True or False: An email address is a recommended value for external ID in the Braze SDK.

Using an email address as an external ID in the Braze SDK is not recommended due to privacy and security implications. An external ID should be a unique identifier that doesn't expose personal data. Using sensitive information like email addresses can lead to compliance issues and might not align with best practices for user data privacy.

Implementing a non-identifiable external ID allows developers to track user interactions without compromising personal information. This is crucial in maintaining user trust and adhering to data protection regulations. By using alternative identifiers—such as user IDs that do not relate to personal contact information—developers can leverage Braze’s features effectively without risking user data safety. Thus, the assertion that an email address is a recommended value for external ID is false.
