## Visual Guidelines

## Best Practices

### Messaging Focus
- Lead with benefits, not features
- "You can now X" > "We built Y"
- Focus on user outcomes
- 65% remember better with relevant images

### Segmentation
- Don't send all updates to all users
- Segment by feature usage
- Personalize based on plan type
- Consider user skill level

### Timing
- Avoid Mondays and Fridays
- Mid-week, mid-morning works best
- Consider time zones for global users
- Space out announcements
