What kind of user input can strings in Braze custom attributes store?

In Braze, custom attributes are designed to store and manage user information, and strings specifically can hold textual data that provide valuable insights into user preferences and behaviors. This capability allows marketers to create personalized experiences based on what users like, their activity patterns, and their interactions with content.

For instance, storing user preferences as strings can capture data such as the types of products a user is interested in, their favorite categories of content, or specific actions they have taken within an app or website. This information is crucial for segmentation and targeting, as it helps in tailoring marketing messages to individual users based on their unique preferences.

While other options may involve different data types or formats, strings are particularly suited for capturing textual information, making user preferences and behaviors the best representation of what custom attributes can effectively store.
