HOW WE WORK: THE BROKER ADVANTAGE
Why an independent data broker gives you better data
Marketing Data Lists (operated by AD Marketing) is a data broker – not a data warehouse. Many larger providers own a single proprietary dataset, which means you are limited to one source, one methodology, and one view of the market.
As an independent broker, Maxine Broadhurst has spent over 30 years identifying and securing relationships with the best specialist data suppliers in the UK – companies that each excel in specific sectors and use rigorous, telephone-verified and electronically researched collection methods.
This means you benefit from multiple high-quality sources, independently selected for accuracy and compliance, at the most competitive pricing available. You are not buying from a platform — you are buying from someone who knows every supplier in the market and selects the best one for your brief.

You are not buying from a platform — you are buying from someone who knows every supplier in the market and selects the best one for your brief.
WHAT THIS MEANS FOR YOU
Access to the best
suppliers – not just one

Because we are independent, we select the supplier whose data is most accurate for your specific sector, geography, and campaign type.
You always get the best available data – not simply the data one company happens to own.
WHY OUR DATA OUTPERFORMS
Verified data vs scraped
data – a critical difference

Many providers scrape contacts from public sources with no telephone verification – which leads to high bounce rates and poor deliverability.
Our suppliers use direct verification calls and electronic cross-referencing, which is why clients report bounce rates well below the industry average.
HOW OUR DATA IS BUILT: COMPLIANCE METHODOLOGY
How our data is built – and why
compliance is guaranteed
Every record supplied by AD Marketing has been compiled through a rigorous, multi-stage research
and verification process carried out by our specialist suppliers.
Here is exactly how it works:

Telephone Research – Direct Verification
Our data suppliers conduct live telephone-based research to collect and verify accurate business and contact information directly at source.
This involves direct calls to verify:
- Company names and trading details
- Current job roles and personnel
- Live telephone numbers and email addresses

Electronic Research – Digital Source Verification
Electronic Research – Digital Source Verification Data is additionally sourced and cross-referenced through structured online research including:
This involves digital cross-referencing of:
- Company websites and published contact pages
- LinkedIn profiles and professional directories
- Companies House filings, Royal Mail PAF, and official government and sector registers
All electronically sourced records are checked for currency and relevance before being added to the database.

Email Collection & Article 14 GDPR Compliance
Whenever an email address is collected, a Personal Information Processing Notice is sent to that individual in line with Article 14 of UK GDPR.
This notice explains:
- How their data will be used
- The legal basis for processing (Legitimate Interests)
- The individual’s rights including the right to object or opt out at any time
All electronically sourced records are checked for currency and relevance before being added to the database.

Ongoing Transparency & Opt-Out Management
All marketing communications include a clear, functioning unsubscribe link – ensuring recipients can opt out at any time.
If any individual questions how their data was obtained, a dedicated compliance team responds promptly with full source details and a complete GDPR and PECR compliance explanation.
PROBLEM SECTION
Does this sound familiar?
PAIN POINT 1
Campaigns reaching the wrong people
You are investing in outreach but missing decision-makers. Generic or unverified lists mean wasted budget and low response – because the data was never verified at source.
PAIN POINT 2
Uncertainty about GDPR and PECR compliance
Compliance concerns hold marketing teams back. You need data that has been sourced, verified, and made compliant at the point of collection – with Article 14 notices issued and full documentation provided.
PAIN POINT 3
Pipeline stalled – new leads needed
Referrals and inbound are not enough. You need a reliable route to verified UK B2B contacts across the sectors that matter, built to your brief by someone who knows the data market.
PAIN POINT 4
High bounce rates from scraped data
Many providers scrape contacts with no telephone verification – records go stale and bounce rates climb. Telephone-verified data consistently outperforms scraped data on deliverability and open rates.

SOLUTION
Accurate UK B2B data – precisely
targeted, fully compliant.
Marketing Data Lists (operated by AD Marketing) has supplied UK B2B data since 1993. As an independent broker, we source exclusively from vetted specialist suppliers who use telephone research and electronic verification to build records from the ground up – which is why clients consistently report bounce rates below industry average and open rates of 15–30% on cold outreach. Every list is built to your brief, filtered by sector, job title, geography, and company size. All data is UK GDPR and PECR compliant, with Article 14 notices issued at the point of email collection and TPS screening applied to telephone records. Delivered in CSV, Excel, or CRM-ready format within 24 hours.
