Sending Mailgun Inline Images in HTML using Python Requests library

As of 2020, actual documentation here: https://documentation.mailgun.com/en/latest/api-sending.html#examples

My example:

response = requests.post(
    'https://api.mailgun.net/v3/' + YOUR_MAILGUN_DOMAIN_NAME + '/messages',
    auth=('api', YOUR_MAILGUN_API_KEY),
    files=[
        ('inline[0]', ('test1.png', open('path/filename1.png', mode='rb').read())),
        ('inline[1]', ('test2.png', open('path/filename2.png', mode='rb').read()))
    ],
    data={
        'from': 'YOUR_NAME <' + 'mailgun@' + YOUR_MAILGUN_DOMAIN_NAME + '>',
        'to': [adresat],
        'bcc': [bcc_adresat],
        'subject': 'email subject',
        'text': 'email simple text',
        'html': '''<html><body>
            <img src="cid:test1.png">
            <img src="cid:test2.png">
            </body></html>'''
    },
    timeout=5  # sec
)

Sending Inline Images is documented here.

In the HTML, you'll reference the image like this: 

<html>Inline image here: <img src="cid:test.jpg"></html>

Then, define a Multidict, to post the files to the API:

files=MultiDict([("inline", open("files/test.jpg"))])
