HTML Email doesn't send (python3)

I'm trying to send an HTML email, however, when I run this code, literally nothing happens. I sit and wait as the program never finishes. What did I do wrong?

import smtplib, ssl, getpass
from email.mime.text import MIMEText
from email.mime.multipart import MIMEMultipart
port = 465
smtp_server = "smtp.gmail.com"
sender_email = "REDACTED"  
receiver_email = "REDACTED"
password = getpass.getpass()
html = """
<html>
<head></head>
<body>
    <h1>HEADER</h1>
    <br>
    body<br>
</body>
</html>
"""
msg = MIMEMultipart()
attach = MIMEText(html, 'html')
msg.attach(attach)

context = ssl.create_default_context()
with smtplib.SMTP_SSL(smtp_server, port, context=context) as server:
    server.login(sender_email, password)
    server.sendmail(sender_email, receiver_email, msg)
    server.close()

The msg needs to be flattened to a string before passing it to the sendmail method:

server.sendmail(sender_email, receiver_email, str(msg))

Also, you'll probably want to set some headers on the msg object:

msg.add_header('From', sender_email)
msg.add_header('Subject', 'whatever')

Enabling the debug output for the SMTP object would help to track down these problems, try inserting this line above the server.login call:

server.set_debuglevel(1)

If you're going to be working with email though it may be worth looking in to the email.message.EmailMessage class.

I've found sending mail using gmails SMTP server hard and difficult to work out (The only way I have even gotten it to work is by using a temporary thing that lets me send emails through my email address and only works half the time)

Instead, I suggest sending your email through SendGrid, using their python API, or another service that offers a similar function (Not being biased just have used SendGrid before and found it very easy and reliable) and just send a request to that every time you want to send an email.

I know its a dodgy way to get it to work but its the only way I've been able to send emails through my Gmail account using python :)

(Id comment this as it isn't really an answer but a workaround however I don't have enough reputation)
