Posta in Arrivo - agent z

Hi agent z

I saw you have logged in but you didn't reply to my message here (click the green link)

I am one of the English experts; even though I don't speak Russian, it is my job to make sure the English text is grammatically correct; once that is the case, I will set a poll to ask others to confirm that the meaning is correct.
Could you help me improve your text please? Thanks!
