SMTP: Simple Mail Transfer Protocol


SMTP (Simple Mail Transfer Protocol) is a standardized protocol that ensures efficient and reliable transfer of email messages between different email servers. It defines the rules and procedures by which an email server sends a message to the recipient’s server.

Use case:

One use case for the SMTP protocol is in a business transaction between a supplier and a customer. After completing an order, the supplier can use the SMTP protocol to send a confirmation email to the customer, providing details about the order, delivery terms, or other relevant information. This email communication facilitates quick and efficient interaction between the supplier and the customer.

Example of script code:

import smtplib

# Set up the SMTP server details
smtp_server = ‘’
smtp_port = 587
smtp_username = ‘your_username’
smtp_password = ‘your_password’

# Compose the email
sender = ‘’
receiver = ‘’
subject = ‘Sample Email
body = ‘This is a sample email message.’

message = f”Subject: {subject}\n\n{body}”

# Connect to the SMTP server
with smtplib.SMTP(smtp_server, smtp_port) as server:
# Start the TLS encryption

# Log in to the SMTP server
server.login(smtp_username, smtp_password)

# Send the email
server.sendmail(sender, receiver, message)

print(“Email sent successfully!”)

Best practices:

  1. Ensure that you have the correct SMTP server details, including the server address, port number, and authentication credentials.
  2. Compose the email message properly, including the subject, body, and any necessary attachments.
  3. Follow proper email formatting and etiquette, including clear and concise subject lines and well-structured content.
  4. Consider using secure connections, such as TLS encryption, to protect the confidentiality and integrity of the email communication.
