Back in June, when we launched MailChimp v3, we totally rewrote every single line of code and re-structured our database to make the system more scalable and efficient. One side effect of that effort is that we can now collect and analyze stats across our entire system really easy. We’ve put these stats to good use with our industry comparison metrics, and Chimp Charts. On that note, we’ve posted an interesting new study on list segmentation.
We recently scanned our system for MailChimp users who have used our list segmentation feature. We found 1,988 MailChimp users who sent 10,691 segmented campaigns to 8,762,207 recipients. We compared the email marketing results of those users’ segmented campaigns to the results of their non-segmented campaigns. We actually uncovered some counter-intuitive results in a few places.
