Automating Daily Email Reports in Python: A Step-by-Step Guide

In today’s fast-paced world, automating repetitive tasks can save a significant amount of time and effort. One such task is sending daily email reports. In this article, I’ll walk you through how to automate sending daily email reports using Python. I’ll cover everything from setting up your environment to scheduling the script to run daily.

Step 1: Setting Up Your Environment

Before we dive into the code, let’s make sure your environment is ready. You’ll need Python installed on your machine along with a few additional libraries. If you don’t have Python installed, download and install it from python.org.

Next, open your terminal or command prompt and install the necessary libraries by running:

Step 2: Writing the Email Sending Script

Now that your environment is set up, we can start writing our script. We’ll use the smtplib library to send emails and the email library to construct our email content.

Step 3: Understanding the Script

Let’s break down what each part of the script does:

1. Email Configuration: We set up the SMTP server, port, sender’s email, receiver’s email, and the sender’s email password.
2. Create Email Content: Using MIMEMultipart and MIMEText, we create the structure and body of the email.
3. Send Email: We establish a secure session with the SMTP server, log in using the sender’s credentials, and send the email.
4. Schedule the Task: Using the schedule library, we set the script to run the send_email function every day at 9:00 AM.
5. Keep the Script Running: The while True loop ensures that the script continues running, checking every minute to see if it’s time to send the email.

Step 4: Scheduling the Script to Run Daily

To ensure that your script runs daily without manual intervention, you need to schedule it as a background task. Here’s how you can do it on different operating systems:

On Windows

1. Open Task Scheduler and create a new task.
2. Set the trigger to "Daily" and choose your preferred time.
3. Set the action to "Start a Program" and point it to the Python executable, passing the path to your script as an argument.

On macOS and Linux

You can use cron to schedule your script:

1. Open your terminal.
2. Run crontab -e to edit your cron jobs.
3. Add the following line to schedule your script to run daily at 9:00 AM:

Conclusion
