Python Send E-mails

Python Send E-mails is a script that lets you send automatic E-Mails with Python and the SMTP library.

Warning

If you get an error while running the script it's because of a bug I can't seem to fix yet. I welcome you to test the app and try to solv the bug. If you solved it, please open a Pull Request with the solved main.py script. For more details check the comments of the Tkinter GUI Pull Request.

Installation

Python should come pre-installed with smtplib which is a required library for this project. If not, a pip install smtplib should work.

Usage

# Importing the SMTP library which handles sending E-mails and routing E-mails between mail servers.
import smtplib
  
#Establish SMTP Connection
s = smtplib.SMTP('smtp.gmail.com', 587) 
  
#Start TLS based SMTP Session
s.starttls() 

# Importing the SMTP library which handles sending E-mails and routing E-mails between mail servers.
import smtplib
from tkinter import *



# create root window 
root = Tk() 
  
# root window title and dimension 
root.title("Python Send E-mails") 
root.geometry('350x200') 

#Establish SMTP Connection
s = smtplib.SMTP('smtp.gmail.com', 587)

#Start TLS based SMTP Session
s.starttls() 

# adding the Sender E-mail label to the root window 
lbl_1 = Label(root, text = "Sender E-mail address: ") 
lbl_1.grid() 

# adding Entry Field 
sender_e_mail_address = Entry(root, width=30) 
sender_e_mail_address.grid(column = 1, row =0) 

# adding the Sender E-mail label to the root window 
lbl_2 = Label(root, text = "Receiver E-mail address: ") 
lbl_2.grid() 

# adding Entry Field 
receiver_e_mail_address = Entry(root, width=30) 
receiver_e_mail_address.grid(column = 1, row =1) 
  
# function to display text when 
# button is clicked 
def clicked(): 
    #Login Using Your E-mail & Password
    s.login(sender_e_mail_address, "<sender-E-mail-password")

    #Email Body Content
    message = """
    Hello, this is an example message!
    """

    #To Send the E-mail
    s.sendmail(sender_e_mail_address, receiver_e_mail_address, message)
    
    #Terminating the SMTP Session
    s.quit()

    
# button widget with text inside 
btn = Button(root, text = "Send" , 
             fg = "black", command=clicked) 
  
btn.grid(column=1, row=3) 


root.mainloop()

IMPORTANT : If you're using Gmail you might need to allow less secure apps from your account settings. When you try the script for the first time you might also need to go to your sender address and say that it was you to who ran the script to stop Google's warning that the program might not be secure.
