emails 1.1.2

Modern python library for emails.

Build, transform, and send emails in Python with a high-level API.

python-emails helps you compose HTML and plain-text messages, attach files, embed inline images, render templates, apply HTML transformations, sign with DKIM, and send through SMTP without hand-building MIME trees.

Why python-emails

• A concise API over email and smtplib

• HTML and plain-text messages in one object

• File attachments and inline images

• CSS inlining, image embedding, and HTML cleanup

• Jinja2, Mako, and string template support

• DKIM signing

• Loaders for URLs, HTML files, directories, ZIP archives, and RFC 822 messages

• SMTP sending with SSL/TLS support

• Async sending via aiosmtplib

Quick Example

import emails

message = emails.html(
    subject="Your receipt",
    html="<p>Hello!</p><p>Your payment was received.</p>",
    mail_from=("Billing", "[e-mail]"),
)
message.attach(filename="receipt.pdf", data=open("receipt.pdf", "rb"))

response = message.send(
    to="[e-mail]",
    smtp={
        "host": "smtp.example.com",
        "port": 587,
        "tls": True,
        "user": "[e-mail]",
        "password": "app-password",
    },
)
assert response.status_code == 250

What You Get

• Message composition for HTML, plain text, headers, CC/BCC, and Reply-To

When To Use It

Use python-emails when you need more than a minimal plain-text SMTP call: HTML emails, attachments, inline images, template rendering, DKIM, message loading from external sources, or a cleaner API than hand-written email.mime code.

If you only need to send a very small plain-text message and want zero dependencies, the standard library may be enough.
