Acceptance Criteria

1. Transactional Emails

1. Event-Triggered: System automatically sends emails for: order confirmation, payment reminder, ticket download, event reminder, and waiting list offers.
2. Customizable Templates: Organizers can customize email templates per event and preview them before activating.

2. Bulk Messaging

3. Bulk Send: Organizers can send bulk emails to all attendees or filtered groups.

3. Delivery Management

4. Mail Queue: Emails are sent asynchronously with retry logic for failed deliveries and exponential backoff.
5. SMTP Required: Email sending requires a configured SMTP provider.

Tier 2 Edge Cases

• Email with invalid attendee address
• Bulk send to empty list
• Template preview with placeholder data
• SMTP provider unavailable
• Duplicate email prevention on retry
