List → Call list · n8n

Find mobile numbers – and call only reachable contacts.

For contacts who fit your target profile, ListPlus looks up the mobile number – charged only on a hit. The “Reachable” column shows who you can call today.

Setup

Build this workflow.

A list with names and companies (better: LinkedIn URLs) and a fit score or filter that defines the target contacts. A pipeline to n8n, Sheets or the CRM for the call list.

What does a run cost?

The mobile number per contact: expected 3.84 credits, at most 12 credits ($0.42 on Pro) – charged only on a hit. The number checks and “Reachable” cost nothing.

  1. ListPlus by call

    Select the target contacts

    Only rows with a fit score of 80 or more and no number – phone is the thinnest data layer, so select first, look up second.

  2. ListPlus runs automatically

    Look up the mobile number

    Several providers in turn; the price comes first, only a hit is charged. The lookup keeps running as a rule for every new matching contact.

  3. ListPlus runs automatically

    Check the number

    The checks flag dialling codes that do not fit the country and landlines where a mobile was expected – at no credit cost.

  4. ListPlus runs automatically

    Mark as reachable

    The “Reachable” column shows per row which channels are open. Hits get the status “Call”.

  5. n8n · CRM runs automatically

    Hand off the call list

    The pipeline hands “Call” rows to n8n, Sheets or the CRM – with reason and source per contact.

With your agent

Give your agent this brief.

A list of target contacts and a configured pipeline. An agent needs the “Full” right on the list for enrichment.

The same call from Claude Code, ChatGPT, Cursor or an n8n HTTP node – MCP and REST offer the same tools.

Agent guide (.md) ↗
Agent prompt

In “Trade show leads”: which rows with fit score ≥ 80 have no mobile number? Estimate the cost for mobile_phone and start with at most 40 credits. Set hits to status “Call” and hand them to the pipeline “n8n call list”. Rows without a hit stay as they are.

Try it with your data

Phone data is the thinnest layer in B2B data; expect fewer hits than for email. A number is a provider's hit, not proof the person still works there. Check local rules for cold calls before you dial.
