Telemarketing, Data Building & Lead Generation Specialists

Database Building & Validation for Marketing & Lead Generation

Poor quality or ‘dirty’ data means wasted time and money, inefficiency and slower results. Managing and updating your data accurately, regularly and legally enhances the possibility of generating profitable new business.

Regular database cleaning & validation are critical for effective lead generation. Accurate list gathering and data building are essential to any outbound direct marketing or telemarketing campaign. Whether you use LinkedIn for lead generation and data gathering or Google to research names and companies, good, reliable data is the platform for a successful telemarketing campaign.

  • Gathering consent – informed and unambiguous consent is increasingly required for marketing. We can gather consent using recorded calls and date and time stamped information
  • List Building — generate a bespoke list of prime targets through any combination of list gathering, online research and phone validation.
  • List Validation — the only effective way to update business data is to telephone each record.  Using telemarketing research to add or validate contact names, phone numbers, addresses, email addresses on your current marketing lists.
  • Data Cleansing — using a variety of processes to clean your data to ensure consistency, uniformity, uniqueness (de-duplication) of your data
  • Opt-out screening — against the telephone and mailing preference services to meet your legal responsibilities and prevent you falling foul of legislation.
  • List Purchase — List sourcing through quality list providers and brokers.*

*Note: we are not a list broker and do not offer a list broking service. List purchase is carried out as part of a broader campaign.
