I want to send email through delivery activity in campaign workflow. I am using sandbox instance of Adobe Campaign Cloud.
Following error is generated after confirming the delivery in campaign dash board :
Error while executing the method 'Play' of service 'nms:delivery'.
There are two possibilities:
1. You don't have delivery standard package installed in your box.
2. You'r instance is not configured to send the email delivery.
Please check with you product owner if this is provided by Adobe please open a ticket else it's on premise then ask your support team.
Which version of Adobe Campaign are you using? Is the sandbox configured to be able to actually send emails?
