Telemarketing, Data Building & Lead Generation Specialists

Why should you use GSA for your outbound calling?

Our clients tell us that amongst the reasons they work with us is that we provide sound and unbiased advice and that we offer a no surprises approach with transparency that’s hard to find elsewhere. That means we work in partnership with our customers to never over-promise and under-deliver.

Our management team first seeks to understand clients’ business and what they’re trying to achieve before suggesting whether we can help. The support we offer could be for a traditional telemarketing campaign, database building, customer research or running a telemarketing training course. It could also extend to lead generation via LinkedIn.

We offer an intelligent approach to cold calling and lead generation. Reinforced by fantastic reporting and high levels of communication, this provides a recipe for success.

Our Telemarketing Team

We carefully select our telemarketers and reject more than we take on board. Our UK team is made up of high-quality individuals that we train for each campaign. No students or jobbing actors. Just mature, committed individuals that want to make a difference for our clients. They are therefore able to ‘engage’ and have peer to peer conversations with prospective clients to build rapport and identify their company problems (Pain) or opportunities (Gain) that our clients can resolve. That ensures that they deliver quality appointment setting for our clients.

Our clients have direct contact with their telemarketers and benefit from dedicated callers that operate seamlessly as part of their sales team. They also represent our clients’ business how they would like it presented.

In addition to our UK team, we have identified carefully chosen partners to allow GSA to offer larger scale multi-lingual telemarketing capabilities. We have carried out a number of successful international campaigns for large global organisations.

We our customers

Here's what they say about us:

"We started the session with an loose idea of how we wanted to progress our marketing campaign and what industries we wanted to target. By the end of the meeting Jonathan managed to turn me away from what I thought was the quickest and most direct approach! and also made me see the size of the mountain we had to climb. Sensing me thinking ‘oh-my-god’ he ensured we had the bare bones of practical approach for the climb and also let me know that I was supported along this journey. Jonathan managed to ensure that the ‘fluff’ of marketing was distilled into actionable tasks and offered an approach not just ideas." Managing Director Systems company
“GSA took on board our comprehensive brief and provided an excellent service from campaign inception through to analysis upon completion. We were particularly impressed by the professionalism and telephone manner of Julia March in conducting the calls to medical staff. Julia was quick to understand our technology and the correct terminology to use, with her distinct conversational tone helping to sell the benefits and uses of our speech privacy systems rather than focusing on the product. Likewise, the communications from both Julia and Kevin Harmsworth throughout ensured we remained fully up to date with progress, even when the campaign was temporarily put on hold to garner better results later in the year.” Steve Rees-Smith, Marketing/PR Vaughan Sound Installations Ltd
"Just wanted to thank you for the excellent training course ‘Making Yourself Indispensable to Your First Employer’ that you recently carried out at Hindhead Campus. The students found this extremely interesting and inspiring, and some very powerful messages were put across that will be very valuable to them as they enter the world of work. We had glowing reports about the training day, including many of the students saying they would like to work for you!!! There was a lot of content in the course, which the students acknowledged, but they said that the variation and enthusiasm you put into the day enabled them to keep focussed and on track. Thanks again for the time and effort you put into creating and organising this unique training ‘Boot-Camp’ day, and we would strongly recommend the course to other schools." Careers Manager Focus School
