iTunes account activity being sent to my personal and work email

HI all. I bought a new mac mini and logged in with my iTunes account and I received an email on my personal one which it is linked to and also my work one which is not. I have gmail on my phone with both my personal and work emails on so I can receive from both, but my work one isn't linked to my iTunes at all so I shouldn't have received this email on my work email. I then downloaded and installed firefox and again I received an email to both my personal and work email. I haven't logged in to my work email on my Mac so there shouldn't be a reason why it is sending it to my work too. Does anyone know why this is happening?
