This is my first post.

It was decided to try and create web pages with an expiring date. The idea is when a web page has been up for a year, the unit that is responsible for the content of that web page will receive a notice that this web page has been up for a year and to please and check if the information is still valid. They have a chance to view the content and decide if the page can stay for another year or whatever is decided. So I created a meta tag with the expiring date. I have a simple script to check for the expiring date.

Each time the page is loaded onto a browser the script runs and sends an email each time. No one wants to get all these email. I need the email sent only once to the team responsible for the content and to our team. I would like to it to run once a day for three days.
Any suggestion would greatly appreciated, thanks for your help.
