For some reason the Gmail API won't send an html email. Sending plaintext works fine:

var message = 'From: Me <[email protected]>\r\n' +
    'To: Me <[email protected]>\r\n' +
    'Subject: Hello\r\n\r\n'
    'World'

var raw = btoa(message)

Then when I try html, it just shows up as an empty message:

var message = 'From: Me <[email protected]>\r\n' +
    'To: Me <[email protected]>\r\n' +
    'Subject: Hello\r\n'
    'Content-Type: text/html; charset=utf-8\r\n' +
    'Content-Transfer-Encoding: quoted-printable\r\n\r\n' +
    '<html><body>' +
    '<h1>World</h1>' +
    '</body></html>'

var raw = btoa(message)

Any ideas? Maybe because it's not RFC 2822 pliant?

Reset to default 4

For starters you need to use base64url encoding, using the web/url safe alphabet not just the standard btoa() base64. If that doesn't fix it can you post your code and the exact error message you're getting? (Or does it work and not show up as html?)
