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.

  • 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.*

Here's what they say about us:

Right from the start GSA understood the needs of our cross-Europe tele-research campaign fully & were able to advise and adapt to our specific requirements. The daily reporting helped us understand, first-hand, how the campaign was progressing and help keep costs within the allocated budgets. They were very flexible in terms of the native speakers used as subsequent data was added to the project. I would highly recommend them and will certainly be using them for other projects” Damian Jackson – Insights Analyst EMEA OKI Europe Ltd
"Just a short note to say thank you for all the hard work that GSA has done for our business over the last couple of years. The team on our business has always been very in tune with the agency. We have found GSA to be very effective at representing us on the phone and in fixing new business meetings. I would be delighted to recommend your services to others and to use you again in the future." Managing Director Advertising agency
