If you're running a telemarketing campaign or you're thinking of starting one soon then you need data. Quite simply; data is the information that fuels the telemarketing campaign. The names and phone numbers of businesses and people you're going to call. The only thing is; how reliable is the data?

The source of your data can be the difference between a successful campaign and a wasted effort. This is because phone numbers on your calling list might be registered under the Telephone Preference Service. The TPS is a register of opt-out numbers that do not wish to receive telemarketing calls.
