When a new member joins Slack, the buzz often comes wrapped in 🔔📬➕ or 📧➕📨 emojis to signal added notifications or messages. Use 💬➕📣 in team chats to hype up announcements, or drop 💻➕🔄 when syncing updates or adding apps. These combos fit well in onboarding threads or quick updates when someone’s been added to a channel or workspace.
