Sending massive amount of emails

[Pain]

Hello. I have a problem. 

 

I am trying to send approximately 1200 emails at once. Each email has to be retrieved from the database. 

<?php
...
$query = mysql_query("SELECT * FROM mass_subscribers");
while($row = mysql_fetch_assoc($query)) {
   $email = $row['email'];
   $name = $row['name'];
 
   $mail = new SendGrid\Mail();
   $mail->
   setTo($email)->
   setFrom('me@yahoo.com')->
   setSubject($subject)->
   setText($message)->
   setHtml($message);
  
   $sendgrid->web->send($mail);
}
...
?>

 

Problem is the loop gets executed 1200 times which causes 500 error. Is there any way around this? Thank you, any advice appreciated guys.

Could you not import your email addresses into a list array, then send the email from the list array

Are you referring to the php's list() function?

Can you explain this in more detail please? Thank you.

I did put all the emails into an array. 

$email = array();
$name = array();
 
 
 $query = mysql_query("SELECT * FROM test");
 while($row = mysql_fetch_assoc($query)) {
 
            $name[] = $row['name'];
            $email[] = $row['email'];
 
 
 
         }
 
$email = implode(",", $email);
$name = implode(" ", $name);

This is now the main problem as the email gets sent to the first recipient in the database only.

 
$mail = new SendGrid\Mail();
             $mail->
             addTo($email)->
             setFrom('test@test.com')->
             setSubject($subject)->
             setText($message)->
             setHtml($message);
  
             $sendgrid->web->send($mail); 

PHPs built-in mail () function works properly, but i have to use sendgrid for this one. I'm lost:/

Can I see the format of all emails after imploding?

while($row = mysql_fetch_assoc($query)) {
 
            $name[] = $row['name'];
            $email[] = $row['email'];
 
 
 
         }
 
$email = implode(",", $email);

echo $email;

Email@yahoo.com,email2@yahoo.com,email3@yahoo.com etc.

Try to add manually more than one email.

Something like -

<?php
$mail = new SendGrid\Mail();
$mail->
  addTo('foo1@bar.com','foo2@bar.com','foo3@bar.com')->
  setFrom('me@bar.com')->
  setSubject('Subject goes here')->
  setText('Hello World!')->
  setHtml('<strong>Hello World!</strong>');

// send emails
  $sendgrid->
  web->
  send($mail);

?>
