# Activate Profiles Data

Once you create [cohorts]({{< ref "profiles/concepts/cohort.md" >}}) and run the project successfully, you can use the Profiles **Activations** feature to sync your target customer data to the downstream marketing tools like Braze, Mailchimp, etc. This will help you make informed decisions, run personalized marketing campaigns, and enhance the overall customer experience across multiple platforms.

## Prerequisites

- [Import the Profiles project]({{< ref "profiles/management/import-from-git.md" >}}) from your Git repository and run it.
- For the warehouse used for your Profiles project, you must create the RudderStack schema and grant permissions to it. See the detailed steps for each warehouse:

  - [Snowflake](https://www.rudderstack.com/docs/sources/reverse-etl/snowflake/#creating-the-rudderstack-schema-and-granting-permissions)
  - [Redshift](https://www.rudderstack.com/docs/sources/reverse-etl/amazon-redshift/#creating-the-rudderstack-schema-and-granting-permissions)
  - [Databricks](https://www.rudderstack.com/docs/sources/reverse-etl/databricks/#creating-the-rudderstack-schema-and-granting-permissions)
  - [BigQuery](https://www.rudderstack.com/docs/sources/reverse-etl/google-bigquery/#creating-the-rudderstack-schema-and-granting-permissions)
