A modern and efficient Python library for sending emails with SMTP, Jinja2 templates, and attachments.
MailToolsBox is a modern, feature-rich Python package designed for sending and managing emails with ease. It provides robust functionality for handling SMTP email sending, template-based emails using Jinja2, attachments, CC/BCC support, and email validation. Additionally, MailToolsBox ensures backward compatibility with legacy implementations.
SendAgentInstall MailToolsBox from PyPI using pip:
pip install MailToolsBox
The EmailSender class is the primary interface for sending emails. Below is an example of sending a simple plain text email:
from MailToolsBox import EmailSender
# Email configuration
sender = EmailSender(
user_email="your@email.com",
server_smtp_address="smtp.example.com",
user_email_password="yourpassword",
port=587
)
# Sending email
sender.send(
recipients=["recipient@example.com"],
subject="Test Email",
message_body="Hello, this is a test email!"
)
sender.send(
recipients=["recipient@example.com"],
subject="HTML Email Example",
message_body="""<h1>Welcome!</h1><p>This is an <strong>HTML email</strong>.</p>""",
html=True,
attachments=["/path/to/document.pdf"]
)
MailToolsBox allows sending emails using Jinja2 templates stored in the templates/ directory.
templates/welcome.html):<html>
<head>
<title>Welcome</title>
</head>
<body>
<h1>Welcome, {{ username }}!</h1>
<p>Click <a href="{{ activation_link }}">here</a> to activate your account.</p>
</body>
</html>
context = {
"username": "John Doe",
"activation_link": "https://example.com/activate"
}
sender.send_template(
recipient="recipient@example.com",
subject="Welcome to Our Service",
template_name="welcome.html",
context=context
)
sender.send(
recipients=["recipient@example.com"],
subject="CC & BCC Example",
message_body="This email has CC and BCC recipients!",
cc=["cc@example.com"],
bcc=["bcc@example.com"]
)
SendAgentFor those migrating from earlier versions, SendAgent ensures seamless compatibility:
from MailToolsBox import SendAgent
legacy_sender = SendAgent(
user_email="your@email.com",
server_smtp_address="smtp.example.com",
user_email_password="yourpassword",
port=587
)
legacy_sender.send_mail(
recipient_email=["recipient@example.com"],
subject="Legacy Compatibility Test",
message_body="Testing backward compatibility."
)
Example using environment variables:
import os
sender = EmailSender(
user_email=os.getenv("EMAIL"),
server_smtp_address=os.getenv("SMTP_SERVER"),
user_email_password=os.getenv("EMAIL_PASSWORD"),
port=int(os.getenv("SMTP_PORT", 587))
)
MailToolsBox provides built-in logging to help debug issues:
import logging
logging.basicConfig(level=logging.INFO)
Example of handling exceptions:
try:
sender.send(
recipients=["recipient@example.com"],
subject="Error Handling Test",
message_body="This is a test email."
)
except Exception as e:
print(f"Failed to send email: {e}")
