Develop Email Service Module

[memplethee-lab]

Overview

Build an email service module that handles sending transactional and notification emails with template support and delivery tracking.

Direction

This module should provide:

• Email template system with variable substitution
• Support for multiple email providers (SMTP, SendGrid, AWS SES)
• Queue management for reliable email delivery
• Email retry logic for failed sends
• HTML and plain text email support
• Email attachment handling
• Delivery status tracking and webhooks
• Email validation before sending

Implementation Details

The email module should abstract provider implementations behind a unified interface. It should queue emails for asynchronous delivery to avoid blocking request handlers.

Acceptance Criteria

• Email templates support variable substitution with safety checks
• Emails are queued and processed asynchronously
• Multiple email providers are supported through adapter pattern
• Failed emails retry with exponential backoff
• Both HTML and plain text versions are generated
• Email attachments are handled securely
• Provider webhooks track delivery status
• Unsubscribe functionality works for notification emails
• Email module includes detailed logging and error tracking
