Automatically, regularly send out emails, store this program on your ISP, cgi

This cgi program automatically emails a message to your client list. The message is contained in a file which can be named according to the day of the month, so you can automatically send a different message for each day of the month, if you so wish (file1, file2, file3 > file 31). This is helpful for reducing repetitiveness, tips of the day etc. This program contains the facility to start or not on specific days. So, for example, you can tell it to send emails on Mondays and Wednesdays and Fridays but not Tuesdays and Thursdays and weekends. So you only need to program the cron job sites above to run the program at certain times everyday. The program itself will know if it is the right day to run or not. So, for example, if you set the timing on the cron job sites to 10am everyday and set the day within the program to Monday, Wednesday and Friday only, then the program will trigger every day at 10am but will only send out a message to your email list on Mondays, Wednesdays and Fridays. This prevents you from having to set the program up for various days on the cron job sites.
