Why Use Python for Sending Emails?

Python is renowned for its simplicity and readability, making it an ideal programming language for both beginners and seasoned developers. By utilizing Python for email automation, you can:

Prerequisites for Sending Emails with Python

Before diving into the coding part, ensure you meet the following prerequisites:

  • Python Environment: Make sure you have Python installed on your device. You can download it here.
  • Email Account with SMTP Access: You will need an email provider that supports SMTP (like Gmail, Outlook, etc.).

Steps to Send Emails with Python

Step 1: Import the `smtplib` Library

The core library responsible for sending emails is smtplib, which is part of Python’s standard library.

Step 2: Establish an SMTP Connection

Create a connection with the SMTP server, specifically for Gmail:

import smtplib

# Set up the server details
smtp_server = "smtp.gmail.com"
port = 587  # For starttls

Create an SMTP object using these details:

server = smtplib.SMTP(smtp_server, port)
server.starttls()  # Secure the connection

Step 3: Authenticate

Use your email and password to log in:

sender_email = "[email protected]"
password = input("Enter your password: ")
server.login(sender_email, password)

Note: For Gmail accounts with 2-Step Verification, create an App Password instead of using your account password.

Step 4: Compose the Email

You can format the email in two ways: as plain text or HTML.

Plain Text Email Composition
receiver_email = "[email protected]"
message = """Subject: Test Email

Hello, this is a test email sent from Python."""
HTML Email Composition
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText

message = MIMEMultipart()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = "Test HTML Email"

html_content = """

  
    
Hi,

    This is a test HTML email sent using Python.

  

"""
message.attach(MIMEText(html_content, "html"))

Step 5: Send the Email

server.sendmail(sender_email, receiver_email, message.as_string())
print("Email sent successfully!")

Step 6: Close the SMTP Connection

server.quit()

Complete Example Code

Sending a Plain Text Email

import smtplib

# SMTP server information
smtp_server = "smtp.gmail.com"
port = 587
sender_email = "[email protected]"
receiver_email = "[email protected]"
password = input("Enter your password: ")

message = """Subject: Test Email

Hello, this is a test email sent from Python."""

# Create a secure SSL context
with smtplib.SMTP(smtp_server, port) as server:
    server.starttls()  # Secure the connection
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, message)

print("Email sent successfully!")

Sending an HTML Email

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

# SMTP server information
smtp_server = "smtp.gmail.com"
port = 587
sender_email = "[email protected]"
receiver_email = "[email protected]"
password = input("Enter your password: ")

# Create the email
message = MIMEMultipart()
message["From"] = sender_email
message["To"] = receiver_email
message["Subject"] = "Test HTML Email"

html_content = """

  
    
Hi,

    This is a test HTML email sent using Python.

  

"""
message.attach(MIMEText(html_content, "html"))

# Send the email
with smtplib.SMTP(smtp_server, port) as server:
    server.starttls()
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, message.as_string())

print("HTML Email sent successfully!")

Sending Emails to Multiple Recipients

To send emails to multiple recipients, you can iterate through a list:

emails = ["[email protected]", "[email protected]", "[email protected]"]

for receiver_email in emails:
    server.sendmail(sender_email, receiver_email, message.as_string())

Additional Tools and Services

For more advanced email functionalities, consider using:

  • Yagmail: Simplifies sending emails for Gmail users.
  • Mailtrap: Test email sends without using real recipients.

Practical Takeaways

To conclude, here are some practical takeaways:

  • Secure Your Credentials: Never hard-code credentials; use environment variables instead.
  • Test Your Emails: Utilize platforms like Mailtrap for testing.
  • Check Email Delivery: Be aware of sending limitations to avoid being flagged as spam.
  • Explore Libraries: Look into third-party libraries for added functionality.
