B2B Data for Marketing Agencies: A Smart Way to Add Value

Buy Data Data Services

B2B data for marketing agencies has become more than a nice-to-have — it’s now essential for delivering fast, targeted, and cost-effective campaigns.

Whether you’re running email marketing, telemarketing, or direct mail, solid data is what makes the difference between mediocre results and high-performing outreach. Agencies are expected to generate leads, drive engagement, and do it all quickly — often with tight budgets and even tighter deadlines.

And that’s exactly where the right data partner comes in.

A Faster, Easier Way to Offer Data as a Service

Let’s be honest: most agencies don’t want the hassle of sourcing, cleaning, and filtering data. It’s time-consuming, expensive, and not your core business.

But if you work with a partner who already does all of that for you, you can offer B2B data as a service — without hiring analysts or building complex systems.

Here’s how that can look in practice:

A client wants to test a cold email campaign for accountants — we deliver a list within 24 hours.
Another client is launching a direct mail campaign to vets — we provide clean postal data with contact names.
You’re building a retargeting list for a webinar — we help you filter decision-makers by job title, turnover, and region.

You focus on the campaign strategy. We’ll handle the data behind the scenes.

What Kind of Data Can You Access?

We work with the UK’s largest business data aggregator — combining sources like 118 Information, Companies House, Dun & Bradstreet, and more — to deliver campaign-ready data across thousands of sectors.

For each record, you can access:

Business name and trading address
Telephone numbers (CTPS-checked daily)
Email addresses (where available)
Contact names and job titles
Turnover and staff size
Industry classification (SIC)
Geographical filters

All supplied under a 12-month multi-use licence in Excel or CSV format — ready to drop straight into your CRM or automation tools.

Solving Common Agency Pain Points

Agencies we work with usually come to us with one or more of the following problems:

❌ Their client supplied old, incomplete or non-compliant data
❌ They’re wasting hours manually researching or buying unreliable lists online
❌ Campaign results are poor due to badly targeted data

We solve this by supplying highly targeted lists, matched exactly to the campaign brief. Whether you’re targeting facilities managers in London, HR directors in Scotland, or start-ups with under 10 employees — we’ve got filters to suit.

And if your client needs to prove GDPR compliance, we’ve got the sourcing documentation to support you. Read more on GDPR.

Fast Turnaround and Flexible Support

One of the biggest reasons agencies come back to us? We’re fast.

In most cases, we can turn around a count the same day — and once approved, the data is usually delivered within 24 hours (often faster). You also get:

12-month multi-use licence
Accuracy guarantees (98% postal, 95% email and telephone)
Like-for-like replacements if benchmarks aren’t met
Support from real humans (phone, email or live chat)

Whether you’re delivering a one-off campaign or need a steady stream of data across client accounts, we’re happy to stay in the background — acting as your data team without adding to your payroll.

FAQs: B2B Data for Marketing Agencies

What exactly is B2B data, and how can a marketing agency use it?
B2B data refers to contact information and business details for companies and key decision-makers. Marketing agencies use this data to run targeted campaigns, generate leads, build prospect lists, and support clients with more personalised outreach.

Can I resell the data to my clients?
Yes — as long as your licensing agreement allows for it. At Results Driven Marketing, all datasets come with a 12-month multi-use licence, which gives you and your clients plenty of flexibility.

How do I make sure the data is GDPR-compliant?
We ensure that every dataset we supply meets UK GDPR and PECR standards, including up-to-date CTPS checking for telephone records. For more guidance on legal compliance, visit the ICO’s website.

How accurate is the data?
Our records are pulled from a master file that updates over 700,000 fields per month and are backed by industry-high accuracy guarantees — 98% for postal, 95% for telephone, and 95% for email.

What if my client wants to target a really niche sector?
No problem — our filters let you drill down by sector, geography, turnover, staff size, job title and more. Whether your client sells to dentists, architects or facilities managers, we can build a list that fits the brief.

How quickly can I get a list?
In most cases, we’ll provide a data count the same day — and once approved, the full dataset is usually delivered within 24 hours (often faster).

Can you help us run the campaign as well?
Yes. We offer a managed email marketing service and an email platform called Responder, which is ideal for agencies looking to outsource execution or run campaigns in-house using purchased data.
