What’s Included in a Typical B2B List? Key Data Explained

What’s included in a typical B2B list is one of the most common questions we hear from SME decision-makers — and for good reason. If you’ve ever paid for a marketing list only to find it missing key contact details, irrelevant companies, or patchy information, you’re not alone.

Whether you’re running email campaigns, picking up the phone, or posting mailers, the structure and contents of your data list directly impact your results. But too often, businesses are left guessing about what they’re actually buying — or worse, they’re distracted by volume over value.

This article breaks down the typical structure of a UK B2B data list: what you should expect, what you should avoid, and how different fields power different types of outreach. We’ll also share how Results Driven Marketing builds data lists that are campaign-ready — accurate, compliant, and tailored to your goals.

    Why It Matters to Know What You’re Getting

    Understanding exactly what’s included in a typical B2B list isn’t just a technical detail — it’s the difference between a successful campaign and wasted budget.

    We hear from UK SMEs every week who’ve purchased lists expecting ready-to-use data, only to find incomplete records, irrelevant companies, or lists padded with generic contacts. Without clear expectations, it’s easy to end up with data that’s more trouble than it’s worth.

    Here’s why it matters:

    • Avoid campaign failure – Poor-quality or missing fields can derail email, phone, or direct mail outreach

    • Maximise ROI – Accurate, well-structured data leads to higher response rates and lower cost per lead

    • Save time on admin – Proper formatting means less time cleaning and fixing files before use

    • Support CRM and automation tools – Clean, structured fields integrate more easily into your systems

    Bottom line: if you don’t know what to expect, it’s harder to measure value — or challenge a poor supplier.

    Core Fields in a Standard B2B List

    While every provider’s format may vary slightly, there are some standard fields that should be included in any quality B2B list. These are the data points that allow you to segment, personalise, and run compliant campaigns.

    Company-Level Data

    This is the foundational information that tells you who the business is:

    • Company Name

    • Address (including postcode, town/city, and county)

    • Industry/Sector (often based on SIC codes)

    • Company Size (employee count or turnover bracket)

    • Trading Status

    • Age of Business

    Contact-Level Data

    These fields let you reach real people, not just businesses:

    • Contact Name

    • Job Title

    • Phone Number (direct or main line)

    • Email Address

    • Department (e.g. Sales, Marketing, HR)

    Other Fields That Add Value

    • Website URL

    • LinkedIn company profile

    • Generic email type (e.g. info@, sales@)

    • Geographic tags (e.g. “North West”, “London”)

    • Decision-maker flag

    The presence, quality, and relevance of these fields can make or break a campaign — so always ask for clarity upfront.

    What You Won’t (and Shouldn’t) Get

    A good B2B list gives you what you need for effective marketing — but it won’t (and legally shouldn’t) include everything.

    Here’s what typically isn’t included — and why:

    • Home or Mobile Numbers – Considered personal data under UK privacy laws and not suitable for B2B

    • Consumer Data – These aren’t business contacts and don’t belong in a professional outreach list

    • Sensitive Personal Info – Fields like age, ethnicity, or marital status are irrelevant and carry GDPR risks

    • Overly Personalised Details – Hobbies, responsibilities, or social links are often inaccurate and rarely helpful

    Stick to clean, structured business data — it performs better and keeps you compliant.

    Matching List Fields to Your Campaign Goals

    Not all B2B data is equal — and not every campaign needs the same fields. Understanding how different data points align with your marketing approach helps you choose (and use) the right list.

    Email Marketing

    • Job Title is key – Know who you’re writing to and tailor your message

    • Sector targeting – Keep content relevant by industry

    • Location and size filters – Help personalise tone and expectations

    Telemarketing

    • Phone number quality matters – A bloated list means nothing if half the numbers don’t connect

    • Direct vs switchboard – Each has its place depending on strategy

    • Missing contact names? – Still useful if you’ve got the right department and approach

    Direct Mail

    • Proper address formatting – Saves hours when printing or automating

    • Trading filters – Weed out inactive or dissolved businesses

    • Geotargeting – Add regional flair or local offers to boost response

    Aligning your list with your channel boosts your chances of success — and keeps your team efficient.

    Common Pitfalls to Avoid

    Buying B2B data can feel straightforward — until it isn’t. Many businesses make avoidable mistakes that lead to wasted spend, frustrating outcomes, or worse — compliance risks.

    Here’s what to watch out for:

    • Buying on volume, not relevance – Targeted, smaller lists usually outperform bloated files

    • Assuming all data is structured the same – Check field names and formatting

    • Forgetting how you’ll use it – Make sure the format works with your CRM, email tool, or dialler

    • Overvaluing vanity fields – Extras like LinkedIn profiles are nice, but they won’t save a bad list

    A great list is one you can use immediately — without spending hours fixing or reworking it.
