Taguchi removes the need for you to run complex queries in data warehouses or external statistical suites with best in class targeting and personalisation capabilities. It lets you easily query your data to identify the most relevant subscribers and enables you to quickly send them the most appropriate content.
For example, you may be sending an email to all of Australia but you wish to display a hero image specific to each state. Using a segment would be the most efficient way of doing this, rather than creating several email activities. A segment allows you to do this in one single email activity.
You could create segments for each state, hero image items for each state and define the segments to their correlating hero image item to achieve subscriber specific segmentation (e.g. The ACT hero image would have the ACT subscriber segment selected and so on).
