How can I set the form layout in email?

Hi,
I have the same InfoPath form. When I preview test send while in InfoPath Designer 2010, I received the email with the form in the nice format, same as it was shown in design.
I published it to SharePoint InfoPath form service web browser form and it showed on the screen correctly but once submitted to my email, it was very wide.
How can I set the form layout sent from SharePoint web browser form to the same as designed to my email?
Thanks.
