List Broker
A list broker is a third-party intermediary who sources, packages, and resells contact lists from underlying data owners — earning a margin between data-provider wholesale prices and end-buyer retail prices in the MCA and B2B lead market.
Why This Matters
List brokers fill a market gap: most data owners don't sell directly to small MCA shops, and most small shops can't negotiate volume contracts with primary data sources. Brokers aggregate, repackage, and distribute. The value-add varies — top brokers add data hygiene, deduplication, suppression scrubs, and segmentation; low-tier brokers simply mark up wholesale lists. When evaluating a broker, ask: who is your underlying data source, what's your refresh cadence, what suppression files do you scrub against, and what's your replacement policy for invalid records.
Frequently Asked Questions
Frequently Asked Questions
Should I buy from a list broker or direct from a data source?
Direct is cheaper at scale (10K+ records monthly) and gives data lineage transparency. Brokers are better for variety, smaller volumes, and turnkey segmentation. Many MCA shops use both — direct for core inventory, brokers for niche fills.
How do I evaluate list broker quality?
Run a sample of 100 records, dial them, and measure connect rate, accuracy of business details, and any returned mail. Compare against the broker's claimed accuracy. Walk away from any broker who can't disclose data sources or refresh cadence.
