Python server programming: Use Mail service library to implement email push

Python is a high-level programming language that can be used to write a variety of applications and systems. Python also plays an important role in server programming. This article will introduce how to use Python's Mail service library to implement email push.

What is the Mail service library?

The Mail service library is Python's built-in email sending tool library, which provides functions for sending emails and reading emails. Mail push can be easily implemented through the Mail service library.

How to use the Mail service library to send emails?

We can use the smtplib module of the Mail service library to send emails. The SMTP class in the smtplib module provides the function of sending emails. Here is a simple example code:

import smtplib
from email.mime.text import MIMEText

sender = 'example@gmail.com'
receivers = ['receiver1@gmail.com', 'receiver2@gmail.com']

message = MIMEText('This is a test email.')
message['Subject'] = 'Test email'
message['From'] = sender
message['To'] = ', '.join(receivers)

smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
smtpObj.starttls()
smtpObj.login(sender, 'password')
smtpObj.sendmail(sender, receivers, message.as_string())
smtpObj.quit()

print("Sent email successfully")

In this example, we first specify the sender and recipient email addresses and create a MIMEText object that contains the body of the message. We also set the subject and email related properties, including sender, recipient and other related information. By using the SMTP class, we create an SMTP object and use the starttls() function to send a TLS handshake request to the Mail server with port number 587. We then use the login() function to log in to the sender's email account. Finally, we send the email to the specified recipient through the sendmail() function and close the SMTP connection using the quit() function.

How to use the Mail service library to implement email push?

Now that we have understood how to use the Mail service library to send emails, we can use these technologies to implement email push.

Suppose we have a website that needs to send email reminders to users.

We can use the Mail service library to send a welcome email when the user registers:

import smtplib
from email.mime.text import MIMEText

def send_welcome_email(user_email):
    sender = 'example@gmail.com'
    receivers = [user_email]

    message = MIMEText('Welcome to our website!')
    message['Subject'] = 'Welcome to our website'
    message['From'] = sender
    message['To'] = ', '.join(receivers)

    smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
    smtpObj.starttls()
    smtpObj.login(sender, 'password')
    smtpObj.sendmail(sender, receivers, message.as_string())
    smtpObj.quit()

if __name__ == '__main__':
    user_email = 'user1@gmail.com'
    send_welcome_email(user_email)

We can also use an email push to remind the user to reset the password:

import smtplib
from email.mime.text import MIMEText

def send_password_reset_email(user_email, reset_link):
    sender = 'example@gmail.com'
    receivers = [user_email]

    message = MIMEText('Please click the link below to reset your password:' + reset_link)
    message['Subject'] = 'Password reset'
    message['From'] = sender
    message['To'] = ', '.join(receivers)

    smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
    smtpObj.starttls()
    smtpObj.login(sender, 'password')
    smtpObj.sendmail(sender, receivers, message.as_string())
    smtpObj.quit()

if __name__ == '__main__':
    user_email = 'user1@gmail.com'
    reset_link = 'http://example.com/reset-password'
    send_password_reset_email(user_email, reset_link)

In these examples , we used the same method of sending emails, but the information we sent was different. We can use the same method to send various types of emails, such as subscription notifications, transaction updates, and other reminders.

Conclusion

Python’s Mail service library can implement email push very conveniently. Using the Mail service library, we can make the website more intelligent and implement user-friendly email prompts. Automated email sending is extremely valuable when it comes to applying it to real-life situations. This approach frees you from unnecessary tasks and takes care of your users.
