So I have received a trademark infringement email from a company saying that their trademarked word is used in one of the product in my amazon affiliate website. (not even the product, just their word in the product) Of course I removed that product to avoid any further issues. But the letter requires me to send a signed document which states i have to pay legal fees even after i have deleted the product. I have not replied to them yet. Should i delete the product from the website and not respond? Any advice would be helpful.
