The Postmark team has introduced a feature that allows easier template management across different environments, such as development, testing, and production servers. This new feature addresses the pain point of managing changes to templates across multiple servers, which was previously time-consuming and error-prone. With the introduction of a "Push" button, users can now easily push template changes from one server to another, either via the UI or a new API endpoint. The feature also includes the ability to manage template aliases, making it easier to reuse common elements in templates. Additionally, Postmark has released Layouts, which solves the pain point of defining reusable components in templates.
