- You can add your Custom User Properties through CSV uploads. Make sure you include an email column (which will double for a user_id column if that column is missing) and add the custom properties to the user.
- You can add as many Custom User Properties as you want. Make sure to use the same property name consistently in order to keep your users organized. Avoid using different property names with the same purpose such as locality, city, location, etc. This will prevent complications later.
