Email Universal - Universal Skill

Transactional email delivery uses a universal interface supporting SendGrid, AWS SES, and SMTP, allowing you to route messages through different providers for flexibility and cost optimization. This standardizes password resets and system notifications across your entire application suite.

Redis-based email queue processing handles reliable background delivery by queuing messages and automatically retrying failed sends. Bounce and complaint management tracks failed addresses, ensuring robust delivery for high-volume notification emails without blocking your main application.
