Our mailing list data is comprised from our market research and three main data sources; Companies House, BT and Royal mail. After that 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 of our verification process would be validating our data against Companies House and then Royal Mail for address details. Initially we check against ‘gone away’ files which means that we can ensure further accuracy and suppress relevant records. Next, our contact centre validates fields daily. For instance additional fields are then verified before the contact is updated on our base Additional fields are also verified, including 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 of 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 before the despatch of the mailing lists to our clients.


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. With this in mind what does each lawful ground mean?
