Suspicious Email

Hello,

I received a suspicious email (that I haven’t opened) in my gmail account.

the subject line is : Your account is bing hacked by another person.

in the text it says “Hello, I am a professional coder and I hacked tour device’s OS.

is this spam? Is it possible to hack Apple OS? What should I do next?

In looking at similar emails online it said they had access to their camera and contact list and passwords.

Help Please!
