Hi @JanE584 ,
Would you mind clarifying a bit? I'm not sure what you mean by out for review - do you mean after the email has already been sent? The only way we can edit a campaign is if it has not been sent yet. If the campaign has already been sent, you'd need to copy, edit, and resend it. Please feel free to correct me and clarify a bit more if this is not what you were referring to.
