Your Domain is one of the most important parts of your AmeriCommerce Online Store.
As such, you probably made sure to have your Domain set to auto-renew with your Registrar and don't need to be updated with notifications.
Those notifications can be disabled in your admin dashboard.
IMPORTANT: This will disable all Domain expiration notifications, so make sure that the domain will stay up to date before disabling.
1. From your Dashboard, Navigate to Settings > Store Information > Advanced
2. Check the option for "Disable Domain Notifications"
