Tutorial: Sending an Email using Python

In this tutorial, we’ll learn how to send emails, including attachments, using Python.

Table of Contents:

  • Setting Up
  • Crafting the Email
  • Sending the Email
  • Using Gmail as the SMTP Server

Setting Up

Before we begin, we need to set up the email configurations:

import smtplib
from email.message import EmailMessage
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
from email.mime.base import MIMEBase
from email import encoders# Email configurations
SMTP_SERVER = 'smtp.your-email-provider.com'
SMTP_PORT = 587  # Common ports: 587 for TLS, 465 for SSL, 25 for non-secure
SENDER_EMAIL = 'your-email@example.com'
SENDER_PASSWORD = 'your-email-password'
RECEIVER_EMAIL = 'receiver-email@example.com'

Replace the placeholders with your actual email configurations.


Crafting the Email

  1. Creating a Basic Email:
msg = EmailMessage()
msg['From'] = SENDER_EMAIL
msg['To'] = RECEIVER_EMAIL
msg['Subject'] = 'Your Subject Here'
msg.set_content('Your email body text here.')
  1. Adding Attachments:

If you want to attach a file, use the following code:

filename = 'path-to-your-file.txt'
with open(filename, 'rb') as attachment:file_data = attachment.read()file_type = mimetypes.guess_type(filename)[0]file_name = os.path.basename(filename)msg.add_attachment(file_data, maintype='application', subtype='octet-stream', filename=file_name)

Sending the Email

Now that our email is ready, let’s send it:

with smtplib.SMTP(SMTP_SERVER, SMTP_PORT) as server:server.starttls()  # Upgrade the connection to secure encrypted SSL/TLSserver.login(SENDER_EMAIL, SENDER_PASSWORD)server.send_message(msg)

Using Gmail as the SMTP Server

If you’re using Gmail as your email provider, there are a couple of additional considerations:

  • SMTP Settings for Gmail:
SMTP_SERVER = 'smtp.gmail.com'
SMTP_PORT = 587  # Use 465 for SSL
  • Less Secure Apps:

For Gmail to allow third-party apps and scripts to send emails, you might need to enable “Less Secure Apps” in your Gmail settings. To enable:

  1. Go to Google Account.
  2. Click on “Security” on the left-hand side.
  3. Scroll down to the “Less secure app access” section.
  4. Toggle the switch to ON.

Note: Always turn off “Less Secure Apps” after you’re done to ensure your account’s security.


Conclusion

Sending emails via Python is straightforward and powerful, especially when integrating into automation tasks, notifications, or reporting systems. Always ensure you’re following best security practices, especially when handling email credentials.
