What problem does it solve?

Email delivery in Rails apps can block requests and lead to unreliable notifications; this skill provides a structured approach to building, sending, and testing emails with ActionMailer using async delivery and templates.

Core Features & Use Cases

  • Automated email delivery and testing workflows for transactional and notification emails using ActionMailer with async processing via SolidQueue.
  • HTML and text templates, attachment handling, mailer previews, and robust test coverage to ensure correct content and delivery.
  • Use Case: When a user signs up, send a welcome email without blocking user requests, while still validating content in tests.

Quick Start

Configure ActionMailer with a default from address, create mailer classes and templates, and enable async delivery with deliver_later.
