Skip the Abstraction: Direct Transactional Email Integration in Medusa v2

By bypassing Medusa v2's notification module, developers can implement transactional email more simply using direct API integration with Resend, reducing unnecessary abstraction layers and providing greater control over email logic. The approach reveals real-world Node16 module resolution issues that can cause silent production failures—a reminder that sometimes the simplest solution outweighs architectural abstraction. This pattern is especially valuable for teams wanting straightforward, maintainable email functionality without vendor lock-in to community providers.
