Hey Max! (lub jakieś inne imie)
I'm writing this email to tell you about the new shirt I bought. It's green and has my favourite band's logo on it! Isn't that cool? I know you also listen to their music, so I wanted to ask if you'd like to buy it as well. I bought it online so I can send you the link to it. I hope you're doing alright, reply and let me know if you want it!
Sincerely (twoje imię)
Mam nadzieję że o to ci chodziło, jeśli jednak źle zrozumiałam polecenie to proszę napisz ,a ja spróbuje je poprawić^^
