We source targeted mailing lists, email lists, and telemarketing data across 600 categories so you don't have to. One request, one point of contact, thousands of data sources.
Sourcing data on your own means contacting dozens of list owners, comparing formats, and managing multiple vendors. We handle all of that — and our service is free to you.
We earn our commission from the list owner, not from you. You pay the same standard CPM rate — our expertise costs you nothing extra.
Access 57,093+ data products from hundreds of list owners through a single point of contact. No vendor juggling.
Every file is NCOA/CASS processed and suppression-scrubbed. If deliverability falls below 95%, we make it right.
We merge, purge, deduplicate, and format your data across multiple list sources so you receive one clean, ready-to-use file.

List.Solutions is a full-service data brokerage operated by Lead Harmonics LLC. We act as your single point of contact for sourcing targeted consumer, B2B, and healthcare mailing lists from hundreds of data owners and compilers. Instead of contacting list owners individually, negotiating rates, and managing multiple vendors, you work with one team that handles everything — from list research and recommendations to data processing and delivery.
We source three main categories of marketing data: compiled lists (built from public records, surveys, directories, and business filings), response lists (individuals who have taken a specific action like purchasing a product, subscribing, or donating), and specialty lists (high-ticket buyers, hotline names, multi-buyers, and niche audience segments). Our team helps you determine which type best fits your campaign goals and budget.
Whether you need postal addresses for direct mail, verified email addresses for digital outreach, phone numbers for telemarketing, or matched records for programmatic advertising, we source and deliver data formatted for your channel. For multi-channel campaigns, we merge and deduplicate records across sources so your messaging stays coordinated and cost-efficient.
Browse the categories above to find your target audience, or simply tell us who you want to reach. We will research available lists, provide record counts and pricing, and recommend the best data sources for your campaign. For custom requests, multi-list orders, or ongoing data programs, call us at (321) 300-4912 or email info@list.solutions.
