What Questions to Ask a B2B Data Supplier Before You Buy

What questions to ask a B2B data supplier before you buy can make the difference between a high-performing campaign and wasted budget. Many UK SMEs invest in data only to discover that their lists lack key fields, are outdated, or come with restrictive licence terms—often when it’s too late.

If you’re buying B2B data to power your email outreach, telephone campaigns, or direct mail, you need more than just volume—you need clarity, compliance, and usability. That all starts with asking the right questions upfront.

In this post, we’ll walk you through the essential questions every business owner, sales director, or marketer should ask a B2B data supplier before purchase. You’ll learn how to verify data quality, assess licence and usage terms, understand support options, and make confident decisions. Armed with this guide, you’ll avoid surprises and give your campaigns the best chance of success.

Why Asking the Right Questions Matters

What questions to ask a B2B data supplier isn’t just about ticking boxes—it’s about protecting your investment and ensuring you get data that delivers results.

• Avoid nasty surprises – Too many businesses receive data missing key fields, full of irrelevant contacts, or bound by hidden licence restrictions.

• Improve ROI – The right data enhances targeting, response rates, and campaign efficiency.

• Stay compliant – Asking about CTPS, PECR, and GDPR keeps your efforts legally sound.

• Hold suppliers accountable – A confident supplier will welcome your questions—they know their data is reliable.

Whether you’re planning a cold email campaign, building a call list, or refining your targeting by industry or role, asking the right questions can determine your success. Let’s begin with data quality.

Core Questions About Data Quality and Accuracy

How Recent Is Your Data?

• When was the list last updated and how frequently is it refreshed?

• Do they refresh monthly or at least quarterly?

• Aged data often leads to high bounce rates and wasted outreach.

What Fields Do You Provide?

• Are you getting company name, contact name, job title, email, phone, industry, turnover?

• Can you request specific segmentation by job role, region, or sector?

• More useful fields allow for better targeting.

How Do You Ensure Contact Accuracy?

• How is the data sourced—through surveys, official filings, directories, or partners?

• Do they report accuracy benchmarks (e.g., 95% email deliverability)?

• Do they offer replacements if data doesn’t meet accuracy guarantees?

If a supplier can’t answer clearly, it’s a red flag. Next, let’s explore licence and usage terms.

Licence and Usage: Legal & Operational Considerations

What Is the Licence Duration and Scope?

• Is this a single-use licence, time-limited, or perpetual?

• Are there restrictions on how long you can keep or reuse the data?

• Are certain channels (email, phone, post) restricted?

Can I Share the Data Across My Team or Partners?

• Is internal sharing allowed across your team?

• Can you give the list to an agency or telesales partner?

• Beware of suppliers who restrict usage or charge per user.

What Happens to Opt‑Outs or Complaints?

• Do they support suppression lists, do-not-contact management, and handle complaints?

• Do they help ensure compliance with CTPS and PECR?

• What is the process for managing unsubscribes or complaints?

Clear licence terms are essential—if they’re vague or confusing, it can limit your campaign flexibility or risk legal non-compliance. Up next: integration and post-purchase support.

Integration and Campaign Support

Do You Provide File Formats Optimised for CRM or Marketing Tools?

• Can they deliver lists in formats like CSV or Excel compatible with your systems?

• Are fields clearly labelled and mapped for easy import?

• Ask for a sample file layout if you’re unsure.

What Support Do You Offer After Purchase?

• Is there someone you can contact if something is wrong with the list?

• How responsive is their support team after you’ve bought?

• Do they provide guidance on managing suppression or segmentation?

Do You Offer Any Campaign Advice?

• While not a marketing agency, can they suggest data segmentation or prioritisation strategies?

• Practical recommendations from data experts can make a big difference.

A reliable supplier remains available even after the sale to help integrate and optimise the data. Next we’ll cover pricing and guarantees.

Pricing, Guarantees, and Transparency

How Is Pricing Structured?

• Is pricing per 1,000 records or based on filters like role or sector?

• Are discounts available for bulk orders?

• Are there hidden costs (e.g., CTPS screening or special formats)?

Do You Offer Data Guarantees or Replacements?

• If deliverability falls short, will the data be replaced or refunded?

• Do they have SLAs for resolving issues?

• Do they track accuracy rates and service performance?

Are There Clear Terms and Conditions?

• The licence and pricing terms should be easy to understand—no hidden clauses.

• Look for policies around refunds, retention, and compliance practice.

• Clear, jargon-free terms are a must—no grey areas allowed.

If a supplier avoids giving straightforward answers, it’s a strong signal to look elsewhere.
