Final answer:
Before deleting an email, especially within a system like a Design Studio, you must ensure the email's name does not match an email currently in use which is answer C. This is to avoid deleting an active email that could disrupt business or marketing campaigns.
Step-by-step explanation:
Before deleting an email, it's important to make certain steps to ensure it's safe to remove it from your system. In the context of managing emails within a system like a Design Studio, where emails are part of marketing campaigns or business communications, one key step must be carried out before you can safely delete an email. It involves checking to make sure the email's name does not match an email currently in use. You would not want to delete an email that is active in a campaign as this could disrupt ongoing business processes or marketing efforts. Thus, the correct answer is: C. Make sure its name does not match an email in use. Removing its content or unapproving it without checking if it’s active could lead to problems. Ensuring it is not in the Design Studio merely determines its current status but does not inherently indicate it is no longer needed or in circulation.
