Thank you for reaching out to the Community!
To see what is being sent to your recipients you can preview your email before sending. Click here for an article on how to preview your campaign. You can also view which campaign is being sent to your contacts by clicking on on the reporting tab and selecting the campaign name. Click here for an article on reporting for an email campaign.
To edit your campaign it does have to be in draft status. You can click on the title of the draft campaign or click the more tab and select edit. I have attached a screenshot.
Please let us know if you have any further questions!
