1,195 of the contacts are emailable, meaning a named email scoring 70 or more at a corporate subscriber. 2,765 (66 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 uses one filter. The SIC filter uses code 64203, and a company counts when it holds that code. 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.
