Transactional Email Service

A self-hosted transactional email service with secure SMTP and Spring Security access control, so every app sends mail through one tracked channel.

The Challenge

The client needed a dedicated email service backend to handle transactional emails — account notifications, order confirmations, and system alerts. They required a secure, reliable service that could integrate with their existing applications and ensure consistent email delivery without depending on third-party email SaaS platforms.

Our Approach

Daiviksoft built a focused Spring Boot email service that handles transactional email delivery via SMTP. The service provides a secure REST API for other applications to trigger emails, with Spring Security protecting the endpoints and Spring Mail handling the actual delivery. The architecture keeps email logic centralized and auditable.

Key Deliverables

  • Centralized transactional email API
  • SMTP-based email delivery
  • Spring Security-protected endpoints
  • Clean REST API for triggering emails from any application
  • Lightweight, focused service architecture

Results & Impact

The client gained a reliable, self-hosted email service that integrates seamlessly with their applications. Centralizing email delivery through a dedicated service improved deliverability tracking and simplified email template management.
