Content management systems Joomla

I've produced two seperate pages to have an old Joomla 1: system The search engine optimization friendly choice is not available as well as for various reasons I cant touch/update the joomla system

The main executive wants to produce a newletter having a specific url So First of all I have to create this subdomain kingdom/mysports to appraise the rate of success from the mail campaign

I should also link that subdomain domain towards the content page below

An amount you say are the most useful choices for carrying this out in Joomla
