Hi, here is my code: [quote] $result = mysql_query("SELECT email FROM $database_table") or die ("$header<br><br><center><font color=\"#FFFF00\" size=\"3\"><img title=Warning! border=0 src=images/warn.gif>$error_mysql_query</font><br><br><img title=FYI border=0 src=images/info.gif>Help Info: Make sure you have edited the config.php file correctly.</font><br><br><a title='Go Back' href=javascript:history.go(-1)><font color=\"#FFFFFF\" size=\"3\">[ Go Back ]</font></a></center>"); $recordnum = mysql_num_rows($result); print "$header<br><br><center><font color=#FFFFFF size=3>$recordnum HTML emails were succesfully sent. Here is a list:</font><br>"; while ($qry = mysql_fetch_array($result)) { $email = $qry[email]; $headers = "From: $company_name <$contact_email>\n"; $headers .= "MIME-Version: 1.0\n"; $headers .= "Content-Type: text/html; charset=ISO-8859-1\n"; $headers .= "X-Mailer: PHP \n"; $message = "$htmlbody<br><br>"; $optoutlink = "http://www.zoneski.com/concours"; $optoutlink .= '/unsubscribe.php?action=unsub&email='; $optoutlink .= "$email"; $message .= "<font color=#ffffff size=2 face=arial>$optoutmessage</font><br>"; $message .= "<font size=2 face=arial><a target=\"_blank\" href=$optoutlink>Cliquez ici pour ne plus recevoir de courriel de notre part.<a></font><br>"; mail($email, $subject, $message, $headers); print "$email<br>"; }}}[/quote] I want to add something so that every 50 transactions or so, it does somekind of a wait of 15 seconds let's say. This way, my php-sendmail works real fine for all of my 2000 people. Thanks in advance
