We're pleased to announce the launch of a powerful new postcode sector mail measurement dataset in conjunction with the geo-data experts ShoWhere. Available to all JICMAIL Discovery users, the new dataset is accessible through ShoWhere’s powerful geo-mapping platform and brings mail engagement metrics to life across 9,000 UK postcode sectors.
In a world in which $27bn worth of media spend is lost globally [1]due to poorly targeted digital advertising, geo-targeted marketing activity is more important than ever. As the original geo-targeted marketing channel, Advertising Mail (including Direct Mail, Door Drops, Partially Addressed Mail) and Business Mail has for nearly a decade been supported by the powerful media planning tools supplied by JICMAIL (The Joint Industry Currency for Mail).
Now through a partnership with the geo-data experts ShoWhere, JICMAIL’s measurement of mail engagement, attention and effectiveness is available at a new and highly granular level, covering 9,000 UK postcode sectors.

Using a predictive model based on the known demographic profile of past and present JICMAIL research panellist households managed by Kantar, ShoWhere and JICMAIL have applied this model at a postcode sector level using UK Census data.
The resulting dataset now enables JICMAIL users across agencies, advertisers, printers, mailing houses and sell-side organisations to build customised postcode sector lists based on customer locations, store locations, or areas of high mail engagement and responsiveness.
Key use cases for the new JICMAIL Geo Planning tool include:
While the JICMAIL Geo Planning tool contains hundreds of thousands of new data points, a topline look at the data set reveals that:
JICMAIL’s Director of Data Leadership and Learning, Ian Gibbs, said of the partnership, “Mail is the geo-targeted marketing channel. It uses deterministic data to drive highly accurate delivery, and now we have the granularity of data at the postcode sector level to do justice to the outcomes that the mail channel can deliver. We’re delighted that ShoWhere has helped us bring this new dataset to life and that we can bring its powerful geo-planning tools to our 370+ subscriber organisations.”
ShoWhere’s CEO Cédric Magneron, added “We are proud to partner with JICMAIL on this important initiative and to bring ShoWhere’s expertise in local modelling to the mail planning market. By reconciling multiple geo-referenced data sources, we have created a new dataset that makes JICMAIL’s mail engagement metrics more actionable at a postcode sector level. This partnership exemplifies data-driven innovation in mail marketing and demonstrates how local modelling can unlock new levels of insight from existing data.”
