This article provides code snippets to send email through python, the python email package is used in the code example to send an email with python.

Eend Email Python |
Getting Started
The python email module(smtplib module) defines an SMTP client (called python SMTP client) session object that can be used to send mail to any Internet machine with an SMTP or ESMTP listener daemon.
This module is a native module (inbuild with python), it does not require to install an external library to send email through python.
Send an Email with Python
The following is the python codes to send an email with plain text and not attachment.
# Sending a emails without attachments using Python.
# importing the required library(python email module).
import smtplib
# email sender python
sender = 'sender_email_id'
# Sender password
password="sender_password"
#email receiver python
receivers = ['receiver_email_id']
# message to be sent
message = "Content to be sent"
# creates python smtp server object
email = smtplib.SMTP('python smtp email:smtp_host_name', Port_Number)
# smtp login python
email.login(sender, password)
# python send email smtp
email.sendmail(sender, receivers, message)
# terminating the session
email.quit()
Python Code to Send Email
Python Send Email with Attachment
To send email via python with attachment, along with the smtplib library the following libraries need to be imported.
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
The following code constain the python script to send email with attachment. The code contains the steps how to read the attachment from local computer and attachech it with mail body.
# python send email with attachment
# importing the required library(python email module).
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
# email sender python
sender = 'sender_email_id'
# Sender password
password="sender_password"
#email receiver python
receivers = ['receiver_email_id']
# MIMEMultipart
_Mail = MIMEMultipart()
# senders email address
_Mail['From'] = sender
# receivers email address
_Mail['To'] = receivers
# the subject of mail
_Mail['Subject'] = "subject_of_the_mail"
filename = "Path of file (file_name_with_extension)"
# the body of the mail
body = "body_of_the_mail"
#The body and the attachments for the mail
_Mail.attach(MIMEText(body, 'plain'))
# Open the file as binary mode with readonly
# rb is a flag for readonly
attachment = open(filename, "rb")
# MIMEBase
payload = MIMEBase('application', 'octet-stream')
# To change the payload into encoded form
payload .set_payload((attachment).read())
# encode into base64
encoders.encode_base64(payload )
#add payload header with filename
payload .add_header('Content-Disposition', "attachment; filename= %s" % filename)
# attach the instance 'p' to instance '_Mail'
_Mail.attach(payload )
#python smtp client
# creates python smtp client object
email = smtplib.SMTP('email_host_name', email_port_number)
#enable security
email.starttls()
# smtp login python
email.login(fromaddr, password)
# Converts the Multipart _Mail into a string
message = _Mail.as_string()
# python send email smtp
email.sendmail(sender, receivers, message)
# terminating the session
email.quit()
Python Send Email
In the above code, the MIME objects are created in order to store the sender and receiver information and some other details(subject, body of mail). MIME is also needed to set the attachment with the mail.
SMTP Python Example
The following example contains python code to send mail from python using gmail SMTP server with attachment.
# python send email with attachment
# importing the required library(python email module).
import smtplib
from email.mime.multipart import MIMEMultipart
from email.mime.text import MIMEText
from email.mime.base import MIMEBase
from email import encoders
# email sender python
sender = 'kailashsblogs@gmail.com'
# Sender password
password="###########"
#email receiver python
receivers = ['kailashsblogs@hotmail.com']
# MIMEMultipart
_Mail = MIMEMultipart()
# senders email address
_Mail['From'] = sender
# receivers email address
_Mail['To'] = receivers
# the subject of mail
_Mail['Subject'] = "python send email test"
# the body of the mail
body = "Test Python Gmail Send Email"
#The body and the attachments for the mail
_Mail.attach(MIMEText(body, 'plain'))
filename = "D:\document\testfile.txt"
# Open the file as binary mode with readonly
# rb is a flag for readonly
attachment = open(filename, "rb")
# MIMEBase
payload = MIMEBase('application', 'octet-stream')
# To change the payload into encoded form
payload .set_payload((attachment).read())
# encode into base64
encoders.encode_base64(payload )
#add payload header with filename
payload .add_header('Content-Disposition', "attachment; filename= %s" % filename)
# attach the instance 'p' to instance '_Mail'
_Mail.attach(payload )
#python smtp gmail
email = smtplib.SMTP('smtp.gmail.com', 587)
#enable security
email.starttls()
# smtp login python
email.login(fromaddr, password)
# Converts the Multipart _Mail into a string
message = _Mail.as_string()
# python send email gmail
email.sendmail(sender, receivers, message)
# terminating the session
email.quit()
python smtp multiple recipients
