call GET /workflows/filter-fields and look up my label, list and channel ids, then create the workflow and tell me what you set up.

Questions

What are the hold reasons?

They include unsafe draft, reply need unresolved, duplicate follow-up content, calendar approval pending and blocked quality, among others.

Can I alert only on some reasons?

Yes. Pick the hold reasons on the trigger.

Can I build this workflow through the API?

Yes. Send the create-workflow request shown on this page with your Master Inbox API key. The API checks the payload first and lists every problem by field if anything is off.

Which plan includes this?

This workflow works on the Team plan. Every plan has unlimited users and starts with a free 7-day POC.
