On 01-Nov-2017, the Dyn provider integration with the Email Delivery service was discontinued. Starting May-2017, new orders on Email Delivery service (Dyn) for EXM 1.0–3.3 are no longer available in App Center.
Existing customers who use Sitecore MTA and have EXM 3.3 or an earlier version must either upgrade their solution to EXM 3.4 or a later version, or start using a custom SMTP.
To get acquainted with the features for both options before making a decision, read an overview here: The Sitecore Email Cloud compared to the custom SMTP.
Sitecore is committed to improving EXM so that our customers can enjoy a robust email marketing platform. Significant improvements in module functionality, platform stability, and overall UX design have been implemented in version 3.4. Should your organization require the use of EXM 3.0–3.3, please contact your local Sitecore representative at the appropriate email address found here: http://www.sitecore.net/company/contact-us.
EXM 3.4 is compatible with Sitecore XP 8.2. To upgrade to EXM 3.4:
The minimum requirements for the Sitecore Email Cloud service are Sitecore XP 8.2 Initial Release and EXM 3.4 Initial Release. However, we recommend that you upgrade to the latest Sitecore XP version with a compatible EXM version.
