Business value

Marketers often receive customer lists from various systems and need to act quickly. These lists typically lack the attributes required for dynamic segments or aren't part of an existing Dataverse view.

This feature enables marketers to build static segment groups with up to 200,000 members in each static group using data from any source. Marketers can upload CSV files, use the API to create segments as part of a workflow, or select contacts from a Dataverse view.

Feature details

Create static segments of up to 200,000 members by:

• Uploading a CSV file to match contacts or leads in Dataverse.
• Using the API to upload a CSV file and match contacts or leads.
• Selecting contacts or leads directly from the Dataverse grid.

To define static segment membership using a CSV file, create a contact or lead-based segment, then go to + Add a new group > Upload CSV.
