# Membership: custom properties and segmentation attributes

> Bring your own customer data into Lobyco and use it in the Segment Builder.

*16 July 2026 · Membership*

You can now bring your own customer metadata into Lobyco and use it directly in the **Segment Builder**, without any Lobyco engineering involvement.

Retailers already collect data that is specific to their business: loyalty tiers, store preferences, employee types, join dates and more. Custom segmentation attributes give you a generic, scalable way to import that data, so marketers can act on it straight away.

## What's new

* **Custom property definitions** — define the structure of your custom attributes (String, Number, Date or Boolean) before importing any data. Up to 30 custom attributes are supported per retailer.
* **Flexible import options** — populate custom properties in bulk, update them for a specific customer, or include them when creating a new customer.
* **Visible on the customer profile** — once imported, custom properties appear in the **Overview** tab of a customer's profile.
* **Available in Segment Builder** — custom attributes show up under a new **Membership – Custom** category, with operators tailored to their data type. For example, `Contains` and `In` for strings, `Between` for numbers and dates, and `Yes`/`No` for booleans.
* **Usable in orchestration journeys** — add custom attributes to an **Enrich** block to pass values downstream to a Feed, Email or other journey step. A customer's nickname or loyalty tier, for example.
