Principles
- Be brief. 'Saved' is better than 'Your changes have been successfully saved.'
- Be specific. 'Email sent to alex@example.com' beats 'Message sent.'
- Match the weight. Big achievements get celebration. Small saves get a quiet confirmation.
- Include next steps when relevant. 'Project created. Invite your team?'
Calibrating Celebration
| Action | Response Level |
|---|---|
| Save/update | Toast: 'Saved' (auto-dismiss) |
| Create new item | Toast: 'Project created' with link |
| Complete setup | Full-screen celebration + next steps |
| Achieve milestone | Animation + achievement badge |
| Make first sale | Confetti + metrics + share option |
Anti-Patterns
- Full-page success screens for minor actions
- Confetti for everything
- 'Congratulations!' for logging in
- Success messages that require dismissal for non-critical actions
