Can I make changes to my email marketing content after it has been reviewed? After it has been sent?

Even if a email marketing has been reviewed, you can still edit it but once a email marketing has been sent, you will need to clone it to use the content again. If you see yourself using a particular email marketing content frequently, then save the content to Library as a template for future use.
