| SUMMARY: We surveyed more than 1,000 businesses about what data they collect and use for email personalization. A delicate balance is struck between granting a marketer’s wish list and not asking for so much information that it creates friction for the customer. This week’s chart looks at data collected and how companies are using it. |

Thanks for another piece of data backed analysis. I love that about Marketing Sherpa. I do worry a little that in this case, we're seeing a "looking for the keys under the lamp post" kind of phenomenon. Here's what I mean: we've found that without collecting any of that PII, you can get much better personalization and relevance. Pay attention to what people want, not who they are. And they seem to react better. Ironic that this came out today as today is the Email Marketing and Personalization track of eTail 2011. If you're a retailer and in the neighborhood, should be a good set of discussions.
