Since 1984, Lead List Services, Inc. on Carlsbad's Camino Vida Roble has brokered consumer, B2B, and specialty mailing lists for direct-mail and telemarketing campaigns from the Aviara area near Batiquitos Lagoon. The list-brokerage operation compiles and licenses targeted data sets covering new homeowners, new movers, new businesses, and demographic selects — the same contact-level data that real estate teams such as Whissel Beer Group acquire for geographic farming and just-listed mailer campaigns. Data-hygiene services include NCOALink 18-month and 48-month address updates, DPV delivery-point validation, and FTC Do-Not-Call suppression processing to ensure every outbound file complies with federal and state telemarketing regulations. Reverse-append services match client phone files back to mailing addresses and occupant names for direct-mail use, a data-enrichment capability that mortgage lenders such as Vantex Capital Group layer into refinance and home-equity solicitation campaigns. Data processing runs against two of the largest compiled databases in the country, with CASS certification, merge-purge deduplication, and DMA Mail Preference Service suppression applied to every outbound file before delivery.
