2500 Diamonds is at it again!

I just got the phishing scam telling me I had purchased a Mobile Legends game for $49,96. Yes, you saw it right...just as it appears on the "receipt", there's a comma where a period should be. I looked at the whole thing again and noticed it stated: "Notification : Your purchase today has been successed." It claimed the purchase would be paid by my linked credit card. I opened my Wallet and checked the purchases, but didn't see anything suspicious.

My question is this, If I delete this phishing email, is it GONE from my email, computer, iPhone or did I infect or download something malicious by merely opening the email message? Am I OK or do I need to do something else?
