Why the French mail market delivers

Words by: Print Power
We look at the tool French media agencies use to measure the impact of an advertisement and how long that message will be remembered for

β - score of various channels


Known as the β-score, this method of measuring media memorisation indicates how many people remember a message after the first exposure. 

The score shows that media, and not only the message, have a different level of memorisation. An overview of all media shows that cinema has the highest score (75%), followed by much lower scores for TV (17%), newspapers & magazines (10%) and posters (6%).

A separate study on the various types of mail shows a very interesting comparison: addressed (with name and address) mail scores 61% and door drops 27%.

The β-score is part of media-planning as it provides data about the wear-out of a campaign. In other word, how long should a campaign run. Using media with a high β-score will prolong the effect of a campaign. And these media will optimise the overall effectiveness of a campaign as this example shows.


The French mail market distinguish between door drops (47.9%), loyalty mail (21.4%), addressed advertising mail (17.9%) and non-retail door drops (12.7%).

The mail industry (research company Balmétrie and Mediapost and Mediapost Publicité) tells us that the French read on average 10.9 mails a week (5.1 door drops, 2.5 loyalty mailings, 2.0 addressed advertising mail and 1.3 non-retail door drops). And they distinguish between 8 different reader segments based upon the readership of addressed mail and door drops.

Other media usage and brand interest of these eight segments allows to address them in a more precise way. This insight is also appreciated by advertisers as addressed mail is among the top three of CRM tools used.
