Whenever I received an email from unknown people that tell me to take action, especially about my wallet, the only thing I do is hit spam, this is basic, you are not supposed to receive uninvited emails, especially on emails that you have not subscribed in, all uninvited emails should go to spam because that's what they are spam emails, never take action on these spam emails even if they have compelling titles on it, if many will do these spammers/scammers will never get victims from emails they've sent
If they had followed all the instructions, no crypto user would have fallen victim to the scam. But many times they panic and open any kind of wallet related email and follow all the steps, which end up falling victim to the scam.
It is not always that these emails are sent to your subscribed email, but sometimes the data of many important websites is leaked and your email is stolen from there too. After that scammers use those emails to spread such phishing.
