What will happen if you use the same email for your sponsored ads account as your seller central account?

The correct answer is "Your sponsored ads account will automatically connect to your seller central account." This is because when you use the same email address for both your Sponsored Ads and Seller Central accounts, Amazon automatically links the two accounts. This connection streamlines the process for managing both your advertising and product listings, as you will have a unified account experience. It allows you to seamlessly integrate your campaigns with the products you're selling on Amazon, making it easier to create targeted ads and track performance. In contrast, the other options—automatically creating a Brand Store or registering for discounted services—are not directly linked to the email address connection between the two accounts.
