Python Mailable

Python Mailable is an email builder for Python, inspired by Laravel's Mailable class. It provides a clean and reusable structure for defining, composing, and sending emails with rich context and templates.

Important

We currently only support rendering emails, not sending them.

This package helps you build and render email content using templates, but you need to handle email sending yourself with your own SMTP client or email delivery service.

Use the .render() method to get your email body, and then integrate with any mail-sending solution you prefer.

Features

• Define email classes with subjects, recipients, and templates
• Pass context to templates for dynamic rendering
• Attach files easily
• Designed for clarity, testability, and reusability

Usage

Creating a Mailable

To define a custom email, subclass Mailable and implement the build() method. Use the fluent API to configure the mail.

from dataclasses import dataclass
from mailable import Mailable

@dataclass
class OrderShipped(Mailable):
    user: User  # Your domain model or DTO

    def build(self):
        return (
            self.to(self.user.email)
                .subject("Your order has shipped!")
                .template("emails/order_shipped.html")
                .with_context({"user": self.user})
        )

Sending the email

user = User(email="jane.doe@example.com", name="Jane Doe")

email = OrderShipped(user).build()
email.send()  # Sends using the built-in SMTP backend

💡 Want to use your own mail client instead?
You can call email.render() to get the subject, body, and recipient info — and pass that into your own delivery system.
