The 👋 emoji is a subtle but effective way to say hello or goodbye in a chat. Combine it with 📸📷 for a quick photo op vibe or with 🍰🍦 to signal a sweet farewell after a party. Use 👋💌📬 when signing off on messages or emails, and 👋🎉🥂 fits celebrations where you want to wave goodbye to the old and toast the new. Perfect for casual texts and social media updates alike.
