Why Quality Prospect Data Matters to Your Marketing

Prospect data has a direct impact on marketing performance. Better data means stronger engagement, more leads, and improved conversion rates.

But not all data is created equal.

Some marketing teams continue using poor-quality lists for years without realising that better options exist. This leads to lost opportunities and, in some cases, major revenue losses.

The Problem with Low-Grade Data

Cheap data lists often come padded with:

• Irrelevant contacts

• Businesses that no longer trade

• Out-of-date details

Sending campaigns to these lists doesn’t just waste money — it risks damaging your brand. Contacting someone who passed away, or a company that closed years ago, does more harm than good.

How to Spot a Poor Data Supplier

Look beyond the price or company age. Being established doesn’t guarantee quality. Ask the right questions:

• Are they members of the Direct Marketing Association or trade bodies like the Glass and Glazing Federation (GGF)?

• How often do they update their data?

• What happens when they can’t reach a company — is the record still listed?

• Do they offer real-time data, or are you buying from a static file?

Web-based systems can be misleading. Uploading a spreadsheet doesn’t make it live data. Always check how current the information really is.

How Insight Data is Different

Insight Data has invested over £250,000 in research in the past year alone. Our database is verified and maintained using seven separate processes:

Real-time feeds from credit reference agencies

Over 20,000 monthly calls from a dedicated research team

Continuous updates across all records

This results in cleaner, more accurate data — and marketing performance up to five times better than outdated lists.

Old Data Is a False Economy

Outdated lists might seem cost-effective on paper, but they rarely deliver results. You wouldn’t run a campaign using obsolete product prices — so why run one on obsolete contact data?

As the saying goes: “You can put lipstick on a pig, but it’s still a pig.”

Choose data that performs.
