Rails3 Mailer html / text versions order

I am sending the emails as per the documentation order : html / text but users are receiving the text version first and not the html ( need to switch to an alternative version ..) I guess I missed a point but which one ?

thanks for your help

RAILS DOC ======== class UserMailer < ActionMailer::Base   default :from => "notifications@example.com"

  def welcome_email(user)     @user = user     @url = "http://example.com/login&quot;     mail(:to => user.email,          :subject => "Welcome to My Awesome Site") do |format|       format.html { render 'another_template' }       format.text { render 'another_template' }     end   end

MY USER MAILER ======= def analysis_received(user_id, clip_id, request_id)      ...... skipped lines ......      @template = "user_mailer/#{I18n.locale.to_s}/ analysis_received.erb"        mail(:to => @user[:email], :subject => "#{@request_type.capitalize}") do |format|           format.html { render :template => @template }           format.text {render :layout => false, :template => @template}        end     end end
