PHP Mailer Multiple recipients

Question

I'm using php mailer for mail triggering. Its working fine. But I gave 2 to 5 recipients, it sends the mail to only one recipient. In future, I have to trigger a mail to nearly 100 recipients.. I've shared my code below.. Please check it..

 require 'phpmailer/PHPMailerAutoload.php'; 

    $mail = new PHPMailer;

    //$mail->SMTPDebug = 3;                               // Enable verbose debug output

    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'karthick****@gmail.com';                 // SMTP username
    $mail->Password = '********';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to

    $mail->setFrom('karth*******@gmail.com', 'A**n');

    $addresses = explode(',',$emailM);
    foreach ($addresses as $address) {
        $mail->AddAddress($address);
    }


$mail->isHTML(true);                                  

$mail->Subject = 'Need for '.$keyword.'';
$mail->Body    = 'Hi,The Message';


if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Qoute has been sent to all the Manufacturers';
    echo "$address";

}

Are the email addresses in `$addresses` valid? You should at least add debug message in each foreach-loop cycle. — Raptor, Jan 10 '17 at 07:28
Are you sure it's only sending to one? You're echoing `$address` at the end, which will only ever contain the last address you added, but the message will still be sent to all of them (though you should check the return value of `addAddress()` to be sure it's working). — Synchro, Jan 10 '17 at 07:44
I don't think you're going about this in the right way - given the "all the Manufacturers" text at the end, I doubt very much you really want to be adding them all to the same message (where they will all see each other's addresses). You should send a separate message to each one. See [the mailing list example provided with PHPMailer](https://github.com/PHPMailer/PHPMailer/blob/master/examples/mailing_list.phps) for how to do that efficiently. — Synchro, Jan 10 '17 at 07:52
$emailM shows email1@gmail.comemail2@gmail.comemail3@gmail.com.... $address shows email1@gmail.com.. — Arun Karthick, Jan 10 '17 at 08:56

A basic idea is that make different connection (object) for each your mailing address like below if You don't have so much addresses in your array.

 require 'phpmailer/PHPMailerAutoload.php'; 

$addresses = explode(',',$emailM);
    foreach ($addresses as $address) {
    $mail = new PHPMailer;

    //$mail->SMTPDebug = 3;                               // Enable verbose debug output

    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'karthick****@gmail.com';                 // SMTP username
    $mail->Password = '********';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to

    $mail->setFrom('karth*******@gmail.com', 'A**n');


        $mail->AddAddress($address);


$mail->isHTML(true);                                  

$mail->Subject = 'Need for '.$keyword.'';
$mail->Body    = 'Hi,The Message';


if(!$mail->send()) {
    echo 'Message could not be sent.';
    echo 'Mailer Error: ' . $mail->ErrorInfo;
} else {
    echo 'Qoute has been sent to all the Manufacturers';
    echo "$address";

 }

UPDATE :

The second idea is that you can remove recepients each time and add new one and then send like below

require 'phpmailer/PHPMailerAutoload.php'; 

    $mail = new PHPMailer;

    //$mail->SMTPDebug = 3;                               // Enable verbose debug output

    $mail->isSMTP();                                      // Set mailer to use SMTP
    $mail->Host = 'smtp.gmail.com';  // Specify main and backup SMTP servers
    $mail->SMTPAuth = true;                               // Enable SMTP authentication
    $mail->Username = 'karthick****@gmail.com';                 // SMTP username
    $mail->Password = '********';                           // SMTP password
    $mail->SMTPSecure = 'tls';                            // Enable TLS encryption, `ssl` also accepted
    $mail->Port = 587;                                    // TCP port to connect to

    $mail->setFrom('karth*******@gmail.com', 'A**n');

    $addresses = explode(',',$emailM);
    foreach ($addresses as $address) {

        // for clear last recipients

        $mail->ClearAllRecipients( ) 


        $mail->AddAddress($address);


        $mail->isHTML(true);                                  

           $mail->Subject = 'Need for '.$keyword.'';
           $mail->Body    = 'Hi,The Message';


        if(!$mail->send()) {
          echo 'Message could not be sent.';
          echo 'Mailer Error: ' . $mail->ErrorInfo;
       } else {
           echo 'Qoute has been sent to all the Manufacturers';
          echo "$address";

       }

 }

Don't do that. It will work, but it's slow, wasteful and inefficient. — Synchro, Jan 10 '17 at 07:38
No, not true. PHP Mailer can support multiple Recipients at the same time. — Raptor, Jan 10 '17 at 07:38
i knew it. but when you are continously adding addresses and then send it will shows all receipient in each of receipients — Satish Sharma, Jan 10 '17 at 07:40
Even with that edit, you're still adding overhead simply because you have some aversion to calling `clearAddresses()`. — Synchro, Jan 10 '17 at 07:41
...and your second edit is nearly the same as the original post, but makes the same mistake as marmalade's answer :) — Synchro, Jan 10 '17 at 07:45
@Synchro use my second update and try. i think you will get your answer. — Satish Sharma, Jan 10 '17 at 07:49
That's better, though there's more you could move outside the loop, but I think the OP was asking the wrong question - see my comment on the question. — Synchro, Jan 10 '17 at 07:54
I tried ur code @SatishSharma... But its showing error like this... Message could not be sent.Mailer Error: You must provide at least one recipient email address. — Arun Karthick, Jan 10 '17 at 07:55
@Arun, that suggests that some of your addresses are invalid, and you're not checking the results of `addAddress`, so you end up trying to send messages with no recipient. — Synchro, Jan 10 '17 at 09:23
@ArunKarthick your `$addresses` must have valid no of emails — Satish Sharma, Jan 10 '17 at 09:30
This is kinda the recommended way of sending by PHPMailer https://github.com/PHPMailer/PHPMailer/blob/master/examples/mailing_list.phps — Whip, Mar 23 '21 at 09:21

You're code looks like it should be doing the trick. Make sure that $address doesn't contain any whitespace for the entries. For safe measure, add the trim() function.

$mail->AddAddress(trim($address));

If that does not work, make sure that you're recipient addresses are real.

Additionally, in case the privacy of the recipients is of concern, I would recommend you use AddBCC() instead of AddAddress() so that their addresses are not revealed.
