MailChimp's Static Segment feature is now changed to MailChimp Tags. Don't worry as this is not as complicated as it seems as they have the same functionality but MailChimp Tags have some new features!
MailChimp Note: "Tags are taking the place of static segments in MailChimp. If you previously created static segments, we’ll automatically convert them to tags for you, and you'll find them on the Tags page in your list. Don’t worry, you'll still be able to send to your newly-minted tags just like you always have.
We still have regular list segments that automatically update as contacts meet the criteria you choose. And guess what? Now you can segment based on tag data!"
It is easy to now automatically create Tag(s) based on your CRM Marketing List(s), Saved Search(s), Tearsheet(s), Campaign(s), or even eCommerce Product(s) and Variation(s) you have set up in Step 1 of the Sync Profile. (What is a Sync Profile?)
Please note that if a MailChimp user exposes Groups on the Update Profile form then SyncApps will sync to the CRM List or Campaign if these Campaign(s)/List(s) to Groups have been synced prior via SyncApps.
Now let's see how it works automatically to create MailChimp Tags with SyncApps
In Step 2 of the Sync Profile, you will need to select "Use Tags" under the Segmentation Method option. Save and Reset Sync Process then Sync Now.
Since MailChimp Tags are unlimited this feature is used by subscribers to overcome MailChimp's 60 Group limitation per list if using many products or categories in your system of record to sync to MailChimp.
NOTE: Records in Tags cannot be removed automatically via SyncApps due to MailChimp's API Limitations so best practice is to just delete them all on a regular basis in MailChimp.
This will let your CRM being used repopulate each MailChimp Tag on your scheduled sync to have a trued up Segment for your Marketing Automation campaigns running on MailChimp.
