I want to write good business email I have been working for this foreign company for 2 years now. Recently I have got a offer from another company and planning to work for that company. My future boss asked me to improve my English since I will have to use more english. I am so worried now... I wrote business email in English yesterday and I asked my sister to edit... After her edit I found that it is so different from mine. I realized that what I wrote is very childish and unprofessional. I have decided to focus on improving English from now..
