How to Send Emails using Python

By reading this article, you’ll learn the basic steps required to send a simple email in Python. We’ll be using a built-in module called smtplib. This means there will be no additional setup or installation required. Based on the official documentation, this module:

There are three sections in this tutorial

  1. Flask server
  2. Implementation
  3. Conclusion

Let’s proceed to the next section to set up the Flask server.

1. Flask Server

It’s highly recommended to set up a virtual environment before you proceed. Activate your virtual environment, and install Flask via the following code:

pip install flask

Create a Python file, and add in the following code to create a simple server. I will be naming it test.py.

from flask import Flask, request, jsonify

app = Flask(__name__)

@app.route('/')
def hello_world():
    return "Hello world!"
    
if __name__ == "__main__":
    app.run('0.0.0.0',port=5000)

Save the file, and run it with the following code. Replace the name of the file accordingly. I’m using test.py for this tutorial.

python test.py

Open up a browser, and access it based on the IP of your machine. You can open up a command line and type ipconfig to identify the address of your machine. You should be able to see the following output.

Proceed to the next section, and start playing around with the smtplib module.

2. Implementation

SMTP Object

First and foremost, add the following import declaration on top of the Python file.

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

email.mime module is required to craft the email messages. It’s part of the legacy module that’s still quite useful. Feel free to use other modules if you intend to create complex email messages.

The SMTP objects accept two input parameters:

  • server name
  • port

Please be noted that I’m using Outlook as the SMTP server, and the connection is based on TLS. In fact, you can use your own SMTP server or third-party services such as Gmail or Outlook. You have to modify the parameters based on the setting of the SMTP server you’re going to use. You have to allow your email to be accessible by third-party services. The setting for Outlook is as follows. Modify them accordingly if you’re using another SMTP server.

Create a SMTP object with the following code. Replace smtp.office365.com with the server name of your SMTP server.

smtpObj = smtplib.SMTP('smtp.office365.com', 587)

Continue by appending the following code to start the authentication:

smtpObj.ehlo()
smtpObj.starttls()
smtpObj.login("sender@email.com", "password")

MIME

The next step is to create the email messages. Let’s create a function called send_test_mail and define the sender and receiver emails. You can use your own email as both the sender and receiver to test it out. I’ve added an additional string input called body. It’ll be the main content that we’ll be sending over in the email.

def send_test_mail(body):
    sender_email = "sender@email.com"
    receiver_email = "receiver@email.com"

Inside the function, create a MIMEMultipart object that’ll be responsible for storing all the MIMEText and MIMEImage objects.

msg = MIMEMultipart()
msg['Subject'] = '[Email Test]'
msg['From'] = sender_email
msg['To'] = receiver_email

Next, create the MIMEText object using the input parameter we defined earlier. We’ll format it inside an HTML string. Attach it to the MIMEMultipart object.

msgText = MIMEText('<b>%s</b>' % (body), 'html')
msg.attach(msgText)

The last step is to call the sendemail function. It’s recommended to wrap it inside a try catch block.

try:
    smtpObj.sendmail(sender_email, receiver_email, msg.as_string())
except Exception as e:
    print(e)

In order to test it, you need to make a call to the send_test_mail function. The easiest way is to do it inside the main function. Feel free to change the input text.

if __name__ == "__main__":
    send_test_mail("Welcome to Medium!")
    app.run('0.0.0.0',port=5000)

Run the server, and you should see the following email inside your mailbox.

This is image title

Text attachment

You can easily add an attachment such as a CSV or TXT file to the email message via the following code. Simply assign the proper path, and open it inside a MIMEText.

filename = "example.txt"
msg.attach(MIMEText(open(filename).read()))

You should be able to get the following result.

This is image title

Image attachment

For image attachments, you have to use the MIMEImage object instead. You can change the name of the attachment by adding a header Content-Disposition to it.

with open('example.jpg', 'rb') as fp:
    img = MIMEImage(fp.read())
    img.add_header('Content-Disposition', 'attachment', filename="example.jpg")
    msg.attach(img)

You should get the following result once you run the server.

This is image title

Feel free to check out the complete code in the following link.

from flask import Flask, request, jsonify
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.image import MIMEImage

smtpObj = smtplib.SMTP('smtp.office365.com', 587)
smtpObj.ehlo()
smtpObj.starttls()
smtpObj.login("sender@email.com", "password")

app = Flask(__name__)

def send_test_mail(body):
    sender_email = "sender@email.com"
    receiver_email = "receiver@email.com"

    msg = MIMEMultipart()
    msg['Subject'] = '[Email Test]'
    msg['From'] = sender_email
    msg['To'] = receiver_email

    msgText = MIMEText('<b>%s</b>' % (body), 'html')
    msg.attach(msgText)

    filename = "example.txt"
    msg.attach(MIMEText(open(filename).read()))

    with open('example.jpg', 'rb') as fp:
        img = MIMEImage(fp.read())
        img.add_header('Content-Disposition', 'attachment', filename="example.jpg")
        msg.attach(img)

    try:
        smtpObj.sendmail(sender_email, receiver_email, msg.as_string())
    except Exception as e:
        print(e)
        
@app.route('/')
def hello_world():
    return "Hello world!"

if __name__ == "__main__":
    send_test_mail("Welcome to Medium!")
    app.run('0.0.0.0',port=5000)

3. Conclusion

Let’s recap what we’ve learned today. We started off with a simple installation of a Flask server.

Then, we proceed with initializing the SMTP object, which is responsible for authentication and allows us to log into our own email.

After that, we crafted the email messages using MIMEText and MIMEImage. This allows us to send attachments in the form of text files and images.

Thanks for reading!

How To Compare Tesla and Ford Company By Using Magic Methods in Python

Magic Methods are the special methods which gives us the ability to access built in syntactical features such as ‘<’, ‘>’, ‘==’, ‘+’ etc…

You must have worked with such methods without knowing them to be as magic methods. Magic methods can be identified with their names which start with __ and ends with __ like init, call, str etc. These methods are also called Dunder Methods, because of their name starting and ending with Double Underscore (Dunder).

Now there are a number of such special methods, which you might have come across too, in Python. We will just be taking an example of a few of them to understand how they work and how we can use them.

1. init

class AnyClass:
    def __init__():
        print("Init called on its own")
obj = AnyClass()

The first example is _init, _and as the name suggests, it is used for initializing objects. Init method is called on its own, ie. whenever an object is created for the class, the init method is called on its own.

The output of the above code will be given below. Note how we did not call the init method and it got invoked as we created an object for class AnyClass.

Init called on its own

2. add

Let’s move to some other example, add gives us the ability to access the built in syntax feature of the character +. Let’s see how,

class AnyClass:
    def __init__(self, var):
        self.some_var = var
    def __add__(self, other_obj):
        print("Calling the add method")
        return self.some_var + other_obj.some_var
obj1 = AnyClass(5)
obj2 = AnyClass(6)
obj1 + obj2
