Use the EXM Delivery Cloud service

Current version: 10.4

In the Email Experience Manager, you can choose between using the EXM Delivery Cloud or the Custom SMTP to send your email campaigns.

The EXM Delivery Cloud handles the complexity of email delivery for you and ensures that your email campaigns avoid getting blocked by your recipients’ Junk, SPAM, and Clutter folders but instead arrive quickly in their inbox.


For configuration support and email dispatch troubleshooting, refer to the standard Sitecore support channels. We also provide reactive support to all subscription holders focusing on any misconfigured accounts and high bounce- or spam-rate email campaigns.
