How to format email for gmail?

I wrapped the email's body in <html><body><pre>. Show original in gmail gives me actually how I want the email to be formatted:

Mime-Version: 1.0
Content-Type: text/html;
 charset=UTF-8
Content-Transfer-Encoding: 7bit


Ant run name    : Basics of Edumate
Overall result  : pass

Ant run took: 4 minutes 15 seconds

--------------------------
Details for all test suits
--------------------------

login           : Pass
AddCycleTemplate: Pass
AddCycleTemplate: Pass
AddAcademicYear : Pass
AddAcademicYear : Pass

But the actual email is displayed as one line. Note that space that I use to align : is somehow omitted as well as new lines.

I send the email from ruby using pony.

Any suggestions how to get the formatting inside gmail as desired?

Solution

This the was I send html email to gmail. I guess what I was missing was :html_body => body, part of pony's settings.

def email_it(body, subject,to,from)
  $smtp = 'mail.com.au'
  $smtp_port = 25
     Pony.mail(
        :to => to, 
        :from => from,
        :subject => subject, 
        :body => Nokogiri::HTML(body).text, 
                    :html_body =>  body,
        :via => :smtp, 
        :via_options => {
                :address     => $smtp,
                :port     => $smtp_port,
                :enable_starttls_auto => false
        }
    )
end
