Email Addresses as Unique People

You’re probably used to identifying people by ID—a value that represents your audience as customers. Now you can identify people by their email addresses, helping you start conversations with people before they make a purchase, create an account, or subscribe to your service.

Email Addresses as Unique People

When you use email as your workspace’s unique key, each email address represents a unique person, helping you manage your audience directly by email address. To use email addresses as your unique key, create a new workspace and choose to identify people by “Email address”.

If you want to explore the possibility of converting an existing workspace to identify people by email address, contact win@customer.io.
