About us

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.

Our Values

Organizations can often be guilty of having a page of values on their website because they think they need one. At GSA, we don’t take this lightly and our values page is not just for show. We live the values in every interaction with our clients and our testimonials demonstrate that we bring these to every lead generation campaign.

Give us a call and we’ll be delighted to explain more, and check out our Service Standards for more insight as to what it’s like to work with GSA.

Pragmatic Advice

Our experience spans several decades. So, we’ve seen a campaign or two. Therefore, when we provide advice, it’s grounded in reality. And, we have plenty of KPIs to back up what we say.
