Smartlead

Smartlead sends to an email address, so ask for one in the request, for example Commercial cleaning companies in Phoenix, with the owner's name and email. SpecStream returns an email only when the business or person published it, and a record without one can't become a lead.

In SpecStream, select the records, click Export, and download a CSV. In Smartlead, open the campaign, choose Import Leads, then Import CSV, and map each column. Name and email map on their own, and other columns can become custom variables.

Smartlead's import can skip leads on your block list, unsubscribed leads, and leads already in another campaign. Choose those options before you upload.

Install the SpecStream node in self-hosted n8n, as the n8n guide shows. Start a workflow with SpecStream Trigger on Run Completed, then read the records with the SpecStream node's Get List Results.

Add an HTTP Request node. Set Method to POST and URL to https://server.smartlead.ai/api/v1/campaigns/<campaign ID>/leads?api_key=<your Smartlead API key>. Turn on Send Body, set Body Content Type to JSON, choose Using JSON, and enter the body below. Replace the field names with the column names in your list.

{
  "lead_list": [
    {
      "email": "{{ $json.Email }}",
      "company_name": "{{ $json.Business }}",
      "website": "{{ $json.Website }}",
      "custom_fields": { "source_url": "{{ $json.source_url }}" }
    }
  ]
}

To add leads as they appear, set the trigger's Event to Monitor Found New or Changed Records. In SpecStream, open the list, click Keep it current, choose how often it runs, and click Start monitor. Each run that finds something starts the workflow. Monitors covers cadence and limits.
