National Suppression File


The DMA (UK) estimates that approximately £100 million is wasted every year by companies mailing individuals who have moved.

Launched in 2001, the Xpression (formerly NSF) is intended to be the most comprehensive suppression service available, incorporating assumed and assured gone away data from a consortium of key DM industry players.

Holding over 20 million records and receiving quarterly updates of up to 2 million new names, the Xpression file contains confirmed gone aways from the GAS file and NCOA, as well as assumed data from the Electoral Roll delete file and postal returns.

Screening data against the Xpression file offers marketers a range of benefits, including reductions in resource wastage, postage costs and returns handling. In addition, the improved accuracy of an Xpression screened file will increase campaign ROI, supporting the effectiveness of the creative and protecting the brand image by ensuring the message reaches its intended audience.
