About this audience

No single county or borough dominates: City of London is largest at 31 percent, Westminster follows at 19 percent, then Camden at 10 percent. By job level, Senior staff holds 57 percent of contacts (1,755), well ahead of Owner at 31 percent. Senior staff is over-represented: 57 percent here against 14 percent across the database. The spread is similar by industry: Information and communication is largest at 28 percent, Finance and insurance follows at 20 percent, then Professional, scientific and technical at 17 percent. Information and communication is over-represented: 28 percent here against 12 percent across the database. The three largest are City of London, Westminster and Camden, together 60 percent of contacts. A company can hold several SIC codes, so industry shares overlap and can add to more than 100 percent.

1,370 of the contacts are emailable, meaning a named email scoring 70 or more at a corporate subscriber. 2,020 (65 percent) have a telephone number held, below the database figure of 72 percent. Every telephone number is screened against the TPS and CTPS each night through a licensed screening service, and carries its status and the date of that screen. We treat a screen as valid for 28 days, our own rule rather than the ICO's. Screen the numbers you are supplied yourself before calling, and again every 28 days.

This count combines two filters. The job role filter maps written titles to one role through the Emailmovers title dictionary, so variants of a title count together. The region filter comes from the ONS Postcode Directory. It covers named business emails at active UK companies. Individual subscribers, meaning sole traders and ordinary partnerships, are excluded by default, which leaves out 5 contacts here. Emailmovers relies on legitimate interests under UK GDPR Article 6(1)(f) for named business contacts.

How we count explains title matching, places and rounding. The trust page lists sources, sub-processors and the legal basis.
