Send the same email to multiple recipients without them seeing each other

[mithunjj]

I'm using the official PHP library.

I've read this: https://sendgrid.com/docs/Classroom/Send/v3_Mail_Send/personalizations.html#-Sending-the-same-Email-to-Multiple-Recipients

But, I would like to send the same email to multiple recipients without them seeing each other.

Is it possible using the official library?

Any code examples would be deeply appreciated.

Please help.

[offerwise]

I am having the same challenge here. Would really appreciate code example.

Hello @mithunjj, @offerwise,

It sounds like this is the scenario you require.

For each request body, you would have a different personalization for each recipient, but a shared subject and content body. Here is an example where you have 2 personalizations. I hope that helps!

With Best Regards,

Thanks @thinkingserious

I will test the example.

But the title of this is very confusing. I would recommend it to be Sending the same Email to Multiple Recipients without revealing each others email

Hi,

I am using this php library (V3 with cURL)

At first, I am using this code below

... $arr1['personalizations'][0]['to'][]=['name'=>'NAME 1','email'=>'xxx@xxx.xxx']; $arr1['personalizations'][0]['to'][]=['name'=>'AVOR GMail','email'=>'yyy@yyy.yyy']; $arr1['subject']='Multiple Mail with comma'; $arr1['from']=['name'=>'TEST Info','email'=>'zzz@zzz.zzz']; $arr1['content'][]=['type'=>'text/html','value'=>'Heya!']; $arr1['template_id']=_SENDGRID_TEMPLATE__; ...

The result : http://prntscr.com/cy4r63

And then accidentally I'm edit the code (line 1 and 2) From $arr1['personalizations'][0]['to'][] into $arr1['personalizations'][]['to'][]

... $arr1['personalizations'][]['to'][]=['name'=>'AVOR RR','email'=>'xxx@xxx.xxx']; $arr1['personalizations'][]['to'][]=['name'=>'AVOR GMail','email'=>'yyy@yyy.yyy']; $arr1['subject']='Multiple Mail with comma'; $arr1['from']=['name'=>'TEST Info','email'=>'zzz@zzz.zzz']; $arr1['content'][]=['type'=>'text/html','value'=>'Heya!']; $arr1['template_id']=_SENDGRID_TEMPLATE__; ...

It have same result with non cURL script

... $personalization1=new SendGrid\Personalization(); $to1=new SendGrid\Email('AVOR RR','xxx@xxx.xxx'); $personalization1->addTo($to1);

$personalization2=new SendGrid\Personalization(); $to2=new SendGrid\Email('AVOR GMail','yyy@yyy.yyy'); $personalization2->addTo($to2);

$content=new SendGrid\Content('text/html','some text here');

$mail=new SendGrid\Mail(); $mail->setFrom($from); $mail->setSubject($subject); $mail->addContent($content); $mail->addPersonalization($personalization1); $mail->addPersonalization($personalization2); $mail->setTemplateId(_SENDGRID_TEMPLATE__); ...

And the results like this : http://prntscr.com/cy4son and the second email : http://prntscr.com/cy4swe Hope this can help someone

Elmer,

That helps, but is there a way to send the same email personalized with unique name and a link substitution to each recipients, without having to make 10,000 api send calls to send grid. Basically sending in an array of emails and substitutions on a single API send call and then have your servers sort out the individual sends.

Example:

Email 1: Hello Rob

Click on this link: http://example.com/rob

Email 2: Hello Steve

Click on this link: http://example.com/steve

Etc.

Does that make sense?

Hello @mithunjjhttps://github.com/mithunjj, @offerwisehttps://github.com/offerwise,

It sounds like thishttps://sendgrid.com/docs/Classroom/Send/v3_Mail_Send/personalizations.html#-Sending-Two-Different-Emails-to-Two-Different-Groups-of-Recipients is the scenario you require.

For each request body, you would have a different personalization for each recipient, but a shared subject and content body. Here is an examplehttps://github.com/sendgrid/sendgrid-php/blob/master/examples/helpers/mail/example.php#L22 where you have 2 personalizations. I hope that helps!

@offerwise,

Each email would have it's own personalization block, which would have a substitution object to handle the differing salutations and links. Similar to what you see here, except there would be multiple personalization objects.

@wongalus,

Thanks for sharing your solution, please take a moment to fill out this form so that we may send you some swag!

[mithunjj]

@wongalus The code is working. Thanks

Here is the sample code that I'm using to send to multiple recipients.

