## Key takeaways

💡 **Remember:** Consent forms lock after sending - no edits allowed to maintain legal validity

🧪 **Try:** Send yourself a test email first - catch any issues before the real send

⚠️ **Watch for:** The big warning message about locking forms - once sent, that version is final

⚡ **Quick tip:** Set up a custom domain to send from your own email address instead of Participant Kit's default
