Hi @WENMAO
The best next step you can do is contact Shopify Support directly and have them double-check about this email and make a verification.
You could refer to this link, log in to your store account then type in a topic in the search bar, for example, "verification email " and select Search. On the following page, scroll down to Get Support and click Continue and you’ll be presented with options to contact their Support via chat, email, or schedule a call-back.
If you find this answer is helpful, please mark it as a solution.
All the best.
