Grouping Rules
Create rule-based grouping models that categorize events, user properties, or rows from a custom table.
Last reviewed September 15, 2026
Grouping Rules are a model type for rule-based categorization. Use them to put users into groups, classify events, or put rows from a custom table into buckets, based on conditions that you define.
Create a grouping model from Studio → New Data Model → Grouping Rules.
When to use grouping rules
- Categorize customers by behavior (for example “high value”, “at-risk”, or “new”)
- Classify events by type or source
- Build rule-based segments without writing SQL
- Convert auto-segmentation clusters into persistent rules
How it works
- Select the input data: Events, User Properties, or Custom Table.
- Define rules with fields, operators, and values.
- Set the output group label for each rule.
- Choose an output target, typically a user or event property.
- Schedule the model or run it on demand.
Vendo evaluates the rules in order. The first matching rule wins.
From auto-segmentation
If you use Auto-Segmentation to discover natural clusters, you can convert any cluster into a grouping rule with one click. This turns an ML discovery into a persistent segment that you can activate.
