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.
You didnt sat what an Auto-update segment is.
There is a real lack of information on Mailchimp’s website about when an audience is updated. If I create a segment [for example] based on campaign activity, is the audience set when I schedule the campaign or is it updated when the campaign is sent?
