Design a Marketing Email System
Design a Marketing Email System
Design a marketing email system for a ticket marketplace. The system must support running marketing campaigns that send 2 to 3 emails during a configured 15-minute delivery window. It must correctly handle users across multiple time zones and measure both email delivery success and downstream conversion to ticket purchases.
The design should cover the following areas:
Campaign Management
- How marketing campaigns are created, scheduled, and executed.
Time Zone Handling
- Strategies for correctly handling multiple user time zones, including considerations for Daylight Saving Time (DST) and scenarios with missing or invalid time zone data.
Email Sending Mechanics
- How to reliably send 2 to 3 emails within a 15-minute window while respecting external email provider limits, implementing retry mechanisms, ensuring idempotency, and enforcing user-specific frequency caps.
A/B Testing
- Mechanisms for running A/B tests across various email attributes such as subjects, templates, send times, or recommendation strategies.
Event Tracking
- How to track comprehensive email engagement metrics, including whether an email was sent, delivered, bounced, opened, clicked, unsubscribed from, or resulted in a ticket purchase conversion.
Conversion Attribution
- Methods for accurately attributing ticket purchase conversions back to specific email campaigns.
Monitoring and Observability
- Approaches to monitor system reliability, latency, and the results of A/B experiments.
