Email Tracking System
Implementation and documentation of a comprehensive email tracking system for marketing and transactional emails.
- C#
- .NET
- REST API
- MS SQL
- JavaScript
The Challenge
Without insight into email recipient behavior, the marketing team was operating blind. Key metrics such as open rates, click behavior, and bounce rates were missing – essential for optimizing campaigns and improving deliverability. Additionally, comprehensive documentation was necessary for the operations team and future developers.
The Solution
Development of an end-to-end email tracking system with complete technical documentation.
Tracking Mechanisms
- Pixel Tracking: Integration of an invisible 1x1 pixel image in emails, whose retrieval is registered by the server and correlated with the email ID.
- Link Wrapping: Automatic rewriting of all links through a redirect service that captures clicks before forwarding the user to the destination.
- Webhook Integration: Connection to SMTP providers (SendGrid, Mailgun) to capture bounce, spam, and unsubscribe events.
- Real-time Processing: Asynchronous processing of tracking events via message queues for maximum performance.
The Result
A performant tracking function seamlessly integrated into the existing system. The marketing team now receives real-time insights into open rates, click behavior, and deliverability of their campaigns.
