Update any contact by their email address.
Resend Audiences allow you to group and control your contacts in a simple and intuitive way.
From the beginning, we provided several ways to add new contacts to an audience:
Each contact has a unique ID, which you can use to update their information.
Many of our users, however, found it frustrating to update contacts by their ID.
Today, we're introducing an additional way to update contacts: by their email address.
All of our SDKs also support updating contacts by their email address.
