Who is in this audience?

About this audience
No single county or borough dominates: Westminster is largest at 25 percent, City of London follows at 21 percent, then Camden at 12 percent. The spread is similar by company size: the 10,000 or more employee band is largest at 20 percent, the 1,500 to 4,999 employee band follows at 14 percent, then the 100 to 199 employee band at 10 percent. The 10,000 or more employee band is over-represented: 20 percent here against 8.5 percent across the database. By company type, Private limited company holds 75 percent of contacts (79,270), well ahead of Public limited company at 20 percent. Public limited company is over-represented: 20 percent here against 7.4 percent across the database. The three largest are Westminster, City of London and Camden, together 58 percent of contacts.
48,335 of the contacts are emailable, meaning a named email scoring 70 or more at a corporate subscriber. 71,870 (68 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 industry filter uses the SIC 2007 section (section M), and a company counts when any of its codes falls in the section. 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. 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.
