Lead source · CSV import

Bring your existing list. Duplicates merge instead of doubling.

Moving from a spreadsheet or another CRM? Upload the export: common column names — name, mobile, phone, email, company, product, country — are detected automatically, and rows that match an existing lead by phone or email merge into it.

  • A CSV export with a header row
  • Contact fields that can identify a lead
  • A reviewed source list you are authorised to store and contact

What this connection makes possible.

An import never messages anyone by itself. Reaching an imported list is a campaign you start on purpose, with approved templates for anyone outside the 24-hour window.

  • Column detection for common CRM and marketplace exports
  • Merging by phone and email, including within the same file
  • A source column becomes a tag, so each list can be targeted later
  • Import history showing the batch each lead came from
  • Export back to CSV at any time — your data is never locked in
  • Imports never trigger outreach on their own

Connect & verify

Set it up, one step at a time.

  1. 01

    Export from where the leads are now

    Any CSV with a header row works; the columns above are recognised by name.

  2. 02

    Upload

    Import → choose the file. The summary shows how many leads were created, merged or skipped.

  3. 03

    Start a campaign when ready

    Campaigns → New, filtered to the leads you just imported.

Check the whole connection

Check the import summary and a sample of the resulting lead records before preparing any outreach.

FAQ

CSV import questions

Will importing send messages?

No. Imported leads wait for a campaign you review and start. Live-source first contact is a separate flow that depends on eligibility and your outreach settings.

Can AI agents import leads too?

Yes. The MCP server has an import tool, so Claude or another MCP client can add a list you give it, with the same merging rules.
