How compliant is the data from i-4business and ZoomInfo?

No control over compliance of data purchased from 3rd parties.
No control on compliance of data acquired through acquisition of other data companies. If data is simply integrated into their database, compliance, and quality is in doubt.
Opt-outs not passed onto clients. This immediately makes client use of the information non-compliant.
Intent data obtained from Bidstream which is user behaviour captured by an ad pixel and shared through ad exchanges – highly unlikely to be GDPR compliant.
Claim to send notification emails to all contacts but when tested this did not happen.
Profile held for i-4business contains fictitious contacts with falsified i-4b email addresses. Associated LinkedIn accounts clearly showed they had never worked for i-4business.

“I have been using the i-4business database at the last four organisations I have worked at. Why? Because they are one of very few agencies who provide the right business and IT influencers and decision makers across EMEA. I know I can trust their data, and there are not many providers of data for whom I can say that!”
