How this extension works

Use this extension to add new users to an existing Mailchimp audience.

This extension adds the email address of each new user to your specified Mailchimp audience. Also, if the user deletes their user account for your app, this extension removes the user from the Mailchimp audience.

Note: To use this extension, you need to manage your users with Firebase Authentication.

This extension uses Mailchimp, so you'll need to supply your Mailchimp API Key and Audience ID when installing this extension.

Additional setup

Make sure that you've set up Firebase Authentication to manage your users.

You must also have a Mailchimp account before installing this extension.

Billing

This extension uses other Firebase or Google Cloud Platform services which may have associated charges:

• Firebase Realtime Database
• Cloud Functions

When you use Firebase Extensions, you're only charged for the underlying resources that you use. A paid-tier billing plan is only required if the extension uses a service that requires a paid-tier plan, for example calling to a Google Cloud Platform API or making outbound network requests to non-Google services. All Firebase services offer a free tier of usage. Learn more about Firebase billing.

Usage of this extension also requires you to have a Mailchimp account. You are responsible for any associated costs with your usage of Mailchimp.
