Improving Phoenix Email Templates with Components

In the article, Andrew addresses the shift in email templating within the Phoenix framework due to the introduction of heex templates and Phoenix.Component. He begins by questioning the necessity of the phoenix_swoosh package and proposes a new method involving components to achieve better-looking transactional emails, and a setup that facilitates generating both HTML and text bodies from a single content source. Andrew provides code snippets showing how to create a heex component for the HTML content of an email, and further code demonstrating how to render it into HTML using Swoosh for sending emails and Floki for converting HTML to text. He also emphasizes the importance of removing 'only: :test' from the Floki line in mix.exs to enable it in non-test environments and concludes by showing how to apply components to make an email layout, acknowledging the potential pitfalls of using CSS in emails. The tutorial aims to help readers set up transactional emails that are good-looking and functional, with the caveat that those designing email marketing campaigns might need more comprehensive solutions.
