The vocabulary of professional contact data

Short definitions of the terms you will meet on ExpressReach and in your sales, recruiting and data-quality work.

Account qualification: Checking a target company before investing sales time: who holds the function you sell to, and whether that contact is current.

Bounce: An email that could not be delivered. Hard bounces (address does not exist) should be removed from a list; soft bounces (full mailbox, temporary error) may be retried.
Buying committee: The group of people involved in a purchasing decision at a company — the function that uses, the one that pays and the one that signs.

Career history: The succession of roles and employers a professional has published about themselves: current position, past positions, location.
Catch-all domain: A mail domain that accepts every address, which makes individual deliverability impossible to confirm. Results from such domains are flagged as unverifiable.

Decision-maker: The person who holds the function your product or offer is addressed to, and who can take or influence the decision.
Deliverability: Whether an email address can actually receive mail, checked through the domain's mail servers without sending a message.
Directory listing: An entry in a published business or telephone directory: the holder as listed, the number, the address of the establishment.
Disposable address: A temporary mailbox created for a one-off sign-up. Flagged by verification so it is not used for follow-up.

Email format: The pattern a company uses for its business addresses (first.last@, f.last@, first@…), derived from published addresses on the domain.
Enrichment: Completing a contact record with additional professional details (company, role, business email, office number) from public and professional sources.

Fair use: The usage limits of the subscription, such as the number of detailed reports per month.

Homonym: Two professionals with the same name. Adding the company or the city is what separates them in a people search.

Line type: Whether a phone number is a landline, a mobile, a VoIP line or a premium-rate number. Useful to know what kind of line you are about to call.

Numbering plan: The structure of a country's phone numbers: country code, prefixes, length and the ranges assigned to each line type.

Public source: Information anyone can read without logging in: company websites, public professional profiles, published directories.

Reverse email lookup: Starting from an email address to find the professional and the company it belongs to, when published sources allow it.
Reverse phone lookup: Starting from a phone number to find the publicly listed holder — usually a business or a directory entry. Unlisted numbers return nothing.
Role address: A generic mailbox such as info@ or sales@. Fine to contact a company, not a person.

Sales intelligence: The practice of collecting and verifying professional information about companies and decision-makers to prioritise and prepare outreach.
Switchboard: The main published line of a company or establishment, from which calls are routed to a function or a person.

Talent sourcing: Identifying and reaching professionals who match an open role before they apply, through the professional profiles they published.

Unlisted number: A phone number whose holder asked not to appear in directories. Such numbers are not returned by the service.

Verification: Confirming that a contact detail is valid and current — a deliverable email address, an active line, a company still active.
