What is mime-mail?

The mime-mail project is a tool for programmers who need to build email messages from scratch in their code. Instead of dealing with the messy formatting rules that make emails work across different programs, developers can use this library to assemble well-structured messages with text, attachments, and HTML. At its core, the library handles the heavy lifting of the MIME standard, which is the underlying system that lets emails contain mixed content like plain text alongside images or documents. A developer provides the pieces, such as who the email is for, the subject line, and any files to attach. The library then packages everything into the correct format so that email servers and inbox applications can properly read and display the final message. This would be useful for anyone building an application that sends automated emails to users. For example, if a startup is building a billing system that needs to email PDF invoices to customers, or a PM is overseeing a feature that sends users a weekly data report as an attachment, this tool handles the technical formatting behind the scenes. The developer writes a few lines of code to define the parts, and the library outputs a valid email message ready to be sent through an email service. The project is written in Haskell, which is a programming language known for its strict approach to correctness and reliability. The README does not go into further detail about specific features or advanced configurations, keeping the documentation focused on the library's single, clear purpose of composing properly formatted email messages.
