Analytics Dashboard
Each pixel has detailed analytics: Views Chart- Impression volume over time
- Hourly, daily, or monthly views
- Peak viewing times
- Trend visualization
- Countries viewing your content
- Regional distribution
- City-level tracking (where available)
- Interactive map visualization

Update pixel details:Update Name
Modify the pixel name for better organization.
The pixel URL and slug cannot be changed after creation.
What Can Be Changed
- Name: Update the internal reference name
What Cannot Be Changed

Email Tracking Considerations
Email Client Compatibility
Pixel tracking works in most email clients: Full Support:- Gmail (web)
- Outlook (web)
- Apple Mail
- iOS Mail
- Most webmail services
- Outlook (desktop) - may cache images
- Privacy-focused email clients
- Clients with image blocking enabled
Some email clients cache images or block tracking pixels. Your actual open rates may be higher than reported.
Privacy Features
Modern email clients have privacy protections: Apple Mail Privacy Protection (iOS 15+):- Preloads images on server
- Masks IP addresses
- May inflate open rates
- Location data less accurate
- Caches images on Google servers
- May delay tracking
- Obscures some data
Despite privacy features, pixel tracking still provides valuable aggregate engagement insights.
Best Practices
Naming Conventions
Use clear, descriptive names: Good Names:- “Newsletter - Weekly Tech News - 2024”
- “Email Campaign - Product Launch - March”
- “Banner Ad - Homepage - Q1”
- “Partner Content - Blog XYZ”
- “Pixel 1”
- “Test”
- “New”
- “Email”
Implementation Tips
- Place pixels at the bottom of content
- Use appropriate image attributes (width=“1” height=“1”)
- Include alt="" for accessibility
- Test pixel loading before deployment
- Don’t use multiple pixels in the same content

Best practices:- Include privacy policy link in emails

- Respect “Do Not Track” preferences
- Comply with email marketing regulations
Organization
