Send Email Using Python

Send Email using Python has many benefits that can make your communication easier and improve your workflow. Automating daily email reports in Python can be done using the smtplib library for sending emails and email library to construct the email content. Below is a step-by-step guide on how to set it up:

Step 1: Install Required Libraries

First, ensure you have the necessary libraries. You might need to install the following:

pip install smtplib email

Step 2: Set Up Your Email Credentials

Store your email credentials securely. For simplicity, we’ll use environment variables here:

Styled Text Area
import os

# Set environment variables (do this in your OS or securely within your script)
os.environ['EMAIL_USER'] = 'your_email@example.com'
os.environ['EMAIL_PASS'] = 'your_email_password'

Step 3: Create the Email Content

Now we will construct the email content using the email.mime library:

Styled Text Area
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.application import MIMEApplication
def create_email(subject, body, to_email, from_email, attachment_path=None):
msg = MIMEMultipart()
msg['From'] = from_email
msg['To'] = to_email
msg['Subject'] = subject
# Attach the body with the msg instance
msg.attach(MIMEText(body, 'plain'))
# Attach any file if provided
if attachment_path:
with open(attachment_path, "rb") as attachment:
part = MIMEApplication(attachment.read(), Name=attachment_path)
part['Content-Disposition'] = f'attachment; filename="{attachment_path}"'
msg.attach(part) return msg

Step 4: Send Email Using Python

We will use the smtplib library, send the email:

Styled Text Area
import smtplib

def send_email(subject, body, to_email, attachment_path=None):
from_email = os.getenv('EMAIL_USER')
password = os.getenv('EMAIL_PASS')

# Create the email
msg = create_email(subject, body, to_email, from_email, attachment_path)
# Send the email
try:
with smtplib.SMTP('smtp.example.com', 587) as server: # Use your email provider's SMTP server
server.starttls()
server.login(from_email, password)
server.send_message(msg)
print(f'Email sent to {to_email}')
except Exception as e: print(f'Failed to send email: {e}')

Step 5: Automate the Script to Run Daily

You can use a task scheduler to run the (send email using python) script daily. Here are examples for different operating systems:

On Windows (Using Task Scheduler)

  1. Open Task Scheduler and create a new basic task.
  2. Set the trigger to daily.
  3. Set the action to start a program.
  4. Browse to your Python executable and add the script path as an argument.

How to Use This Script

Here’s a simple step-by-step process:

  1. Set Environment Variables:

    • Store your email username and password in EMAIL_USER and EMAIL_PASS.
  2. Configure SMTP Server:

    • Update smtp.example.com and 587 to your email provider’s server and port.
  3. Run the Script:

    • Execute the script with the subject, body, recipient email, and attachment path (if needed).

With these steps, you can easily send daily email reports without any manual effort. 

Use Case Examples

Sending Emails with Python:

  1. Software Developers Developers can use Python scripts to automate routine notifications, such as deployment updates or code review reminders, ensuring timely communication without manual intervention.

  2. IT Administrators IT admins can automate system alerts and status updates via email, reducing the need for constant monitoring and allowing for quicker responses to system issues.

  3. Office Workers Office staff can use email automation to send out daily reports, meeting reminders, or scheduled announcements, improving efficiency and ensuring timely dissemination of information.

  4. Sales Teams Sales professionals can automate follow-up emails to clients and prospects, ensuring consistent communication and freeing up time to focus on high-priority tasks.

  5. Educational Institutions Teachers and administrators can automate the distribution of newsletters, grade reports, and event reminders to students and parents, ensuring consistent and timely communication.
