Why teams run it

Teams see which campaign produced each positive reply without opening the Instantly Unibox.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.
Name it Get Slack alerts for positive Instantly replies with the campaign name.
Set the trigger to Incoming Message and choose Instantly mailboxes.
Add a condition: Label sentiment is positive.
Add the action Notify in Slack: Post the campaign name, prospect, company, reply and thread link to #sales.
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. This workflow also uses conditions: add them under trigger_config.conditions, as shown on the conditions page.

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": "Get Slack alerts for positive Instantly replies with the campaign name",
  "trigger_type": "incoming_message",
  "trigger_config": {
    "channel_ids": [
      "-1"
    ]
  },
  "action_configs": [

      "action_type": "slack_notify",
      "payload_variables": [
        "name",
        "company_name",
        "label_names",
        "text",
        "thread_url"
      ],
      "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: "Get Slack alerts for positive Instantly replies with the campaign name". 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 if the AI label lands a moment after the message?

Turn on Retry on condition failure. A failed condition is checked again after 2 and 5 minutes, which covers the time AI labeling needs.

Which replies count as positive?

Any label you mark as positive sentiment, for example Interested, Meeting request or Information request.

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.
