When you're talking to someone in person or on the phone, they can see the emotion on your face or hear it in your voice. When you type something, the person reading it does not know the attitude behind the words on the screen, so it's important to follow these email guidelines. Never type in all capital letters, as the other person might think you are shouting or being mean. Always proofread your work to check for typos or grammar mistakes, especially if it's an important email. If it's a formal email to an adult or someone important, capitalize at the beginning of a sentence, and don't use abbreviations. Be respectful. Don't share other's personal information or your own personal information. Make sure you are safe. Keep your note brief and to the point. Fill in the subject section at the top of the email.
