Scaling Transactional Email: Django + SendGrid

The Technical Solution

• Infrastructure Integration: Integrated SendGrid's API into Django using custom email backends.
• Delivery Tracking: Webhook listeners for real-time reporting of bounces, opens, clicks.
• Template Management: Dynamic email templates with Jinja2 and SendGrid's template system.
• Performance: Async task queues using Celery for high-volume sending.

Architecture Decisions

We chose SendGrid for its reliability and comprehensive API. The integration allows for sophisticated email workflows including drip campaigns, automated follow-ups, and detailed analytics.