$recipients = array('1@example.com', '2@example.com');        
$personalization = array();
$recp_cnt = count($recipients);

        for ($i = 0; $i < $recp_cnt; $i++) {
            $personalization[$i] = new SendGrid\Personalization();
            $recipient = new SendGrid\Email(NULL, $recipients[$i]);
            $personalization[$i]->addTo($recipient);
        }

        for ($i = 0; $i < $recp_cnt; $i++) {
            $mail->addPersonalization($personalization[$i]);
        }

But there is one problem left, if I set a CC/BCC using addCc or addBcc method for the same email, its not working.

[thinkingserious]

Hi @mithunjj,

Could you please provide a bit more detail? Can you share the code that is not working as expected?

[kotakkreatif]

@mithunjj

I think the main problem is Sendgrid cannot send email with duplicated items inside personalization

All of the recipients in a single personalization object (either in the to, cc, or bcc fields), will see exactly the same email, as defined by the data in that personalization, as such we do not allow duplicate emails between these three arrays in a single personalization.

From : _https://sendgrid.com/docs/Classroom/Send/v3_Mail_Send/personalizations.html_

You must use very different Name and email address for every personalization.

This is my working code

$tos=[
    [null,'test1@gmail.com'],
    [null,'test2@gmail.com'],
    [null,'test3@gmail.com']
];
$ccs=[
    [null,'xxx@xxx.com'],
    [null,'yyy@yyy.com'],
    [null,'zzz@zzz.com']
];
$bccs=[
    [null,'aaa@aaa.com'],
    [null,'bbb@bbb.com'],
    [null,'ccc@ccc.com']
];

foreach($tos as $key=>$val){
    $personalization=new SendGrid\Personalization();
    $to=new SendGrid\Email($val[0],$val[1]);
    $cc=new SendGrid\Email($ccs[$key][0],$ccs[$key][1]);
    $bcc=new SendGrid\Email($bccs[$key][0],$bccs[$key][1]);

    $personalization->addTo($to);
    $personalization->addCc($cc);
    $personalization->addBcc($bcc);
    $mail->addPersonalization($personalization);
}

The result : http://prntscr.com/d1yp2s

[mithunjj]

@wongalus Your code is working great!

Thanks :-)

[thinkingserious]

Thanks for taking the time to share the solution @wongalus. We would love to send some swag your way, do you mind filling out this form?

[morazain]

I have created a php test program which sends out the an email to multiple recipients, personalized by recipient. It's attached for your perusal. Hope you find it useful! test3m.zip

[thinkingserious]

Thank you @morazain!

Would you consider making a PR to this file with your example?

With Best Regards,

Elmer

[morazain]

I would be happy to, but not sure as to how to go about it.

​Is a PR a Pull Request?

[thinkingserious]

Hi @morazain,

Yes, PR means Pull Request in this context.

I have slightly modified the send_test_email in the current plugin to support multiple email recipients, as per the comments above, so posting here maybe it could be useful to someone else:

                // check headers
        $headers = $params['sendgrid_headers'];

        // validate headers
        if ( ! self::valid_emails_in_headers( $headers ) ) {
            return array(
                'message' => 'One or more email addresses in field "headers" are not valid.',
                'status' => 'error',
                'error_type' => 'sending'
            );
        }

        // void email
        $mail = new \SendGrid\Mail();

        // subject
        $subject = stripslashes( $params['sendgrid_subj'] );
        $mail->setSubject($subject);

        // body
        $body    = stripslashes( $params['sendgrid_body'] );
        if ( preg_match( '/content-type:\s*text\/html/i', $headers ) ) {
            $body_br = nl2br( $body );
        } else {
            $body_br = $body;
        }
        $content = new \SendGrid\Content("text/html", $body_br);
        $mail->addContent($content);

        // from
        $from = new \SendGrid\Email(SG_FROM_NAME, SG_FROM_EMAIL);
        $mail->setFrom($from);

        // get recipients emails - from comma separated list $to
        $to = $params['sendgrid_to'];
        $recipients = explode(',', $to);
        $recpCount = count($recipients);

        for ($i = 0; $i < $recpCount; $i++) {
            $personalization = new \SendGrid\Personalization();
            $recipient = new \SendGrid\Email(NULL, $recipients[$i]);
            $personalization->addTo($recipient);
            $mail->addPersonalization($personalization);
        }

        // send
        $apiKey = SG_APIKEY;
        $sg = new \SendGrid($apiKey);
        $response = $sg->client->mail()->send()->post($mail);

        if ( 202 === $response->statusCode() ) { // accepted
            return array(
                'message' => 'Email was sent.',
                'status' => 'updated'
            );
        }

        return array(
            'message' => 'Email wasn\'t sent.',
            'status' => 'error',
            'error_type' => 'sending'
        );
