Overview
Tags are simple labels you attach to contacts for segmentation, reporting, and workflow conditions (for example triggers when a tag is added or removed).
In the app
Manage tags at #/tags. Apply tags from the contact list or contact detail. Workflows support actions such as Add tag and Remove tag.
REST
Tag routes are exposed under the tags REST base (CRUD and assignments as implemented in TagsController).
For list membership and dynamic rules, see Contact lists.
