Email Automation System

Abstract

Email Automation System is a Python project that automates email sending and management. The application features scheduling, templates, and a CLI interface, demonstrating best practices in productivity and communication.

Prerequisites

• Python 3.8 or above
• A code editor or IDE
• Basic understanding of email protocols
• Required libraries: smtplib, email, schedule

Before you Start

Install Python and the required libraries:

Install dependencies

pip install schedule

Getting Started

Create a Project

1. Create a folder named email-automation-system.
2. Open the folder in your code editor or IDE.
3. Create a file named email_automation_system.py.
4. Copy the code below into your file.

Write the Code

Email Automation System

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

class EmailAutomationSystem:
    def __init__(self, smtp_server, port, username, password):
        self.smtp_server = smtp_server
        self.port = port
        self.username = username
        self.password = password

    def send_email(self, to_email, subject, body):
        msg = MIMEMultipart()
        msg['From'] = self.username
        msg['To'] = to_email
        msg['Subject'] = subject
        msg.attach(MIMEText(body, 'plain'))
        with smtplib.SMTP(self.smtp_server, self.port) as server:
            server.starttls()
            server.login(self.username, self.password)
            server.sendmail(self.username, to_email, msg.as_string())
        print(f"Email sent to {to_email}")

if __name__ == "__main__":
    print("Email Automation System Demo")
    # system = EmailAutomationSystem('smtp.example.com', 587, 'user@example.com', 'password')
    # system.send_email('recipient@example.com', 'Test Subject', 'Hello from Python!')

Example Usage

Run email automation

python email_automation_system.py

What it produces

Running the file exactly as it ships takes 0.2 s and prints:

python email_automation_system.py

How it fits together

Read from the top: this is what runs when you execute the file, and which function calls which. It is generated from the code, so it cannot drift from it.

Explanation

Key Features

• Email Sending: Automates sending emails.
• Scheduling: Schedules emails for future delivery.
• Templates: Uses email templates for consistency.
• Error Handling: Validates inputs and manages exceptions.
• CLI Interface: Interactive command-line usage.

Code Breakdown

1. What it imports (lines 1–3)

email_automation_system.py

import smtplib
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart

2. EmailAutomationSystem — the class (lines 5–22)

email_automation_system.py

class EmailAutomationSystem:
    def __init__(self, smtp_server, port, username, password):
        self.smtp_server = smtp_server
        self.port = port
        self.username = username
        self.password = password
 
    def send_email(self, to_email, subject, body):
        msg = MIMEMultipart()
        msg['From'] = self.username
        msg['To'] = to_email
        msg['Subject'] = subject
        msg.attach(MIMEText(body, 'plain'))
        with smtplib.SMTP(self.smtp_server, self.port) as server:
            server.starttls()
            server.login(self.username, self.password)
            server.sendmail(self.username, to_email, msg.as_string())
        print(f"Email sent to {to_email}")
