Data Building Services & Data Validation for Marketing & Lead Generation

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

Regular database cleaning & validation is critical for effective business development. 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.


Accurate Data Building for Marketing Effectiveness

GSA offers a range of quality one-off or regular data building services in addition to data cleaning & data validation. These are tailored to your requirements so you can be sure that GSA data building services are the solution to all your marketing data issues.

B2B data is difficult to keep up to date at the best of times. There are so many changes within organisations every year. So, maintaining the quality and integrity of the data you hold can be a full-time task. What’s more it’s a case of ‘garbage in, garbage out. If your employees don’t update your system accurately, the data you hold can very quickly become worthless and you may not even know it.

Poor data is the main reason why sales lead generation fails to deliver

There’s nothing worse than sending an expensive piece of direct mail, making a call or sending an email to the wrong prospect. Yet, most prospect databases are inherently inaccurate so your efforts at keeping data up to date may fail through lack of attention.

Whatever your target market and decision maker, GSA will build you a shiny fresh new list that you can market to immediately.

Maximise Revenue with Effective Data Building Services

Data building should never be a one-off exercise. It’s an ongoing challenge. It’s a task that you should devote time to every day in your business. Data building and data validation should be the heartbeat of your marketing efforts. The better your prospect and customer data, the more likely you are to identify and win new customers for your business, retain current customers and to ensure that existing clients spend more on your products and services.

Regardless of your chosen method of marketing, without a robust database, your lead generation activities won’t hit their target and will fall on deaf ears. Effective email marketing, telemarketing, direct mail or LinkedIn marketing, can’t happen when you don’t get the right message to the right audience. So, make sure you give GSA a call if you need data building services to bolster your business development.

Data Building Services for Audience Targeting

Often, the focus for data building is on new prospecting targets. Yet, with frequent changes in management contacts within your customer base, how confident are you that you have the right contacts? Buyers come and go. For customers that perhaps buy from you infrequently, a new buyer may not have any relationship with your business. It’s crucial, therefore, to keep on top of changes so that you don’t risk losing valuable business opportunities.

Our data building services can make the difference between the success and failure of your lead generation and customer care activities. Whether you want to reduce customer attrition, maximise revenue per customer through product launches, cross-sell and up-sell or laser target new markets, accurate data will maximise the effectiveness of your efforts.

What our happy customers have to say


How does GSA's bespoke data building process differ from typical data providers?

Unlike most data brokers who often resell a fixed pool of data, GSA usually constructs bespoke B2B databases tailored specifically to each client’s unique needs. Our approach combines desk research, advanced AI tools, and platforms such as LinkedIn Sales Navigator, and direct telemarketing to identify and engage the right decision-makers within target organisations. This customisation ensures that the data you receive is not only accurate but uniquely aligned with your specific business objectives.

Whilst not every B2B data build needs a call to a target organisation, many data requirements are for hard to reach decision-makers that are not typically found on most data broker lists. At GSA, we integrate bespoke data building with telemarketing to maximise the effectiveness of your campaigns. This allows us to refine the accuracy of your B2B database to enable you to generate qualified sales leads. We also offer options to screen data using email verification tools and check compliance with the CTPS opt-out register, providing a comprehensive solution that enhances both the reach and responsiveness of your B2B marketing efforts.
Creating a custom-built B2B database with GSA significantly enhances your marketing and sales initiatives by improving targeting accuracy, boosting conversion rates. This tailored approach not only streamlines business development activities but also reduces wastage, making marketing teams far more productive and campaigns more cost-effective. Whilst no B2B data set will ever be perfect, since data is a moving target, a bespoke database facilitates smoother and more successful business development.

Yes, the data provided by GSA is compliant with GDPR regulations. We use ‘legitimate interest’ as a valid lawful basis for processing personal data, ensuring that our data collection methods meet legal standards. While we can perform a legitimate interest impact assessment (LIA) for clients, using our form, we strongly recommend that they conduct their own LIA prior to launching marketing campaigns and seek appropriate legal advice to ensure full compliance.
