Email Writing

The anatomy of an email

A clear email has five recognizable parts: the subject line, the greeting, the body, the closing, and the signature. Each part has a job. The subject line tells the reader what the message is about before they open it. The greeting names the reader and sets the tone of the exchange. The body carries the message itself. The closing is a short sign-off such as “Best regards,” or “Thanks,”. The signature identifies you and gives the reader a way to reply — at minimum your name, usually with contact details. Here is a complete example:

Subject: Question about Monday's reading assignment Hi Sam, I have one quick question about the reading for Monday's class. You mentioned that we should look at the first two chapters, but I wanted to check whether the practice questions at the end are also required. If you get a chance, could you let me know by Thursday? Thanks, Maya

The subject line is “Question about Monday's reading assignment.” The greeting is “Hi Sam,”. The body is the two sentences in the middle. The closing is “Thanks,” and the signature is “Maya.” Every part works: the subject line names the topic, the greeting fits a familiar classmate, the body leads with the question, and the closing and signature end the message cleanly.

Subject lines that work

A good subject line is specific, brief, and action-oriented: it tells the reader what the email is about and what, if anything, it asks. Vague subject lines — “Hello,” “Question,” “Meeting” — make the reader guess, and busy readers may open them last or not at all; a blank subject line is worse, because the message cannot be identified in an inbox or found again in a search. Compare two versions of the same message: “Meeting” tells the reader nothing, while “Rescheduling Thursday's team meeting” names the topic and the action in one glance. A subject line of a few specific words is usually enough; put the details — times, places, reasons — in the body. Keeping each email to one topic keeps subject lines honest and messages easy to find later.

Greetings and closings: the register spectrum

Greetings and closings sit on a spectrum from formal to informal, and the choice signals how you see the relationship and the situation. For a first email to someone you do not know, a professor, or any official contact, formal forms fit: “Dear Dr. Chen,” with a closing such as “Best regards,” or “Sincerely,”. For ongoing contact where you have already exchanged messages, semi-formal forms work: “Hello Ms. Park,” with “Best,” or “Kind regards,”. For friends and close colleagues, informal forms are natural: “Hi Sam,” with “Thanks,” or “Cheers,”. The register is set by audience and purpose, not by a rulebook: the same person receives a formal email from you on first contact and an informal one once you know each other. If you are unsure, start formal and follow the other person's lead. In fast back-and-forth threads, greetings often shorten or disappear entirely.

The body: purpose first, details, then the ask

The most useful habit in email is front-loading: state the purpose in the first sentence, then give the details, then make the ask clear. Readers skim, and a busy reader who has to hunt for the request may never find it. Compare two openings for the same message. Weak: “I hope you had a nice weekend. I was looking at the course site, and I noticed there are two files in the resources folder, and the announcement about the deadline caught my eye, and actually I have a question about that…” Strong: “I'm writing to ask whether the lab report is due this Friday or next Monday.” The strong version states the purpose in the first sentence, and the details and the ask follow naturally: “I noticed the syllabus lists both dates. If you get a chance, could you let me know by Wednesday?” Keep paragraphs short, stay on one topic, and end by telling the reader what you need and when.

Politeness and tone

Email carries no voice or face, so short phrasing can land harder than the writer intended. A direct command such as “Send me the report” can read as rude even when no rudeness is meant; question forms soften it: “Could you send me the report?”, “Would you mind sending me the report?”, “I was wondering if you could send me the report.” In general, the more indirect the form, the softer the request — so choose the form to fit the relationship and the size of the favor. Modal verbs carry much of this politeness: “can” and “may” mark informal and formal requests, while “would” marks polite requests, so request word choice matters. Tone rules of thumb: avoid ALL CAPS, which reads as shouting; avoid text abbreviations such as “u” for “you”; and be careful with jokes, which often fall flat or sound sharp in writing. Reading a message aloud before sending is a good test: if it would sound rude said to the person's face, rephrase it. Expectations also vary by context and culture — workplaces, schools, and countries differ in how formal their email is — so observing how the people around you write is part of learning the skill. Finally, email is not private: it travels unencrypted by default, so avoid sending passwords or account details in it.
