What is a B2B database?

A reliable database is essential to structure effective sales prospecting, aligning your targeting, your message and the channels you use.

The key information in a B2B database

To be usable, a professional database can't just be a list of names bought at random. It must compile structured information that lets you finely segment your prospects so you can hyper-personalize your approach. It generally contains three main categories of data. Fine segmentation lets you adapt your prospecting script and significantly increase your response rates.

Firmographic data

This is the target company's identity card. It includes the company name, industry (often defined by its NAF/APE code in France), company size (number of employees), annual revenue, and the head office address or SIRET registration number. These elements are crucial to check whether the company matches your ideal customer profile (ICP).

Contact data

Once the company is identified, you need to be able to reach the right person. This section includes the target decision-maker's first and last name, their exact job title, their personal business email address and their phone number (ideally a direct line or business mobile rather than the switchboard). Access to the prospect's LinkedIn profile is also a real plus.

Business signals (or intent data)

This is what separates a basic database from a high-performance one. This contextual data includes recent company news (funding round, large-scale hiring, relocation), the web technologies used in-house (for example, whether they use Shopify or WordPress), and past interactions with your brand (website visits, white paper downloads).

Good to know

Around 30% of the data in a B2B database becomes outdated every year. This "data decay" is caused by job changes, mergers and acquisitions, and company closures. Regular updates are therefore just as important as building the database in the first place.

How do you build a high-performing database?

There is no single way to build your prospecting file, but rather several complementary approaches to adapt to your budget, your in-house resources and your urgency. Depending on your resources, it may make sense to outsource your prospecting to speed up building your database.

Acquisition (buying or renting files)

You can go through data brokers or specialized platforms that sell pre-qualified lists based on your criteria. It is a very fast way to launch a campaign immediately. However, it requires great vigilance: you must make sure the data is up to date and that the provider has a good reputation, to avoid massive bounce rates.

Web scraping and enrichment

This is the method favored by B2B growth teams today. Modern tools can extract publicly available data from professional networks such as LinkedIn or from online directories. These raw lists are then "enriched" with specialized software (Dropcontact, Lusha, Kaspr) whose algorithms find and verify the matching business email addresses in real time. These practices are often part of an automated prospecting approach that makes it possible to scale the acquisition of qualified contacts quickly.

Inbound marketing (lead generation)

‍

Inbound relies on a qualified lead generation strategy, in which prospects come to you through high-value content. It is the most qualitative and sustainable method over the long term. When you offer high-value content (white papers, webinars, customer case studies, newsletters) on your website, your prospects fill in forms. They voluntarily give you their contact details in exchange for your expertise. The data is then 100% reliable and the prospect is already engaged.

How much does a B2B database cost?

The price of a B2B database varies enormously depending on the acquisition method and the quality of the data. A one-off file purchase from a broker generally costs between €0.15 and €1 per contact, depending on the targeting criteria. Today, the trend is rather towards SaaS subscriptions (enrichment tools and online databases) that charge between €50 and €200 per user per month for a set number of credits (exports of leads and verified emails). The cost of a database should be put into perspective with an overall outsourced prospecting strategy designed to maximize return on investment.

The best tools to manage and enrich your data

To scale up, digital tools are a must. A database doesn't live in a simple Excel file: it must be connected to your sales ecosystem so your teams can make full use of it.

How do you clean a B2B database?

To clean a B2B database, start by removing duplicates using your CRM's deduplication features (often based on the company's domain name). Next, it is crucial to use an email verification tool (such as ZeroBounce) that pings mail servers to make sure addresses are still active. Finally, updating your contacts' current job titles and companies can be automated with tools that regularly sync with LinkedIn profiles.

The golden rules of compliance (GDPR) in B2B

Collecting and using business data is not exempt from the law. While salespeople often see the General Data Protection Regulation (GDPR) as a constraint, it is in fact a great safeguard that encourages higher-quality practices.

‍

In B2B prospecting, the rule differs slightly from B2C. Prior consent (opt-in) is not strictly required to send a prospecting email to a personal business address (e.g. jean.dupont@entreprise.com), provided the message is directly related to the recipient's job. For example, you can legally prospect an HR Director to sell them payroll software.

‍

However, you absolutely must:

• Tell the prospect where you obtained their data if they ask.
• Provide a simple, visible and immediate way to unsubscribe (opt-out link at the bottom of the email).
• Not keep data indefinitely without any interaction (the norm is often 3 years maximum).

Is it legal to buy an email database?

Yes, it is entirely legal to buy or rent a B2B email database in France, provided the provider scrupulously complies with the GDPR. When buying, you must make sure the provider collected the data transparently (public sources or partner opt-in). Once the file is in your hands, the responsibility is yours: you must target professionals for whom your offer is relevant and always include an unsubscribe link in your emails.
