Email Masterfile has been put together using core data from 3 separate sources – Companies House, Thomson Directories and Dunn & Bradstreet. The core data has then been enhanced through a telemarketing process, during which email addresses have been solicited from contacts on the file. The contacts are informed of the use to which the email addresses are to be put. A confirmation email is sent to each contact at this point, but the user is not required to take action to be include on the list. This si known as “Confirmed Opt-in”.
The file has 360,000 email addresses on it, that are selectable by SIC, job function, company employee size, company turnover and geography. Please see Matrices for headline counts of email addresses on this file.
