Sending Email From Python Using Command Line

January 10, 2014

Since many of my commenters ask for something a little more advance in Python, I wrote up this script I wrote. Notice that this script will allow you to use almost anything you would come to except from an email client. Sending Email From Python is simpler than you think. That includes cc and bcc fields, html mode and attachment files. You will have to use your own email configuration, I left the settings from gmail, but any email account could be used. Just fill in your user name and password. You can include this module and use the compose_email() function to send emails directly from you Python program. As a word of advice, try to not send too many emails all at once (like 400 emails). Gmail will not send the emails and your email address will be marked as spam. Use with caution.

NOTE: The only output of the program is a single print statement (assuming it all went well), that will indicate an email has been sent.

#account setup
username = '***';
password = '***';
server = '';

from time import sleep;
import smtplib;
from email.mime.application import MIMEApplication
from email.mime.text import MIMEText;
from email.mime.multipart import MIMEMultipart;

# create msg - MIME* object
# takes addresses to, from cc and a subject
# returns the MIME* object
def create_msg(to_address,

    msg = MIMEMultipart();
    msg['Subject'] = subject;
    msg['To'] = to_address;
    msg['Cc'] = cc_address;
    msg['From'] = from_address;
    return msg;

# send an email
# takes an smtp address, user name, password and MIME* object
# if mode = 0 sends to and cc
# if mode = 1 sends to bcc
def send_email(smtp_address, usr, password, msg, mode):
    server = smtplib.SMTP(smtp_address);
    if (mode == 0 and msg['To'] != ''):
        server.sendmail(msg['From'],(msg['To']+msg['Cc']).split(","), msg.as_string());
    elif (mode == 1 and msg['Bcc'] != ''):
    elif (mode != 0 and mode != 1):
        print 'error in send mail bcc'; print 'email cancled'; exit();

# compose email
# takes all the details for an email and sends it
# address format: list, [0] - to
#                       [1] - cc
#                       [2] - bcc
# subject format: string
# body format: list of pairs [0] - text
#                            [1] - type:
#                                        0 - plain
#                                        1 - html
# files is list of strings
def compose_email(addresses, subject, body, files):

    # addresses
    to_address = addresses[0];
    cc_address = addresses[1];
    bcc_address = addresses[2];

    # create a message
    msg = create_msg(to_address, cc_address=cc_address , subject=subject);

    # add text
    for text in body:
        attach_text(msg, text[0], text[1]);

    # add files
    if (files != ''):
        file_list = files.split(',');
        for afile in file_list:
            attach_file(msg, afile);

    # send message
    send_email(server, username, password, msg, 0);

    # check for bcc
    if (bcc_address != ''):
        msg['Bcc'] = bcc_address;
        send_email(server, username, password, msg, 1);

    print 'email sent'

# attach text
# attaches a plain text or html text to a message
def attach_text(msg, atext, mode):
    part = MIMEText(atext, get_mode(mode));

# util function to get mode type
def get_mode(mode):
    if (mode == 0):
        mode = 'plain';
    elif (mode == 1):
        mode = 'html';
        print 'error in text kind'; print 'email cancled'; exit();
    return mode;

# attach file
# takes the message and a file name and attaches the file to the message
def attach_file(msg, afile):
    part = MIMEApplication(open(afile, "rb").read());
    part.add_header('Content-Disposition', 'attachment', filename=afile);

#to be tested...
              'test v.5.0',
              [['some text goes here...\n',0]],

#compose_email can take the following arguments:
#	1. to recipients (separated by a comma)
#	2. cc recipients (separated by a comma)
#	3. bcc recipients (separated by a comma)
#	4. subject
#	5. a list with message and mode (plain txt or html)
#	6. files to be attached
