The two Mailchimp segment types
Auto-Update segmentation is available to all Mailchimp subscribers (even if you’re on the free account). Mailchimp Pro subscribers get access to Advanced segmentation in addition to the Auto-Update segmentation. The basic differences between Auto-Update segmentation and Advanced segmentation are:
- Auto-Update segmentation allows a maximum of five conditions.
- Auto-Update segmentation allows either of AND or OR logic.
- Advanced segmentation allows for nested conditions and allows for AND and OR logic within the same segment.
Should I use Auto-Update segmentation or Advanced segmentation?
Whenever possible, use Auto-Update segmentation. The reason for this is that Advanced segmentation can become very complex and unwieldy very quickly. If you have a list with many fields of reliable data (over about 30 fields) and over several hundred thousand subscribers is it usually beneficial to use Advanced segmentation.
