Are you keeping a log of stats for promoting 1:1 printing over online alternatives? One of the categories of stats I keep seeing recently is how a high percentage of online targeting is completely mistargeted.
Most recently, Blue Research noted that not only is online advertising mistargeted, but consumers are getting so irritated by irrelevant advertising that they are abandoning the brands doing it.
Here’s the latest:
96% of consumers report receiving mistargeted information or promotions. While that’s not new, many are so fed up that they are abandoning brands as a result. 
Sure, there is the occasional database mess-up in 1:1 printing, but overall, targeting in print is highly accurate. The contrast with online mistargeting can create a powerful impression on customers thinking of reducing print volume in favor of electronic alternatives.
