Send not interested replies to your warehouse to find objection patterns
When a reply is labeled Not interested, a webhook sends the reply text, campaign and company to n8n, which writes it to BigQuery, Snowflake or Postgres for objection analysis.
Why teams run it
Objections tell you which copy, offers and segments to change, but only if you can query them.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Send not interested replies to your warehouse to find objection patterns.
- Set the trigger to Add Label and choose Not interested.
- Add the action Send a webhook: Send the reply text, campaign name, company and job title to n8n, which writes it to your warehouse.
- Save the workflow and switch it to Active.
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 \

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: "Send not interested replies to your warehouse to find objection patterns". 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
Can I include custom fields from Clay?
Yes. Custom fields are available as payload variables.
Can I backfill older replies?
Workflows only act on new events. Pull history with the get-replies API endpoint.
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.
