Stop the Smartlead email sequence when a prospect replies on LinkedIn

When a HeyReach LinkedIn reply is labeled positive, Master Inbox removes the lead from the Smartlead campaign, so cold emails stop once the conversation is live on LinkedIn.

Why teams run it

Sequencers cannot see LinkedIn replies, so they keep emailing people who already said yes.

Set it up in Master Inbox

  1. In Master Inbox, open Settings, then Workflows, and click Add a workflow.
  2. Name it Stop the Smartlead email sequence when a prospect replies on LinkedIn.
  3. Set the trigger to Add Label and choose Interested or Meeting request.
  4. Add a condition: Source is HeyReach.
  5. Add the action Remove from Smartlead campaign: The lead's active campaigns.
  6. Save the workflow and switch it to Active.

Before you start, connect Smartlead 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": "Stop the Smartlead email sequence when a prospect replies on LinkedIn",
  "trigger_type": "add_label",
  "trigger_config": {
    "label_ids": [
      176479
    ]
  },
  "action_configs": [
    {
      "action_type": "remove_from_campaign_smartlead",
      "campaign_ids": [
        "camp-1"
      ]
    }
  ]
}'

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: "Stop the Smartlead email sequence when a prospect replies on LinkedIn". 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

Does it work for other LinkedIn tools?

Yes. Change the source condition to Aimfox, Expandi or lemlist.

Can I pause instead?

Yes. Use Pause in Smartlead.

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.
