What tone should I use in an email This notebook serves as a collection of questions that I have in the tone used in an email. Please feel free to weigh in either on these questions or my grammar. -- This question has puzzled me for a long time: when writing an email, you are, in fact, trying to talk to the person and therefore a causal and even colloquial language should be acceptable. However, I feel embarrassed when my email has a lot of "I" and "is(be)" is used. Sometimes, I perceive such worry as I am too conscious about my English learner identity, thinking proficiency will resolve the problem. I am really curious about what will be the reaction of a native speaker when one gets an email filled with "I" and colloquial languages? As a native speaker, would you rather rephrase and avoid too many "I"s or it really does not matter? For example, if I have already used many sentences that start with "I", I will change "I have signed the document also" to "The document is signed." From my perspective, the former sentence is more positive in attitude but the latter one is concise and (maybe) professional. What is your opinion on such issue, i.e. intentionally diversifying sentences but sounded less as a person. Many thanks! (I might talk too much on a simple question but hope more words would translate well into practicing more)
