01
Buyer function known
The likely department or role is grounded in how a purchase decision would be made, but no individual has been identified.
D2 GROUP / RESEARCH QUALITY GUIDE
B2B Buyer & Contact Verification: what counts as a usable contact?
A relevant company is not automatically a contact-ready lead. This guide distinguishes a useful buyer function, a named contact, a verified direct business email and a documented contact gap.

Direct answer
When is a researched B2B buyer contact actually verified?
A B2B contact is review-ready only to the standard agreed in the research brief: the person's current role or buyer function must be grounded in an attributable source, the contact route must be clearly identified, and any required direct email must have appropriate verification. A job title, guessed email pattern or general inbox is not equivalent to a confirmed direct contact.
Decision-maker research identifies appropriate buying functions. This guide answers a different handoff question: what level of evidence is present for each contact field, and when should a record be held?
RESEARCH / FIELD SCOPE
Five contact states worth distinguishing
Do not collapse these states into a single 'contact found' checkbox. Handoff acceptance depends on the approved scope and the client's outreach realities.
02
Named person with sourced role
A business source identifies an individual and their role; current employment and responsibility may still need checking.
03
Business contact route available
A published department, switchboard or company inbox offers a contact route, but it is not a direct personal email.
04
Direct business email verified
An attributed business email is recorded with an appropriate verification method and source/date, subject to lawful and suitable use.
05
Gap, stale or contradictory contact
The role, affiliation or address is missing, outdated, unverified or conflicting. It is held or flagged—not silently upgraded.
Frequently asked questions
Frequently asked questions
Does a LinkedIn name prove the person can approve a purchase?
No. The current job and relevant buying authority need to be considered separately, with dated evidence where obtainable.
Is a generic company email a verified decision-maker contact?
No. A general mailbox can be a business contact route, but it is not the named buyer's direct address.
Why hold an otherwise ICP-fit account?
If the agreed handoff requires a verified direct contact, a missing or disputed email is a disclosed GAP rather than an accepted contact-complete lead.
SCOPE / ACCEPTANCE
Define contact acceptance before ordering research
Specify required functions, named buyers, direct emails, geography, existing CRM exclusions and how unresolved gaps will be reviewed. D2 can then scope a realistic research handoff.

EVIDENCE / INFERENCE / GAP
Contact field vs permissible conclusion
These labels communicate evidence strength. They are not a claim that every sector, country or brief uses identical contact requirements.
| What the researcher has | What can be stated | What must not be stated |
|---|---|---|
| Department or role only | Relevant buying function identified | Named decision maker verified |
| Named person on dated source | Person–role connection observed as of the cited source | Current role or reachable email guaranteed |
| [email protected] (fictional) | Illustrative general company inbox format | Verified personal email of the specific buyer |
| Unverified generated email pattern | Unconfirmed hypothesis; do not use as verified contact | Direct email verified or safe to send |
Contact research and QA workflow
- 01
Identify the buying function
Start from the seller's product, commercial decision, technical gate, procurement route and client's target roles—not a generic seniority title.
- 02
Record source and affiliation
Capture a business-appropriate source, the exact role wording, company affiliation and date last checked. Resolve name changes and possible departures.
- 03
Classify the route, not just the string
Distinguish direct business email, department mailbox, switchboard, profile URL and inferred/unverified address. Avoid scraped personal or sensitive data.
- 04
Check conflicts and lawful usage
Review source freshness, organizational mismatch, exclusions and applicable communication requirements. Public visibility is not blanket permission to email.
- 05
Set acceptance or GAP state
Mark accepted, held for contact verification or excluded against the brief; provide the missing field and next validation step.

- Target company
- Hypothetical B2B manufacturing account with confirmed ICP fit
- Buying function
- Plant operations and engineering; source needed for current decision route
- Named person
- Not found in verified business sources
- No verified DIRECT business email; do not generate a guessed address
- Evidence
- No source URL or last-check date recorded yet
- QA disposition
- Hold — contact gap. Retain the company research only if the brief allows a non-contact-complete record.
Review criteria
Contact handoff checklist
- The approved ICP and required buyer function are explicit
- Role, affiliation and contact route have sources and verification dates
- Named buyer is not confused with the department alone
- Direct email, general mailbox and unverified pattern are separate fields
- Duplicate CRM / suppression / privacy constraints are respected
- Missing fields and whether a lead is outreach-eligible are recorded independently of research acceptance
