About
HELO is a desktop application designed to simplify email testing and debugging for web developers by capturing and analyzing outgoing emails generated by applications during development. Instead of sending emails to real recipients, HELO exposes a local SMTP server that intercepts outgoing messages and displays them inside the application, allowing developers to inspect and verify them before deployment. This approach helps prevent common problems such as broken links, missing images, formatting errors, and other issues that often appear in production emails. It provides detailed debug views that show the email in multiple formats, including HTML rendering, plain text, raw source code, and full message headers, giving developers a complete understanding of how the message is structured. Automated validation tools check links within the email to confirm they return valid HTTP responses, reducing the risk of sending emails with invalid or broken URLs.
