Don't show other recipients when sending multiple emails with JMail

Question

So this is my code where I send same email to 3 different users

$mailer->sendMail($emailfrom, $sitename, 'adam@malinator.com', $subject, $message, 1);
$mailer->sendMail($emailfrom, $sitename, 'a.fini@ambulatoriprivati.it', $subject, $message, 1);
$mailer->sendMail($emailfrom, $sitename, 'adam.madrzejewski@gmail.com', $subject, $message, 1);

And this is what I see in my gmail (My email is the last one adam.madrzejewski@gmail.com):

But I don't want that all successive recipients see to who email was sent before. How can it be solved? I can't find anything on JMail's API page:

https://api.joomla.org/cms-3/classes/JMail.html

Using Joomla 3.5.1

Answer 1

As you can see on the API reference page, the sendMail() function has a $bcc parameter:

sendMail(string $from, string $fromName, mixed $recipient, string $subject, string $body, boolean $mode = false, mixed $cc = null, mixed $bcc = null, mixed $attachment = null, mixed $replyTo = null, mixed $replyToName = null)

Also, if you're sending the same email to 3 different recipients, you don't need to use the sendMail() function 3 times, but instead, simply define an array of recipients.

Have a try of the following:

$to = array(
    'adam@malinator.com'
);

$bcc = array(
    'a.fini@ambulatoriprivati.it',
    'adam.madrzejewski@gmail.com'
);

$mailer->sendMail($emailfrom, $sitename, $to, $subject, $message, 1, null, $bcc);

Answer 2

There are 2 solutions you can try of the following.

• By avoiding the mailer instance : $mailerand using the following code -

JFactory::getMailer()

JFactory::getMailer()->sendMail($emailfrom, $sitename, 'adam@malinator.com', $subject, $message, 1);
JFactory::getMailer()->sendMail($emailfrom, $sitename, 'a.fini@ambulatoriprivati.it', $subject, $message, 1);
JFactory::getMailer()->sendMail($emailfrom, $sitename, 'adam.madrzejewski@gmail.com', $subject, $message,1);`

• Take an array of recipients and place the mailer instance inside the loop as following -

$mailer

$recipients = array('email1','email2','email3' );
for($i=0;$i<3;$i++){
    $mailer = JFactory::getMailer();
    $mailer->isHTML(true);
    $mailer->Encoding = 'base64';
    $mailer->setSubject('Your subject string');
    $mailer->setBody($body);
    $mailer->addRecipient($recipients[$i]);
    $mailer->setSender($sender);
    $send = $mailer->Send();
}

Answer 3

Joomla Mailer extends the PHPMailer, so you can add this line of code after the send()

$mailer->clearAllRecipients();
