dynamic content using one email template

  hi, we have embedded the dynamic content of  if, elseif statements within the email template html coding. For example, if a user signs up through our registration form and chooses preferences of having children within the age i) 0-2 , ii)5-11, and iii)11-18, we would like odm to be able to send the first e-mail to the user and will get the article for option i), the second e-mail send the user will get article for option ii), and the third email send the user will get article for option iii).
how can this be achieved? 

thanks,

Lana
