IWeb Problem with XML in Email Newsletters

Hello,

We have recently completed a great looking newsletter using IWeb.

Unfortunately when we send this newsletter out it looks fine in Microsoft Outlook but in any webmail program e.g. hotmail, gmail etc it looks all distorted. Also when you forward the email on from outlook it distorts.

We believe that this is to do with the email being XML and not pure html.

Is there anyway to publish work from iweb into pure html or is another design program required?

If so do you have any recommendations on programs which you can drag and drop to design but you can output the design to pure html so they will work fine with webmail based emails as well as outlook.

Many thanks for your time,

Johnson
