Answer 1

I learned to this from one of the examples in the book I am learning PHP from, Head First PHP & MySQL.

What you can do is send each e-mail individually, but simultaneously, through a while loop. With a mysqli_query selecting the e-mails, make a while loop that goes through my

while ($row_data = mysqli_fetch_array($your_query_in_a_variable)) {

    // Then you will set your variables for the e-mail using the data 
    // from the array.

    $from = 'you@yoursite.com';
    $to = $row_data['email']; // The column where your e-mail was stored.
    $subject = 'Open Me!';
    $msg = 'Hello world!';
    mail($to, $msg, $from);
}

I hope that is clear. You basically just call the rows you want in your query, then use mysqli_fetch_array, which goes through each row every time it is called (someone correct me, if wrong) and will exit when there are no more rows left that were called.
