Email multiple contacts in Python

Question

I am trying to send an email to multiple addresses. The code below shows what I'm attempting to achieve. When I add two addresses the email does not send to the second address. The code is:

 me = '[email protected]'
 you = '[email protected], [email protected]'
 msg['Subject'] = "Some Subject"
 msg['From'] = me
 msg['To'] = you
 # Send the message via our own SMTP server
 s = smtplib.SMTP('a.a.a.a')
 s.sendmail(me, [you], msg.as_string())
 s.quit()

I have tried:

you = ['[email protected]', '[email protected]']

and

you = '[email protected]', '[email protected]'

Thanks

• Karmic Coder: have you tried '[email protected]; [email protected]' ?

Answer 1

You want this:

from email.utils import COMMASPACE
...
you = ["[email protected]", "[email protected]"]
...
msg['To'] = COMMASPACE.join(you)
...
s.sendmail(me, you, msg.as_string())

Answer 2

Try

s.sendmail(me, you.split(","), msg.as_string())

If you do you = ['[email protected]', '[email protected]']

Try

msg['To'] = ",".join(you)
...
s.sendmail(me, you, msg.as_string())

Answer 3

you = ('one@address', 'another@address')
s.sendmail(me, you, msg.as_string())

Answer 4

import smtplib
from email.mime.text import MIMEText
s = smtplib.SMTP('smtp.foobar.com')
msg = MIMEText("""body""")
sender = '[email protected]'
recipients = ['[email protected]', '[email protected]']
msg['Subject'] = "subject line"
msg['From'] = sender
msg['To'] = ", ".join(recipients)
s.sendmail(sender, recipients, msg.as_string())

In the example to read emails from the configuration file, for example configparser - pip install configparser.

• In the created config.ini file we add the code from below:

[mail]
SENDER = [email protected]
RECEIVERS = [email protected],[email protected]

• Create another test.py file located in the same directory

import configparser
import smtplib
from smtplib import SMTPException
config = configparser.RawConfigParser() 
config.read('config.ini')
# template
msg = """From: From Person <{0}>
To:{1}
MIME-Version: 1.0
Content-type: text/html
Subject: Hello {2}
Check your results :)
{3}
"""
# universal function that would send mail when called
def send_mail(sender, receivers, subject, message):
 try:
 session = smtplib.SMTP(host = "ip", port = 25)
 session.ehlo()
 session.starttls()
 session.ehlo()
 session.sendmail(sender, receivers, msg.format(sender, receivers, subject, message)) 
 session.quit()
 print("Your mail has been sent successfuly! Thank you for your feedback!")
 except SMTPException:
 print("Error: Unable to send email.")
# html context for email
your_subject = "SMTP HTML e-mail test"
your_message = """This is an e-mail message to be sent in HTML format
<b>This is HTML message.</b>
<h1>This is headline.</h1>
"""
# The call to the universal e-mail function to which we pass the parameters in this example are given above
def setup_and_send_mail():
 send_mail(config.get('mail', 'SENDER'), (config.get('mail', 'RECEIVERS')), your_subject, your_message) 
if __name__ == "__main__":
