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.

Here's what they say about us:

“GSA Marketing worked with us on a test campaign to assess the viability of an outbound sales function in what is a relatively niche sector (outdoor learning residential breaks for Special Educational Needs schools) for our centre in the Lake District. The target market was Teachers or Special Needs Coordinators within schools and colleges, with us providing contact details, albeit un-validated, from our existing database – a combination of organisations who had enquired but never visited, or lapsed. We asked them to pitch for our business from a shortlist of potential suppliers and we chose them due to the bespoke attention they paid to our enquiry, and once selected were very pleased with the personal attention they gave us at a senior level. Setting up the campaign with them was very straightforward and we were impressed by the level of reporting through the campaign and the quality of the calls made by their staff, with each call being recorded. Warm leads were passed to us to follow-up and the quality of the contact information supplied very good. The nature of our business is that 1st contact to booking is usually relatively long, but we were delighted that the month long… Justin Farnan, Business Manager (Sales and Marketing) Lake District Calvert Trust
"Expectations Exceeded! On the second day of our campaign we were simply delighted to get a call from Tonie telling us that she had secured two appointments for us with organisations that exactly matched our brief. Our initial view of GSA was that we were clearly dealing with experts in their field — this early on in our campaign our high expectations have already been exceeded and we are over the moon with how quickly Tonie has become an integral part of our team."
