Re-engage quiet LinkedIn positives with a HeyReach follow-up campaign

Five days after your team replies on LinkedIn, if the prospect has not answered, Master Inbox adds them to a HeyReach follow-up campaign so the conversation gets a gentle nudge.

Warm LinkedIn threads die quietly when nobody follows up.

Set it up in Master Inbox

In Master Inbox, open Settings, then Workflows, and click Add a workflow.

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": "Re-engage quiet LinkedIn positives with a HeyReach follow-up campaign",
  "trigger_type": "send_message",
  "trigger_config": {
    "channel_ids": [
      "-1"
    ]
  },
  "action_configs": [
    {
      "action_type": "add_to_sequence_heyreach",
      "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: "Re-engage quiet LinkedIn positives with a HeyReach follow-up campaign". 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 the AI follow up instead?

Yes. A LinkedIn reply agent can follow up on positive threads on a schedule.

Will it add someone who replied?

No. If the prospect replied, the last message condition fails.

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.
