The headline-grabbing conclusion of this INSEAD study is that ecommerce companies with tightly-integrated tech stacks grew more slowly under GDPR than companies with loosely coupled stacks.  The academic jargon is nearly impenetrable but the authors seem to argue that tightly integrated stacks are harder to change, and this resulted in worse customer experience when GDPR enforcement began.  It’s intriguing if not entirely convincing.

Just over one-third of marketers plan to either buy a new CDP (21%) or replace an existing one (13%) this year, according to this Optimove survey. Unfortunately, it doesn’t report how many have a CDP already in place, which would put the other values in perspective. It does seem that CDPs are a relatively low priority: they rank sixth on the list of new systems and eighth on the list of systems to replace.
