Add a lead to an Instantly nurture campaign when a rep moves them to Nurture
When a rep moves a thread to the Nurture list, Master Inbox adds the lead to your Instantly nurture campaign, so nurture starts with one drag.

Why teams run it
Reps decide who to nurture, and the sequencer does the rest.
Set it up in Master Inbox
- In Master Inbox, open Settings, then Workflows, and click Add a workflow.
- Name it Add a lead to an Instantly nurture campaign when a rep moves them to Nurture.
- Set the trigger to Moved to List and choose Nurture.
- Add the action Add to Instantly campaign: Nurture campaign.
- Save the workflow and switch it to Active.
Before you start, connect Instantly 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: "Add a lead to an Instantly nurture campaign when a rep moves them to Nurture". 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
How do I stop it if they re-engage?
Pair it with a Removed from List workflow that removes them from the campaign.
Can I move many leads at once?
Yes. A bulk move fires the workflow for each lead.
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.
