Our mailing list data is comprised from our market research and three main data sources; Companies House, BT and Royal mail. We have a strict verification process to ensure complete accuracy. This includes verifying new contacts, identifying and updating companies which have dissolved, changes and updates of Directors as well as other segmentations.


The first stage to our verification process would be validating our data against Companies House and then Royal Mail for address details. Checking against ‘gone away’ files means that we are able to ensure further accuracy and suppress relevant records. Our contact centre validate fields on a daily basis. Before a contact is added to our base, additional fields are verified and these can include job titles, positions and personal B2B email addresses. Our market research team then verifies all emails by running them through our in house system which is also carried out at the point of order. The final piece to our research is to ensure telephone lines are live and in use. We do this by verifying this with BT. To sum up, all of the above steps are performed within 2-3 days prior to despatch of the mailing lists to you, our client.


When you process data you are required to determine a lawful basis beforehand. There are 6 lawful grounds. Contract, Legal obligations, Consent, Vital Interests, Public task and Legitimate Interest. There is no such basis which is better or more important than another. What does each lawful ground mean?
