About this audience

No single county or borough dominates: Westminster is largest at 24 percent, City of London follows at 19 percent, then Camden at 9.6 percent. The spread is similar by job function: General management is largest at 33 percent, Finance follows at 13 percent, then Unknown at 7.8 percent. General management is over-represented: 33 percent here against 22 percent across the database. By company size the audience is also spread out: the 1,500 to 4,999 employee band is largest at 23 percent, the 10,000 or more employee band follows at 16 percent, then the 200 to 349 employee band at 9.9 percent. The 1 to 5 employee band is under-represented: 5.1 percent here against 14 percent across the database. The three largest are Westminster, City of London and Camden, together 53 percent of contacts.

1,210 of the contacts are emailable, meaning a named email scoring 70 or more at a corporate subscriber. 2,300 (80 percent) have a telephone number held, above 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.
