What's in each
B2C data — a person's name, home address, postcode, mobile, age and often lifestyle or property details such as homeowner status or income.
B2B data — company name and number, business activity (SIC code), business address, switchboard, email, size and the names of decision makers.
The rules
For consumers, texts and emails need consent and calls must be TPS screened. For limited companies, emails and texts can be sent without prior consent if you identify yourself and offer an opt-out, and calls must be CTPS screened. Sole traders are treated like consumers.
Which do you need?
