Feedback on ACS Email retirement: please preserve an Azure email option

Jens Kersting 0

Hello Azure Communication Services team,

I would like to share feedback on the announced retirement of ACS Email on September 30, 2028: https://learn.microsoft.com/en-us/azure/communication-services/acs-retirement-and-breaking-changes-guide

ACS Email is a cornerstone of our business. We use it for crucial communication with our customers, and we chose Azure because we trust its infrastructure to be reliable and available for the long term. Losing this service would have a significant impact on our business.

The alternatives in the guide do not appear to offer the same Azure-managed, application-to-external-recipient email experience. In particular, Microsoft 365 High Volume Email is described for internal sending, while Exchange Online serves a different, mailbox-oriented use case.

If the retirement decision is still open to reconsideration, we would sincerely appreciate Microsoft keeping ACS Email available. If that is not possible, could Microsoft offer a standalone Azure email service with capabilities comparable to ACS Email for communication with external customers?

We would be grateful if you could pass this feedback to the product team and share whether either option is being considered. Thank you for listening and for the work your team has put into ACS Email.

Thanks,
Jens

Hello @Jens Kersting ,

Thank you for sharing your detailed feedback regarding the retirement of Azure Communication Services (ACS) Email.

We understand your concern, particularly for workloads that rely on ACS Email for application-to-customer communications and where maintaining an Azure-based solution is important to your architecture.

Based on the currently published Microsoft guidance, ACS Email is scheduled for retirement on September 30, 2028. The retirement guide provides the currently recommended migration options for affected ACS services.

We also understand your point that the available alternatives may not provide an identical replacement for every ACS Email scenario, especially where the requirement is application-based email delivery to external recipients.

Regarding your questions about whether Microsoft will reconsider the retirement of ACS Email or introduce another standalone Azure email service with comparable capabilities, there is currently no published information that confirms either option. Therefore, we would not want to speculate about future product plans.

We appreciate you taking the time to provide this feedback.

For the latest information, migration recommendations, and any future updates related to ACS Email retirement, please continue to refer to the official documentation:
