How do you write informal email?

To write an informal email, start with a friendly greeting, like "Hi" or "Hey," followed by the recipient's name. Use a casual tone and conversational language, sharing your thoughts or updates in a relaxed manner. Keep your sentences short and use contractions, emojis, or exclamation points to convey warmth and enthusiasm. Finally, close with a friendly sign-off, such as "Best," "Cheers," or "Talk soon," followed by your name.
