Eärendil

Eärendil is a Markdown-based HTML email API written in Python. It allows users to draft an email message in Markdown and send it as a rich email viewable as both HTML and plaintext.

My primary motivation for creating this library was the lack of good options for sending rich emails with an alternative plaintext message for recipients who may be using a dated email service. I think that providing a faithful alternative message is important, and that simply using the Markdown used to generate the HTML message as the alternative is insufficient. Markdown, while fairly human-readable compared to most markup languages, still contains redundant or unhelpful syntax that is better expressed differently in plaintext. For example, escape characters should be removed, as should heading and emphasis symbols.

Features

• Renders Common Markdown messages into HTML.
• Renders a subset of Markdown into plaintext.
• Sends Markdown emails from either strings or files.

Planned Features

• Bulk mailing functionality.
• Support for rendering a greater subset of Markdown as plaintext.
• Support for attachments.

Usage

To send Markdown-formatted emails using Eärendil, use either the send_markdown_emailor send_markdown_email_from_file functions. Here is an example that uses each:

from pathlib import Path
from smtplib import SMTP

from earendil import send_markdown_email, send_markdown_email_from_file

sender_email = "[e-mail]"
password = "password"
recipient = "[e-mail]"

subject = "Example Subject"
message_path = Path("/path/to/markdown.md")
with message_path.open("r") as file:
    message = file.read()

with SMTP("smtp.gmail.com", 587) as server:
    server.starttls()
    server.login(sender_email, password)
    # Here, you can either use:
    send_markdown_email(server, sender_email, recipient, subject, message)
    # or, alternatively:
    send_markdown_email_from_file(server, sender_email, recipient, subject, message_path)
