If they have given you permission to email them, you just need to write a script to send the email and then add it as a cronjob to run on the 15th and 27th of every month. you should look into storing the emails in a database; this way you can use the same script over and over, and you just need to add the email into the database. The cronjob will then send it on the time and date you specify. You can find out more about cron here, although if you have cpanel on your server it is even simpler to do it through the frontend; http://adminschoice.com/crontab-quick-reference
