The gesture of greeting emojis like 👋 and 🤚 do more than say hello; they set the tone for a chat. Use them in a quick DM to start a conversation or in a group chat to acknowledge someone without interrupting. Pairing 👋 with 😊 or 🙌 adds warmth, while 👋🤚 can feel like a virtual high-five or a casual wave goodbye. Handy for casual check-ins and friendly welcomes alike.
