Building on a prior post about sending basic emails with Python's smtplib, this guide explores enhancing emails using the MIME (Multipurpose Internet Mail Extensions) standard to add functionality such as non-ASCII text, attachments, and multipart messages. By importing the MIME submodules MIMEMultipart and MIMEText, users can structure emails with detailed headers, including sender and recipient addresses, and specify subjects and bodies, which can be formatted in plain text or HTML. The process involves setting up an SMTP server connection, logging in, and sending the email using the compiled MIME data. The guide emphasizes the importance of closing the SMTP connection after sending the email and suggests exploring Python's documentation for more advanced implementations, such as incorporating attachments and alternative message formats.
