Q:

php - PHPMailer: Mass Emails - Send all variable messages at once, instead of individually

Hey there,

I'm currently working on a PHP project where I need to send mass emails using PHPMailer. I have everything set up and working fine, but there's one thing I'm struggling with.

Currently, I'm looping through a list of recipients and sending each message individually. While this works, it is quite time-consuming, especially when I have a large number of recipients.

I was wondering if there is a way to send all the variable messages at once instead of sending them one by one. This would greatly improve the efficiency of my code and reduce the time it takes to send the emails.

Any help or insights on how to achieve this would be greatly appreciated. Thanks in advance!

Hello,

I faced a similar issue while working on a project and found an alternative solution to send all variable messages at once with PHPMailer. Instead of using the `sendMultiple` method, you can utilize the power of PHP's `implode` function to concatenate the messages together and send them as one email.

Here's how you can achieve this:

php
// Create a string variable to store all the email messages
$allMessages = '';

// Loop through your list of recipients
foreach($recipients as $recipient) {
// Create a new PHPMailer instance for each recipient
$mail = new PHPMailer();

// Set up your email details
$mail->Subject = 'Your email subject';
$mail->setFrom('your_email@example.com', 'Your Name');
$mail->addAddress($recipient['email'], $recipient['name']);

// Set up the body of the email (content, variables, etc.)
$message = 'Hello, ' . $recipient['name'] . '! The content of your email goes here.';
$allMessages .= $message . "\n"; // Concatenate each message with a line break
}

// Create a new instance of PHPMailer
$mailer = new PHPMailer();

// Set up the email body as the concatenated messages
$mailer->Body = $allMessages;

// Finally, send the email
$mailer->send();

// Clear the concatenated messages for future use
$allMessages = '';


In this approach, I'm creating a string variable called `$allMessages` to store all the email messages. Inside the loop, I'm concatenating each message to this variable with a line break using the `.=` operator. Finally, I'm setting the concatenated messages as the body of the email and sending it through PHPMailer.

Using this technique, you can send all the variable messages as one email instead of individual emails.

I hope this suggestion is helpful to you. Feel free to ask if you have any further questions!

Hey everyone,

I encountered a similar situation lately and wanted to share an alternative approach to send variable messages at once with PHPMailer. Instead of concatenating the messages into a single body, you can utilize PHPMailer's built-in support for sending emails in bulk using SMTP.

Here's how you can achieve this:

php
// Create a new instance of PHPMailer
$mailer = new PHPMailer();

// Set up your email details (subject, from, etc.)
$mailer->Subject = 'Your email subject';
$mailer->setFrom('your_email@example.com', 'Your Name');

// Loop through your list of recipients
foreach($recipients as $recipient) {
$mailer->addAddress($recipient['email'], $recipient['name']);

// Set up the body of the email (content, variables, etc.)
$message = 'Hello, ' . $recipient['name'] . '! The content of your email goes here.';
$mailer->Body = $message;

// Send the email for each recipient
$mailer->send();

// Reset the email details for the next recipient
$mailer->clearAllRecipients();
}

// Clear any remaining properties for future use
$mailer->ClearAll();



With this approach, you are still looping through your recipients, but instead of sending all the emails at once, you're adding each recipient individually and sending the email within the loop. By clearing the recipients after sending each email, PHPMailer is ready to accommodate the next recipient. This way, you maintain the efficiency of sending bulk emails without the need for concatenating messages.

I hope this approach proves useful in your case. If you have any further queries, feel free to ask!

Hey,

I had a similar requirement in the past, and I found a solution to send all the variable messages at once using PHPMailer. Instead of sending each email individually in a loop, you can create an array of messages and recipients, and then use the `sendMultiple` method of PHPMailer to send them all together.

Here's how you can do it:

php
// Create an array to store all the email messages and recipients
$emailData = array();

// Loop through your list of recipients
foreach($recipients as $recipient) {
// Create a new PHPMailer instance for each recipient
$mail = new PHPMailer();

// Set up your email details (subject, from, etc.)
$mail->Subject = 'Your email subject';
$mail->setFrom('your_email@example.com', 'Your Name');
$mail->addAddress($recipient['email'], $recipient['name']);

// Set up the body of the email (content, variables, etc.)
$message = 'Hello, ' . $recipient['name'] . '! The content of your email goes here.';
$mail->Body = $message;

// Add the PHPMailer instance to the emailData array
$emailData[] = $mail;
}

// Create a new instance of PHPMailer
$mailer = new PHPMailer();

// Loop through the emailData array and add each PHPMailer instance
foreach ($emailData as $email) {
$mailer->addCustomMessage($email);
}

// Finally, send all the emails at once
$mailer->sendMultiple();

// Clear the emailData array for future use
$emailData = array();


By using this approach, all the variable messages will be added to the `emailData` array, and then sent all together using the `sendMultiple` method. This will significantly speed up the email sending process.

I hope this helps! Let me know if you have any further questions.
