Per the discussion thread that I started here, Marketo Support confirmed back to me that the email editor does not retain specific code in the <head> of the template; and strips out specific conditional code (media queries) that are essential especially for responsive emails. Please fix this so that our code is not being rewritten or stripped from our email templates.
I know there already is an idea (since 2013) that is specific to stripping out conditional code within the HTML. This idea covers more than just the conditional code. So please don't merge this with that idea.
Our template:
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:v="urn:schemas-microsoft-com:vml"
xmlns:o="urn:schemas-microsoft-com:office:office">
<head>
Marketo rewrite:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
<html>
<head>
Our template:
<meta http-equiv="X-UA-Compatible" content="IE=edge" />
<meta name="viewport" content="width=device-width, initial-scale=1">
<!--[if gte mso 9]><xml>
<o:OfficeDocumentSettings>
<o:AllowPNG/>
<o:PixelsPerInch>96</o:PixelsPerInch>
</o:OfficeDocumentSettings>
</xml><![endif]-->
Marketo rewrite: completely stripped out. Basically, Marketo is stripping out any conditional code that starts with "<!--[if gte mso 9]>"
