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": "Add positive leads who went quiet to a QuickMail follow-up campaign",
  "trigger_type": "send_message",
  "trigger_config": {
    "channel_ids": [
      "-1"
    ]
  },
  "action_configs": [
    {
      "action_type": "add_to_campaign_quickmail",
      "campaign_ids": [
        "camp-1"
      ]
    },
    {
      "action_type": "set_tag_quickmail"
    }
  ]
}'

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 positive leads who went quiet to a QuickMail 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

What should the campaign say?

Two or three short notes that reference their earlier yes.

Will it stop when they reply?

QuickMail stops on reply as usual, and the reply comes back into Master Inbox.

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.
