Can you elaborate a little more on what your exact requirement is? Currently you are able to define a workflow process, which can be either one, or two levels of approval. Both types include sending an email to approvers, when a page in ready to be published. Is this the message that you're talking about? Although at the moment the content of these emails can not be modified, this functionality has been logged as a feature request for implementation in our future releases.
All the best,
the Telerik team
