## How come I don't see event data from a send we did a couple months ago?

Understanding event data retention:

1.  Data Retention Rules:

- Event data has specific retention periods
- Different event types may have different retention periods
- Retention periods vary by account type

1.  Best Practices for Historical Data:

- Set up webhooks to capture events in real-time
- Store important data in your own systems
- Use scheduled reports for long-term analysis
- Export critical data before retention limits

1.  Recommendations:

- Implement webhook data collection
- Set up regular data exports
- Consider using the Events API
- Store historical data in your own database

Note: For specific retention periods and data access details for your account type, please consult your Email account manager or support team.

## I'm not seeing the data I'm looking for in the Email UI. Can you assist?

Several factors can affect data visibility in the UI:

1.  Common Visibility Issues:

- Time range selection
- Filter settings
- Account permissions
- Data aggregation rules

1.  Troubleshooting Steps:

- Verify your selected date range
- Check all applied filters
- Confirm your account permissions
- Consider using the API for raw data access

## Why are my bounce counts different when looking at Metrics vs calculating from events?

Bounce count differences can occur due to several factors:

Events report all bounces as a Bounce event with a corresponding bounce classification. 

Metrics separates out Admin Bounces as a separate metric to the Bounce metric

1.  Timing Differences:

- Metrics are processed and aggregated in real-time
- Events may have slight delays in processing
- Time zone settings can affect how data is grouped

1.  Categorization:

- Metrics and events may categorize bounces differently
- Some events may be rolled up in aggregate metrics
- Certain bounce types may be filtered differently

1.  Best Practice:

- Use consistent time ranges when comparing
- Consider which bounce types you're including
- Check your filtering settings

## Why can I only see data from the last 10 days?

Email maintains different data retention periods based on data type:

1.  UI and API Metrics:

- Rolling 10-day window for detailed metrics in the UI
- Summary metrics available for longer periods
- Historical data accessible through scheduled reports
- Retention periods may vary by account type

1.  Best Practices:

- Set up scheduled reports for long-term data needs
- Export important data regularly
- Use the events API to collect real-time data for your own storage
