1. Results Driven Marketing – Best Overall for Targeted UK B2B Email Lists
Best for: Businesses that want a bespoke UK B2B email database built around a clearly defined target market.
Results Driven Marketing, also known as RD Marketing, is a specialist UK B2B data supplier providing targeted email, telephone and postal marketing databases.
Its database covers more than 1.5 million actively trading UK businesses across 2,200+ industries, with targeting available using criteria including:
– Industry
– Location
– Employee numbers
– Turnover
– Company type
– Job role
– Seniority
– Branch status
Results Driven Marketing currently guarantees at least 95% accuracy on supplied email addresses, 95% on telephone numbers and contact names, and 98% on postal addresses.
Rather than requiring customers to subscribe to a platform and search for prospects themselves, Results Driven Marketing can build a database around the customer’s individual targeting requirements.
For example, a business could request:
– Managing directors of UK manufacturing companies
– Finance directors within companies employing more than 50 people
– Marketing managers at recruitment companies
– Construction companies in selected UK regions
– Senior contacts at care homes
– Businesses within a defined turnover range
– Companies within selected postcodes
– Decision-makers within a particular industry
– Customers can establish how many relevant records are available before deciding whether to purchase.

– Sector-specific campaigns
– Regional campaigns
Businesses requiring extensive international coverage, intent data, browser extensions or enterprise-level CRM functionality may prefer a sales intelligence platform such as Cognism, Apollo or ZoomInfo.

2. Cognism – Best for UK and European Sales Intelligence
Cognism is a sales intelligence platform with a strong focus on UK and European prospecting.
Rather than operating primarily as a traditional list supplier, Cognism gives sales teams ongoing access to a searchable database containing company and contact information.
Users can identify prospects, access business email addresses and telephone numbers, enrich existing data and integrate contact information into wider sales workflows.
Cognism is particularly well known for its Diamond Data, where selected mobile telephone numbers are phone verified.
Why consider Cognism?
- Strong UK and European coverage
- Business email data
- Phone-verified mobile numbers
- Sales intelligence functionality
- Browser extension
- Data enrichment
- CRM integrations
- Suitable for ongoing sales prospecting
Who is Cognism best suited to?
Cognism is particularly relevant to established sales teams that prospect continuously across the UK and Europe.
It may be more appropriate than a traditional list supplier where multiple salespeople need frequent access to prospect data and additional sales intelligence tools.
3. Market Location – Best for Human-Verified UK Business Data
Market Location is one of the longest-established B2B data suppliers in the UK.
Its service focuses heavily on UK business information and combines database technology with human verification.
Market Location provides email data, telephone data, postal records, data enrichment and managed marketing services.
The company places particular emphasis on identifying genuine actively trading UK businesses and validating business information through ongoing research and telephone verification.
Why consider Market Location?
- Established UK B2B data provider
- Strong focus on UK businesses
- Human data verification
- Email, telephone and postal data
- Detailed targeting
- Data cleansing
- Data enhancement
- Managed marketing services
Who is Market Location best suited to?
Market Location is particularly relevant for organisations that value human verification and detailed UK business information.
Its broader range of services may also appeal to companies running large multichannel B2B marketing programmes.
4. Apollo – Best for Self-Service Prospecting and Outreach
Apollo combines a large international B2B contact database with prospecting and outbound sales tools.
Users can search for businesses and contacts, apply filters, export prospect information and add contacts to outbound email sequences.
This makes Apollo quite different from a traditional B2B email list supplier.
Rather than giving the supplier a targeting brief and receiving a finished database, customers generally build and manage their own audiences.
Why consider Apollo?
- Large international database
- UK business contact data
- Self-service prospecting
- Detailed search filters
- Email sequencing
- CRM integrations
- Data enrichment
- Ongoing access to prospect data
Who is Apollo best suited to?
Apollo is particularly useful for organisations where salespeople want to create and manage their own prospect lists on an ongoing basis.
Businesses wanting both contact data and outbound email tools within one platform may find this approach particularly useful.
5. Lusha – Best for Contact Discovery and Enrichment
Lusha provides business contact and company data through its prospecting platform, browser extension, API and integrations.
It is designed primarily for salespeople who want to identify or enrich individual contacts while prospecting.
Users can access business email addresses, telephone information and company data and add prospect information into their sales systems.
Why consider Lusha?
- Large international contact database
- Business email data
- Telephone contact information
- Browser extension
- CRM enrichment
- API access
- Company intelligence
- Self-service prospecting
Who is Lusha best suited to?
Lusha is particularly relevant for sales teams that regularly research individual decision-makers and want to access additional contact information during the prospecting process.
It is less suited to companies simply looking for a finished UK B2B database prepared to a specific brief.
6. Kaspr – Best for LinkedIn-Based Prospecting
Kaspr is a prospecting platform designed heavily around LinkedIn and LinkedIn Sales Navigator.
Its browser extension allows users to access contact information while viewing individual prospect profiles.
This can include business email addresses, telephone numbers and company information.
