Luckily a lot of clever marketers do segment in different ways. I say luckily because relationship building in email marketing is fundamental in email marketing nowadays. Capturing information via relevant messages by creating valuable dialogues which create respect between the brand and the customer. It is not only about capturing and collecting as much data as possible, but also about using it in the right way. Segmenting is a way of working intelligently with your data in order to optimize your relationship and of course your return on investment.
