Send email with multiple messages to different users in sendgrid - php

Question

We are using sendgrid for email,
we have tried,
$email = new SendGrid\Email();
$emails = array("foo#bar.com", "another#another.com", "other#other.com");
$email->setTos($emails);
$email->setHtml(array($message1,$message1));
$sendgrid->send($email);
How to set different - different $email->setHtml(array($message1,$message1)) at a time.

Answer 1

As per I understand from your question you want to send different messages to different email ids. Which can be achieve by
$email = new SendGrid\Email();
$emails = array("foo#bar.com", "another#another.com", "other#other.com");
$message = array("message1","message2","message3"); //create a array of messages according to email ids
$i =0 ;
foreach ($emails as $value) {
$email->setTos($value);
$email->setHtml($message[$i]);
$sendgrid->send($email);
$i++;
}

Answer 2

As your question is confusing, I will assume you want to send different email messages to all users in the list. So:
$email = new SendGrid\Email();
$emails = array("foo#bar.com", "another#another.com", "other#other.com");
$messages = array("message1", "message2");
foreach ($messages as $msg) { // Grab every message...
$email->setTos($emails); // for everyone...
$email->setHtml($msg); // set it as the body...
$sendgrid->send($email); // and send it.
}
