-The Azure Communication Services email service is designed to support high throughput. The service imposes initial rate limits to help customers onboard smoothly and avoid some of the issues that can occur when switching to a new email service. We recommend that you use Azure Communication Services email over a period of two to four weeks to gradually increase your email volume. During this time, closely monitor the delivery status of your emails. This gradual increase enables third-party email service providers to adapt to the change in IP for your domain's email traffic. The gradual change gives you time to protect your sender reputation and maintain the reliability of your email delivery.

-### Rate limits for email
+We recommend gradually increasing your email volume using Azure Communication Services Email over a period of two to four weeks, while closely monitoring the delivery status of your emails. This gradual increase enables third-party email service providers to adapt to the change in IP for your domain's email traffic. The gradual change gives you time to protect your sender reputation and maintain the reliability of your email delivery.
 
-We approve higher limits for customers based on use case requirements, domain reputation, traffic patterns, and failure rates. To request higher limits, follow the instructions at [Quota increase for email domains](./email/email-quota-increase.md). Higher quotas are available only for verified custom domains, not Azure managed domains.
+Azure Communication Services email service supports high volume up to 1-2 million messages per hour. High throughput can be enabled based on several factors, including:
+- Customer peak traffic
+- Business needs
+- Ability to manage failure rates
+- Domain reputation
 
-The following table lists limits for [Custom domains](../quickstarts/email/add-custom-verified-domains.md).
+### Failure Rate Requirements
 
-| Operation | Scope | Time frame (minutes) | Limit (number of emails) |
-|---------|-----|-------------|-------------------|
-|Send email|Per subscription|1|30|
-|Send email|Per subscription|60|100|
-|Get email status|Per subscription|1|60|
-|Get email status|Per subscription|60|200|
+To enable a high email quota, your email failure rate must be less than one percent (1%). If your failure rate is high, you must resolve the issues before requesting a quota increase.
+Customers are expected to actively monitor their failure rates.
+
+If the failure rate increases after a quota increase, Azure Communication Services will contact the customer for immediate action and a resolution timeline. In extreme cases, if the failure rate isn't managed within the specified timeline, Azure Communication Services may reduce or suspend service until the issue is resolved.
