[ Security ] Open Question : My cousin has been sending me emails harassing me, is there anything i can do to stop him?

My cousin who is a divorced guy has been sending me emails harassing and bashing and humilating me for my choices. So I'm going to be in an arranged marriage because I had very bad luck with girls here in the states so my aunt and my mother is going to find me a wife from vietnam. My cousin is also vietnamese and he is bitter because he didn't listen to his mother to marry a girl from vietnam in an arranged marriage and he end up marrying an american girl who divorced him 3 years later. Almost all of the few vietnamese guys in my town who got an arranged marriage lived happy marriage lives so arranged marriages seem to work out in the vietnamese culture. How come my cousin has to bring me down just because he is jealous of me ?? He stated in an email, Just in case you think I'm jealous, I'm not jealous of your life, You can have your life queer no one wants it and no one wants an arranged marriage you barbaric pig. How come he can't leave me alone ? Is there anything I can do to stop him from sending me emails ??