Why consider Kaspr?
- Strong European focus
- LinkedIn integration
- Sales Navigator compatibility
- Business email addresses
- Telephone numbers
- Browser extension
- CRM integrations
- Useful for individual prospect research
Who is Kaspr best suited to?
Kaspr is particularly appropriate for sales development representatives and business development teams that already use LinkedIn extensively for prospecting.
It is fundamentally different from a bespoke email list supplier because the sales team normally identifies each prospect itself.
7. Corpdata – Best Traditional UK Data Alternative
Corpdata is an established UK B2B marketing data supplier that has operated within the business information sector for more than 30 years.
Its services include targeted email lists, telemarketing lists, postal mailing lists and database cleansing.
Its model therefore has more in common with Results Driven Marketing and Market Location than with self-service platforms such as Apollo, Lusha or Kaspr.
Why consider Corpdata?
- Long-established UK B2B supplier
- UK-focused business data
- B2B email lists
- Telemarketing lists
- Postal mailing lists
- Data cleansing
- Data enhancement
- Managed data service
Who is Corpdata best suited to?
Corpdata is likely to suit companies that prefer working with a traditional UK data supplier rather than purchasing access to a large international sales intelligence platform.
8. ZoomInfo – Best for Enterprise Sales Intelligence
ZoomInfo is one of the world’s largest sales intelligence platforms.
Its technology extends far beyond business email addresses and includes company intelligence, contact information, prospecting tools, data enrichment, intent data and other go-to-market functionality.
This means ZoomInfo serves a very different type of requirement from a specialist UK B2B email list provider.
Why consider ZoomInfo?
- Large international database
- Extensive company intelligence
- Contact information
- Intent data
- Sales prospecting functionality
- Data enrichment
- CRM integrations
- Enterprise-focused functionality
Who is ZoomInfo best suited to?

Frequently Asked Questions
For businesses specifically looking to purchase a targeted UK B2B email database, Results Driven Marketing is our top choice.
Its combination of UK-focused coverage, more than 2,200 industry classifications, detailed company and decision-maker targeting, bespoke database building and a 95%+ email accuracy guarantee makes it particularly well suited to UK outbound marketing campaigns.
Other providers may be more appropriate for different requirements.
Cognism, Apollo, Lusha, Kaspr and ZoomInfo, for example, are primarily sales intelligence platforms and may suit businesses that require ongoing access to international prospecting software rather than a finished UK marketing list.
UK B2B email lists can be purchased from specialist suppliers including Results Driven Marketing, Market Location and Corpdata.
Businesses can also use sales intelligence platforms such as Cognism and Apollo to identify and export their own prospects.
Accuracy levels vary significantly between suppliers.
Before purchasing data, ask whether the provider offers an accuracy guarantee and what happens if records are found to be incorrect.
Results Driven Marketing currently guarantees at least 95% accuracy on supplied email addresses.
Yes.
Specialist B2B data providers can usually segment businesses according to industry or sector.
Results Driven Marketing provides access to more than 2,200 industry classifications alongside targeting by geography, company size, turnover, job role and seniority.
Yes, subject to data availability.
B2B databases can often be targeted around roles including:
- Managing directors
- Finance directors
- Marketing directors
- Marketing managers
- HR directors
- HR managers
- Operations directors
- Sales directors
- Procurement contacts
It can be, but purchasing a database does not remove the responsibility to comply with UK GDPR and PECR.
The rules depend on the type of organisation and individual being contacted and how the data is being processed.
Businesses should review the ICO’s current direct marketing guidance before launching campaigns.
If you need a database for a defined UK campaign, purchasing a bespoke B2B email list may be the simpler option.
If your sales team prospects every day and frequently changes its target audience, ongoing access to a platform such as Cognism, Apollo, Lusha or Kaspr may be more appropriate.
Depending on the supplier and available records, a B2B database may include:
- Company name
- Postal address
- Contact name
- Job title
- Business email address
- Telephone number
- Industry
- Employee numbers
- Turnover
- Website
How We Compared the Best B2B Email List Providers
There is no value in comparing providers purely by the total number of contacts they claim to hold.
A database containing hundreds of millions of international records may be less useful than a much smaller database if your target market consists entirely of UK businesses within a specific sector.
For this comparison, the most important factors include:
- UK market coverage
- Ability to target specific industries
- Decision-maker targeting
- Email accuracy
- Data verification
- Ease of obtaining a targeted audience
- Flexibility
- Support
- Pricing model
- Suitability for UK B2B campaigns
We have also considered whether each provider is primarily a traditional data supplier or a sales intelligence platform, because these are two very different ways of purchasing and using B2B data.
B2B Email List Supplier vs Sales Intelligence Platform
One of the most important decisions is whether you actually need a B2B email list supplier or a sales intelligence platform.
Both provide access to prospect data, but the way they work is very different.
B2B email list supplier
With a traditional list supplier, you normally describe the type of customer you want to reach.
