How to Send an Email With Gmail as Provider Using Python

How to send an email with Gmail as provider using Python?

You need to say EHLO before just running straight into STARTTLS:

server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()

---

Also you should really create From:, To: and Subject: message headers, separated from the message body by a blank line and use CRLF as EOL markers.

E.g.

msg = "\r\n".join([
  "From: user_me@gmail.com",
  "To: user_you@gmail.com",
  "Subject: Just a message",
  "",
  "Why, oh why"
  ])

Note:

In order for this to work you need to enable "Allow less secure apps" option in your gmail account configuration. Otherwise you will get a "critical security alert" when gmail detects that a non-Google apps is trying to login your account.
