The original implementation credit belongs to the first worker-mailer project.

This project includes its own improvements, packaging, docs, branding, and ongoing work, but the initial implementation and original public package deserve direct credit to zou-yu and the original worker-mailer release.

What is being credited

The starting point came from the original package and repository.

The original project introduced an SMTP client for Cloudflare Workers built on Cloudflare TCP sockets and published it under the MIT license. That initial work is the foundation this project acknowledges here.

Improvements here do not replace the original attribution.

This site and package can add maintenance, documentation, release work, branding, or new improvements over time. None of that changes who should receive credit for the initial implementation that started the project line.

The original SMTP implementation credit goes to the first worker-mailer project.
The original npm package and repository links are kept here on purpose, not as a footnote.
Subsequent improvements can be recognized without erasing the original authorship.
