The following are some of the important aspects when writing/replying emails.

1. Always start with a salutation, like Dear Sir/Madam.
2. Write smaller paragraphs with logical division between them.
3. Sometimes it helps if you write your points as a numbered list, so that the person can reply based on the points you have written.
4. If you are sending an email to a Professor on behalf of many students, ensure that the emails of all the other students are included in cc (carbon copy).
5. When you reply back, make sure you send “reply all” if all the people in the list are to be informed about your reply.
6. If you are writing a formal email, end the email with a positive note, such as “Anticipating a positive response”, etc.
7. Read the email once before sending it. Most of the times we forget to attach files!
8. If you have received an email from a very senior person (in age or experience), wait for sometime before you reply back. Sending immediate replies may lead to some errors/mistakes.
