    // We want to build a multipart/alternative email, where the 1st alternative body
    // is text/plain, the 2nd is text/x-amp-html, and the last is text/html.
    // (Some email clients will only render the last MIME part, so we recommend placing the text/x-amp-html MIME part before the text/html MIME part.)

    // First create a plain-text email body:
    email.AddPlainTextAlternativeBody("Hello World in plain text!");

    // Now add the text/x-amp-html.
    email.SetTextBody(sbAmp4Html.getAsString(),"text/x-amp-html");

    // Now add an HTML body..
