HTML e-mail configuration

You can send the verification emails as HTML, by specifying html_body instead of body; for example:

REST_REGISTRATION = {
    ...

    'REGISTER_VERIFICATION_EMAIL_TEMPLATES': {
        'subject':  'rest_registration/register/subject.txt',
        'html_body':  'rest_registration/register/body.html',
    },

    ...
}

This will automatically create fallback plain text message from the HTML. If you want to have custom fallback message you can also provide separate template for text:

REST_REGISTRATION = {
    ...

    'REGISTER_VERIFICATION_EMAIL_TEMPLATES': {
        'subject':  'rest_registration/register/subject.txt',
        'text_body':  'rest_registration/register/body.txt',
        'html_body':  'rest_registration/register/body.html',
    },

    ...
}
