How to send mail with Python

I am trying to send a simple mail with python

import smtplib

server = smtplib.SMTP('smtp.gmail.com', 587)
server.ehlo()
server.starttls()
server.login("[email protected]", "mypassword")

msg = "Hello world"
server.sendmail("[email protected]", "[email protected]", msg)
server.quit()

But I get this err:

server.login("[email protected]", "psw")

File "C:\Python\lib\smtplib.py", line 652, in login

raise SMTPAuthenticationError(code, resp)

smtplib.SMTPAuthenticationError: (534, b'5.7.14 <https://accounts.google.com/ContinueSignIn?sarp=1&scc=1&plt=AKgnsbuxb\n5.7.14 4i2u8qU8V3jgf6uGv8da1RAGPJyctRvIFy_kjai6aKVx_B6qVhoz_dzFpvfPC18H-jeM6K\n5.7.14 cnm2HVuq-wr-uw59hD31ms-cxMmnZuq6Z3_liDaDmu8_UqaiUwR4FUiuX2i5pPdQjJzFvv\n5.7.14 4VrEF5XT4ol2iN17gnB_jITpwzsjH9Ox3NCNcfl7SriHr5m7esc15PWI0CG_2CTlyh7RxW\n5.7.14 XhoJPajs8GMd-khOQWUqucywfrfo> Please log in via your web browser and\n5.7.14 then try again.\n5.7.14 Learn more at\n5.7.14 https://support.google.com/mail/bin/answer.py?answer=78754 ef10sm13614207wjd.49 - gsmtp')

Yea, like the answer posted, it was a matter of authentication :)

I'd like to further help you with sending emails by advising the yagmail package (I'm the maintainer, sorry for the advertising, but I feel it can really help!). Note that I'm also maintaining a list of common errors there, such as the authentication error.

The whole code for you would be:

import yagmail
yag = yagmail.SMTP('user', 'pw')
yag.send(contents = msg)

Note that I provide defaults for all arguments, for example if you want to send to yourself, you can omit "to = [email protected]", if you don't want a subject, you can omit it also.

Furthermore, the goal is also to make it really easy to attach html code or images (and other files).

Where you put contents you can do something like:

contents = ['Body text, and here is an embedded image:', 'http://somedomain/image.png',
            'You can also find an audio file attached.', '/local/path/song.mp3']

Wow, how easy it is to send attachments! This would take like 20 lines without yagmail ;)

Also, if you set it up once, you'll never have to enter the password again (and have it safely stored). In your case you can do something like:

import yagmail
yagmail.SMTP().send(contents = contents)

which is much more concise!

I'd invite you to have a look at the github or install it directly with pip install yagmail.

You could use a free mail API such as mailgun:

import requests

def send_simple_message(target):
    return requests.post(
        "https://api.mailgun.net/v3/samples.mailgun.org/messages",
        auth=("api", "key-3ax6xnjp29jd6fds4gc373sgvjxteol0"),
        data={"from": "Excited User <[email protected]>",
              "to": [target],
              "subject": "Hello",
              "text": "Testing some Mailgun awesomeness!"})

send_simple_message('[email protected]')

Using an API like this avoids the issue of individual account authentication all together.

you can use this code:

import smtplib

session = smtplib.SMTP('smtp.gmail.com', 587)
session.ehlo()
session.starttls()
session.login('[email protected]',' password')
headers = "\r\n".join(["from: " + '[email protected]',
                       "subject: " + "test",
                       "to: " + '[email protected]',
                       "mime-version: 1.0",
                       "content-type: text/html"])

# body_of_email can be plaintext or html!                    
content = headers + "\r\n\r\n" + "body_of_email"
session.sendmail('[email protected]', '[email protected]', content)

just remember if your email is gmail after first run you get an error. after that you should login to your email account and approve access to your account from another app ( you will receive a messege after login)

It seems as if you require something that Google calls an app password.

Basically, you generate a 16 digit password, which is unique to your app. You enter this specific password in the python program, instead of the password you regularly use to log into your Google account.

This allows you to still enjoy the benefits of 2-step verification while also being able to use third party applications, such as your own python program.

Here are the instructions from Google on how to generate such an app password: https://support.google.com/accounts/answer/185833?hl=en
