Suppression Data Services

Suppression services to flag contacts who are deceased, no longer at an address or who have opted-out via a preference service.

To make the most of your data, you must first be confident it is clean. There are numerous ways of achieving this and many different third party data sources can be used for cleaning and verification.

Some of the sources available via Hopewiser claim to do the same thing, but we understand exactly what they are, where they come from and which to use. Only then can you be confident your data cleansing process is as efficient as possible.



In the year to mid-2020, there were 669,000 deaths. For both Marketing suppression and compliance purposes it is important you check against the latest and most uptodate files.


Movers & Goneaways

According to the ONS, in the 12-month period to mid-2020, an estimated 3.2 million people moved between local authorities in the UK. We can provide a highly accurate way to find if any of your customers have moved and identify forwarding addresses.


Preference Services

Make sure you only contact individuals or companies NOT registered on Preference Services. Use the official opt-out registers which consumers and companies record their wish not to receive unsolicited marketing calls and mailings.


Whether data cleansing via cloud self-service, software or bureau service, you can be sure your customer data is being cleaned against the most up-to-date and accurate UK data sets. Research Data Sources to find out more.
