Whats the code you have so far?
You should store all of the email adresses in a database, btw.
Anyway:
[tt]
<?php
$filename = "addresses.txt";
$fd = fopen ($filename, "r"

;
$contents = fread ($fd, filesize ($filename));
fclose ($fd);
$addrs = split(",",$addresses);
for ($i=0; $i<count($addrs); $i++) {
mail($addrs[$i],"subject","body of the email"

;
}
?>
[/tt]
Assume that the addresses.txt text file that contains all of the addresses separated by comma's. Then, PHP opens the file, splits it up into an array, and then loops through the array, mailing the info that you want to each person.
Hope this helps.
