Remove not interested replies from EmailBison and block them
When a reply is labeled Not interested, Master Inbox removes the lead from the EmailBison campaign. Mark the label as DNC in the EmailBison integration and the lead is blocklisted too.

Why teams run it
People who said no are not emailed again by the next campaign.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Remove not interested replies from EmailBison and block them.
- Set the trigger to Add Label and choose Not interested.
- Add the action Remove from EmailBison campaign: The lead's active campaigns.
- Save the workflow and switch it to Active.
Before you start, connect EmailBison 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.

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: "Remove not interested replies from EmailBison and block them". 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 block the whole domain?
Yes. The DNC label settings include an add domain to blocklist option.
What if the AI labels wrongly?
Remove the label and re-add the lead to the campaign. Workflows only act on new label changes.
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.
