The WooCommerce Addon enables you to sell email accounts using WooCommerce Plugin per domain and not per user account. Hence, an individual can have multiple domains with each having a unique subscription configuration (e.g. number of email accounts per domain and disk space per email account).
It integrates with:
Whenever an email product subscription expires, the domain is deactivated (can’t be used to create new email accounts) and existing email accounts are suspended. When the subscription is renewed, the domain is reactivated (can be used to create new email accounts) and existing suspended email accounts are unsuspended.
