A campaign is a marketing program that you create in CloudPortal Business Manager to introduce new products to customers who sign up during the campaign period to expand the customer pool, or to retain customers by giving them additional offerings.
Trial users who sign up during the campaign period are given a promotional code that they use to sign up. This is a required code that trial users should provide. These customers are assigned a Trial account type and they can sign up by entering the promotional code in the text box provided in the Sign-up page.
When the trial period expires, the account owner is notified by Email. The account's resources like running VMs, templates, snapshots, storage etc. are stopped. These resources are released into the system after a certain period of time, which can be configured.
