B2B contact data

How B2B contact data works

A B2B contact record has two halves. The person half holds a name, job title, seniority, department, work email, phone number and a public profile URL. The company half holds the employer's name and domain, plus the firmographics that describe it. A title only makes sense next to its company, so most teams store and refresh both halves together.

The data reaches a team through three routes. People publish some of it themselves, on professional profiles, company websites and conference pages. Some comes from the team's own systems, such as sign-up forms, event scans and the CRM. The rest is bought from a B2B data provider, which compiles records from many inputs and sells access by seat, by export or by API call.

Each field does a separate job. Name, title and seniority tell a seller who the person is and whether they buy. The work email and the direct dial say how to reach them. A profile URL ties the record to one identity, which makes later data enrichment more reliable than matching on a name alone.

Privacy law applies to the person half. The ICO says the UK GDPR applies whenever a business contact can be identified, directly or indirectly 1. Holding a contact's name and number counts, and so does an email address that identifies a person 1. Mail sent to a department or a generic inbox, with no named person, falls outside the UK GDPR 1. The European Commission draws the same line for the EU, listing a named company email as personal data and a generic info address as data that is not 2.

Which contact fields go stale first

Contact data ages unevenly. When a person changes jobs, the employer, title, work email and work phone all change on the same day. The US Bureau of Labor Statistics measures how often people change employers 3. In January 2026, 20.6% of US wage and salary workers had been with their current employer for a year or less 3. Median tenure was 4.1 years overall, 6.1 years in management jobs and 2.9 years in service jobs 3.

• Work email. It usually stops working when the person leaves, and the next send to it hard bounces.
• Desk phone and direct dial. The employer usually reassigns or retires the number after a departure.
• Title and seniority. These change on promotion, often with no other signal.
• Name, personal profile URL and mobile number. These follow the person from job to job, so they last longest.

So a list of managers tends to hold up longer than a list of service staff 3. Store a last-checked date on every record, so you can tell an old record from a recently verified one. Re-check the work email right before each campaign with email verification, and treat a rising hard bounce rate on one segment as the first sign of data decay there.

Example of B2B contact data

Take a list of 500 prospects at target accounts, each with only a LinkedIn profile URL 4. The goal is a contact record with title, company, work email and a verification result, and the RichAPI rates make the cost easy to model 4.

Profile enrichment returns the person half of the record, including current title, current company and location, for 1 credit per call 4. For 500 profiles that comes to 500 credits 4. Email finder then looks for a work email at 5 credits per call 4. It is a waterfall endpoint, and a response with success false bills zero credits 4. Suppose it finds 320 addresses 4. Those cost 1,600 credits, and the 180 misses cost nothing 4. Email verifier checks the 320 found addresses at 2 credits each 4. That adds 640 credits 4.

The total is 2,740 credits for 320 reachable contacts, or about 8.6 credits per usable record 4. The honest unit cost divides the spend by usable records instead of list size, since the 180 records without an email cannot be mailed 4.

The finished records are personal data, so the compliance steps sit next to the data steps. The ICO says a business that collects contact details in a business capacity for direct marketing must tell the person and have a lawful basis under the UK GDPR 1. Keep the source and the collection date for each record, so the privacy notice can say where the data came from and when.

B2B contact data vs firmographics

The two cover different halves of the same record. B2B contact data describes a person, the buyer you want to reach. Firmographics describe the company, such as its industry, size and location. Targeting usually starts with firmographics to pick accounts, then moves to contact data to find the people inside them. Contact data carries privacy duties because it names individuals, while company-level facts such as a registration number are not personal data 2.
