To tell if an Amazon investment link is real, you can do the following:

1. Check the URL: Make sure the URL you visit is the official Amazon website. Amazon's official website is www.amazon.com. If the investment link you received is not from this URL, please be cautious.

2. Check the email: Amazon's investment team usually contacts you via an official email address (for example, [email protected]). Please check carefully whether the email you received is from this address or whether the email contains Amazon's official logo.

3. Find information in Amazon Seller Center: If you have received an investment link, you can check the relevant information in the "Partners" or "Investment Information" section of Amazon Seller Center. If you see information related to the investment link you received in the Seller Center, then the link may be real.

4. Contact the investment team: If you are still unsure of the authenticity of the investment link, you can contact the Amazon investment team directly. You can find the contact information of the investment team through the "Contact Us" page on Amazon's official website.

5. Search for information about Amazon investment fraud: Search the Internet for information about Amazon investment fraud and learn about other people's experiences and suggestions. This will help you determine whether the investment link is real.

In short, to determine whether the Amazon investment link is real, you need to carefully check the website, email, Amazon seller center and other information, and contact the investment team for more information. At the same time, understanding the relevant information about Amazon investment fraud can also help you avoid being deceived.
