In informal letters, you can start with a more relaxed introduction, possibly mentioning personal details or making small talk before getting to the point.

• Example: “I just wanted to let you know that I’ve finally moved into my new apartment! I’m so excited to show it to you.”
• Example: “I hope you’re doing well! I just thought I’d drop you a quick note to say thank you for the lovely gift.”
• Tip: Feel free to use contractions and friendly, casual language, but be sure not to stray too far from the task’s requirements.
