How To Send Automated Emails After Certain Period Of Time ?

Hi,

I would like to know how reminder emails can be sent automatically to registered users ?

Thanks

For that make a cron job in your system that will run at particular interval and when it runs send the mails.

Is there an example which I can refer to create a cron job ??
