Background Email Processing User Stories & Acceptance Criteria
User Stories
Primary User Stories
1. Automated Email Processing
As a user with configured email folders
I want my emails to be automatically processed in the background
So that I don't have to manually trigger email organization
Acceptance Criteria:
- Background task runs periodically to process emails for all users
- Only processes emails in folders with
organize_enabled = true - Processes emails according to all folder rules, moving emails as needed to the appropriate folder
- Respects priority field for folders
- Marks processed emails to avoid reprocessing
- Updates folder pending counts after processing
- Handles processing errors gracefully without stopping other folders
- Respects folder priority when processing (high priority first)
2. Email Processing Status Tracking
As a user
I want to see the status of email processing
So that I can understand how many emails are pending organization
Acceptance Criteria:
- Pending email count is displayed for each folder
- Count updates in real-time after processing
- Processed email tracking prevents duplicate processing
- Email processing history is maintained
3. Batch Email Processing
As a user with many emails
I want emails to be processed in batches
So that the system doesn't become unresponsive with large mailboxes
Acceptance Criteria:
- Emails are processed in configurable batch sizes
- Processing progress is tracked per batch
- Failed batches don't affect other batches
- System resources are managed efficiently during processing
4. Error Handling & Recovery
As a user
I want email processing errors to be handled gracefully
So that temporary issues don't stop all email organization
Acceptance Criteria:
- Individual email processing failures don't stop folder processing
- Connection errors to IMAP servers are retried
- Transient errors are logged but don't halt processing
- Permanent failures are flagged for user attention
- Error notifications are sent for critical failures
5. Processing Controls
As a user
I want control over when emails are processed
So that I can manage processing during preferred times
Acceptance Criteria:
- Users can enable/disable automatic processing per folder
- Users can trigger manual processing for specific folders
- Processing can be paused and resumed
- Processing schedule can be configured
Secondary User Stories
6. Performance Monitoring
As a system administrator
I want to monitor email processing performance
So that I can identify and resolve bottlenecks
Acceptance Criteria:
- Processing time metrics are collected
- Success/failure rates are tracked
- Resource usage during processing is monitored
- Performance alerts are sent for degraded performance
7. Accessibility
As a user with disabilities
I want email processing status to be accessible
So that I can understand processing through assistive technologies
Acceptance Criteria:
- Processing status updates are announced by screen readers
- Visual indicators have proper contrast ratios
- Processing notifications are keyboard navigable
- Error messages are clear and descriptive
