Key points
- Define accounts, contacts and market opportunity as different units
- Reconcile reviewed records against an explicit reference account set
- Use count preview for database scope without calling it market coverage
Estimate niche ICP coverage by keeping an independently defined account set, available database records and a reviewed campaign cohort separate. Each answers a different planning question.
A large matching-contact total can concentrate at a few companies. An independently researched account list can contain firms the database does not cover. Neither result alone establishes the size or value of the full market.
Define the unit before calculating coverage
| View | Unit | Evidence needed |
|---|---|---|
| Market opportunity | A defined commercial opportunity | Market definition and economic assumptions |
| Reference account set | Reviewed organisations under inclusion rules | Independent sources and resolved identity |
| Database contact scope | Available contacts matching supported criteria | Query, source and observation date |
| Account coverage | Reference accounts with an accepted match | Account-level reconciliation |
| Campaign cohort | Records accepted for a particular action | Role, fields, preferences and eligibility review |
Do not label a matching-contact count as TAM or use it as a unique-account denominator. Contacts, organisations and commercial value are different units.
Build a defensible reference set
Define geography, industry, operating conditions and the account unit. A location, legal entity, parent group and brand can represent different units.
Use appropriate directories, registries, public research or your reviewed account inventory. Record source dates, inclusion rules, unknowns and material gaps.
An incomplete directory remains an incomplete reference set. Report coverage of that set rather than claiming coverage of the whole market.
Use preview for database scope
Dievio count preview is free and reports matching-contact counts. It does not provide full contact details, unique-company totals or independently verified market size.
Translate the brief into supported company, role, location and stored size or revenue criteria. Current technology, purchasing intent and approval processes require separate evidence.
Change one criterion at a time when diagnosing scope. Keep essential constraints rather than broadening simply to reach a larger number. The filter guide covers that comparison.
Retrieve and reconcile actual accounts
- Choose a bounded retrieval for the review task.
- Preserve returned contact and company values.
- Resolve identity under the chosen account unit.
- Group contacts by reviewed account.
- Compare matched and unmatched accounts against the reference set.
- Keep ambiguous relationships unresolved.
New retrieval uses applicable credits. Another download of an accepted saved list adds no search-credit charge.
Domains can support reconciliation, but subsidiaries, franchises and multi-brand groups may require research. Do not collapse every contact at one domain into one economic buyer.

Calculate a clearly scoped coverage ratio
Reviewed reference-set coverage = reference accounts with an accepted match ÷ reviewed reference accounts in scope.
Hypothetical example: if 62 of 80 reviewed target accounts have accepted matches, coverage of that reference set is 77.5%. This does not establish full-market coverage, mailbox validity or buying intent.
Report unresolved matches separately. If the denominator is unknown or zero, do not publish a misleading percentage.
Inspect role and channel gaps
An account match can still lack the relevant responsibility or required contact field. Review those gaps against the actual buying task.
Accounts multiplied by assumed contacts per account produces a planning model, not a measured contact total. Label its assumptions and test them where possible.
Mailbox acceptance, phone ownership and campaign eligibility require their own checks. Available fields do not guarantee reachability.
Plan capacity without promising conversion
Use accepted records, operating effort and appropriately scoped historical outcomes for scenarios. Keep forecast assumptions distinct from observed results.
A small niche can support qualitative discovery, while a large count can contain poor-fit records. There is no universal 500-contact minimum or mandatory two contacts per account.
Use the segment-validation guide to decide whether to proceed, research or revise.
Keep the estimate reproducible
Save the reference-set version, query, reconciliation rules and observation dates. Revisit the estimate when the audience, source coverage or intended action changes.
The territory guide connects reviewed coverage to ownership and workload. The useful output is an explainable boundary for the next decision.