For example:
UK engineering companies employing between 20 and 250 people, targeting managing directors and operations directors.
The supplier identifies how many matching businesses and contacts are available and then supplies the finished database.
This approach can work well when you:
- Already know your target market
- Need data for a specific campaign
- Don’t want another software subscription
- Want help selecting the correct audience
- Need detailed UK segmentation
- Want to know the available volume before buying
- Prefer the supplier to build the audience for you
Sales intelligence platform
Platforms such as Cognism, Apollo, Lusha, Kaspr and ZoomInfo provide direct access to a database.
Your sales team searches, filters and selects individual prospects itself.
This model may be preferable when:
- Prospecting happens every day
- Multiple salespeople need access
- Your target market changes frequently
- International data is important
- CRM integration matters
- LinkedIn forms part of the sales process
- You need intent signals or additional sales intelligence
Neither model is inherently better.
However, for companies simply wanting a targeted UK B2B email database, a specialist supplier can often provide a more straightforward route to the finished data.
What Should You Look for in a B2B Email List Provider?
Choosing a B2B data supplier purely on price can be a mistake.
The quality and relevance of the data will normally have a much greater impact on campaign performance.
Here are some of the main things worth checking.
1. UK coverage
If your customers are based in the UK, ask suppliers specifically about the strength of their UK database.
A provider may advertise hundreds of millions of international contacts while holding much less detailed information for your particular UK audience.
2. Email accuracy
Ask whether the supplier provides an accuracy guarantee.
Business data changes constantly as employees change roles, businesses relocate, companies close and email addresses change.
A reputable supplier should be able to explain how its information is maintained and what happens if incorrect records are supplied.
Results Driven Marketing currently guarantees at least 95% accuracy on supplied email data.
3. Targeting options
The size of the database is only part of the story.
Being able to identify the correct businesses and contacts is often much more valuable.
Useful targeting criteria can include:
- Industry
- Geography
- Employee numbers
- Turnover
- Job role
- Seniority
- Company type
- Branch status
- Business size
4. Decision-maker information
Company-level information alone may not be enough.
If your campaign is aimed at finance directors, marketing managers or managing directors, check whether the supplier can identify relevant named decision-makers.
5. Data source and maintenance
Ask how frequently the database is updated and how the supplier identifies businesses that have closed, moved or changed personnel.
6. Pricing model
Traditional suppliers may charge according to the amount of data purchased.
Sales intelligence platforms are more likely to charge monthly or annual subscriptions.
Consider the total cost based on how often you genuinely need new data.
7. Support
If you aren’t completely sure which sectors or job roles to target, having access to an experienced data specialist can make a significant difference.
Self-service software gives users more control, but it also places more responsibility for audience selection on your own team.
Is It Legal to Buy B2B Email Lists in the UK?
Buying B2B marketing data is not automatically prohibited in the UK, but businesses still need to understand their responsibilities under UK data protection and electronic marketing rules.
Two important areas of regulation are:
- UK GDPR
- Privacy and Electronic Communications Regulations, commonly known as PECR
The rules differ depending on who you are contacting.
Corporate subscribers, such as limited companies, are treated differently under PECR from individuals, sole traders and some partnerships.
Where personal data is being processed, UK GDPR may also apply.
Businesses using purchased B2B email data should therefore consider areas including:
- Lawful basis for processing
- Transparency
- Data sourcing
- Relevance of the marketing
- Rights to object
- Suppression of opt-outs
- Identifying the sender
- Providing a straightforward unsubscribe option
Buying data from a supplier does not automatically make every subsequent use of that data compliant.
Businesses should understand the ICO’s guidance and assess how the rules apply to their individual campaign.
Why UK-Specific B2B Data Matters
Many international sales intelligence platforms advertise enormous databases.
That can sound impressive, but database size is only useful if the records match your actual target market.
A company selling commercial services exclusively within the UK may gain little value from access to hundreds of millions of overseas contacts.
UK-specific targeting can make it easier to segment businesses by:
- UK region
- County
- Town
- Postcode
- Industry
- Company size
- Employee numbers
- Turnover
- Job role
For businesses running targeted UK outbound campaigns, the relevance of the database is usually more important than its headline size.
Which B2B Email List Provider Is Best for UK Businesses?
The answer depends on the type of data service you need.
For businesses wanting a bespoke UK B2B email database built around a specific target market, our top choice is Results Driven Marketing.
Its combination of UK-focused coverage, detailed targeting, decision-maker information, bespoke database building and a 95%+ email accuracy guarantee makes it particularly well suited to targeted UK marketing campaigns.
Market Location and Corpdata are also established UK data specialists worth considering.
For businesses looking for continuous access to a UK and European sales intelligence platform, Cognism provides a strong alternative.
Companies wanting a self-service prospecting platform with outbound sales functionality may prefer Apollo, while Kaspr and Lusha can be particularly useful for individual prospect discovery.

The important distinction is whether you want your team to search for prospects itself or whether you want a specialist supplier to build the targeted audience for you.
