It's a scam
It's a scam. I'm a small YouTube creator, and their goal is to try and get you to think you can get a free microphone. After reading the e-mail, I hopped into my browser and started searching. Sure enough, sketchy website, and these reviews also match the e-mail I received. There is no Tech Zone, it's a spinoff of the legit company. Always remember that a company will not send out an e-mail asking you to do something for them. Especially if they are asking for your information. Delete the e-mail if you get one, and don't click on anything. Good luck! :)
