Send emails to multiple users using PHP/Javascript - php

I was trying to find an easier way to send e-mails to all my clients using our database (MySQL). I wanted to see if there is a way that it can select all the e-mails of my clients and I can add message, Subject and send it to all of my clients from my website rather than copying each of the mail.
Is there a way to integrate SMTP to do this? either using PHP or javascript.
Thanks.

Yes, there are about 5,247 ways. See these:
PEAR Mail
SwiftMailer
PHPMailer
Zend_Mail
Those are all good (and not the only ones). It is up to you to pick the one that best suits your purpose, there is no "single best" library.

I use SwiftMailer .. it works wonders for me.
* Send emails using SMTP, sendmail, postfix or a custom Transport implementation of your own
* Support servers that require username & password and/or encryption
* Protect from header injection attacks without stripping request data content
* Send MIME compliant HTML/multipart emails
* Use event-driven plugins to customize the library
* Handle large attachments and inline/embedded images with low memory use
require_once 'lib/swift_required.php';
//Create the Transport
$transport = Swift_SmtpTransport::newInstance('localhost', 25);
//Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
//Create a message
$message = Swift_Message::newInstance('Wonderful Subject')
->setFrom(array('john#doe.com' => 'John Doe'))
->setTo(array('receiver#domain.org', 'other#domain.org' => 'A name'))
->setBody('Here is the message itself')
;
//Send the message
$numSent = $mailer->batchSend($message);
printf("Sent %d messages\n", $numSent);
/* Note that often that only the boolean equivalent of the
return value is of concern (zero indicates FALSE)
if ($mailer->batchSend($message))
{
echo "Sent\n";
}
else
{
echo "Failed\n";
}

Swiftmailer send e-mail fails

I have this code which I am using to send an email via Swiftmailer.
I tried many things, I tried with Phpmailer aswell and I am not able to send a simple e-mail. I also tried with mail() function in php and nothing, I don't have the sendmail configured, so I thought to use one of these libraries.
The code I am using is:
require_once ('lib/swift_required.php');
$message = Swift_Message::newInstance()
//Give the message a subject
->setSubject('Webinar Registration')
//Set the From address with an associative array
->setFrom(array('ami#am.com' => 'FROM NAME'))
//Set the To addresses with an associative array
->setTo(array('ami#am.com'))
//Give it a body
->setBody('My Message')
//And optionally an alternative body
//->addPart('<q>Here is the message itself</q>', 'text/html')
;
//Create the Transport
$transport = Swift_SmtpTransport::newInstance('127.0.0.1', 25);
//Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
//Send the message
$result = $mailer->send($message);
When I debug it, it stops right after the require statement. I am trying to send it via localhost and i don't want to use smtp.
Please any help is appreciated.

Swift Mailer can address be banned for mass mailing?

I need to send over 2000 mails and I am using Swift Mailer library for it.
We have own server and it has both SMTP and sendmail transports. I am using SMTP:
$transport = Swift_SmtpTransport::newInstance('localhost', 25);
All mails are send fine to few people, but I'm afraid that we will be banned when we send mass mail.
I don't really know what means "banned" and how it looks like, but I'm afraid about the aftermath.
So, is it true, that such "ban" exists and how to implement mass mailing with Swift Mailer in a right way?
P.S.: My code looks like:
// Create the Transport
$transport = Swift_SmtpTransport::newInstance('localhost', 25);
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
// Create a message
$message = Swift_Message::newInstance($message_theme)
->setFrom(array($sender => $name))
->setTo($emails)
->setBody($message_text,"text/html")
;
try {
// Send the message
$result = $mailer->send($message);
}
catch(Exception $e) {
echo "Error: ".$e->getMessage();
}
As I'm hoping you will not use this for spam!!!
Here are some things to do:
try to same different Emails (change name of the recipient in body)
send emails once every 3-4 seconds and not 100 emails/second - it should send 2000 emails in about 2-3 hours.
Blacklisting/graylisting does indeed exist and there are some best practices you can implement to try to avoid these issues. For 2,000 emails, as long as your headers are legitimate, there is nothing fishy going on in your body text, and your recipients are on different domains, you should not run into this issue. However, as khomyakoshka mentions, the above code is incorrect and you should use a loop to send each email. This avoids exposing your entire mail list to each user.
Some additional best practices:
1) Swiftmailer offers plugins (http://swiftmailer.org/docs/plugins.html) that will help you send bulk email. Of particular note are the Throttler and AntiFlood plugins.
2) If you intend on modifying the contents of the mail to tailor to the recipient, consider using the Decorator plugin (also mentioned on the plugins page) for this task.
Hope these tips help.

PHP mail() function replacement?

When I change providers I always have to make sendmail work and it's a real drag.
Are there any free providers I can use within my PHP code to send the same variables like keycodes for registration verification and stuff?
I tried looking on Google but I only found stuff that had form generators, which is not what I need.
I use PHPMailer with great success.
Right now Swift Mailer is one of the best mail solutions around for PHP. It's highly modular and can easily be configured to suit your needs. You could define multiple transports (in a config file for example) and use the one you need when you change providers.
Here is an example from the docs:
require_once 'lib/swift_required.php';
// Create the Transport
$transport = Swift_SmtpTransport::newInstance('smtp.example.org', 25)
->setUsername('your username')
->setPassword('your password')
;
/*
You could alternatively use a different transport such as Sendmail or Mail:
// Sendmail
$transport = Swift_SendmailTransport::newInstance('/usr/sbin/sendmail -bs');
// Mail
$transport = Swift_MailTransport::newInstance();
*/
// Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
// Create a message
$message = Swift_Message::newInstance('Wonderful Subject')
->setFrom(array('john#doe.com' => 'John Doe'))
->setTo(array('receiver#domain.org', 'other#domain.org' => 'A name'))
->setBody('Here is the message itself')
;
// Send the message
$result = $mailer->send($message);
What you need is an outgoing authenticated SMTP server so your not using the hosts one and don't have to change the details each time.
Take a look at AuthSMTP (there are lots of other websites that provide this) and then use something like PHPMailer or Swift Mailer to send the email with authentication.
The problem is that a lot of ISPs block connections on port 25 (default smtp) to servers other than their own. Has to do with spam blocking etc.

PHP Sending mass mails: One for each or one for all?

When sending mass mails with PHP, is it better to send each subscriber an e-mail (running a for loop through all the e-mail addresses) or is it better to just add all in BCC in a comma separated list and thus sending only one e-mail?
Thank you.
There's a good chance the number of addresses in the BCC field is limited on the SMTP server (to avoid spamming). I'd go with the safe route and send an e-mail to each individual subscriber. That will also allow you to customize the e-mail for each subscriber if needed.
Also note that mail() is probably not the best way to send bulk mail (due to the fact that it opens a new connection to the SMTP server each time it's invoked). You may want to look into PEAR::Mail.
Best practice is to send an email per recipient.
If it's a linux mail server, it can handle massive throughputs so volume should not be an issue unless it's a crap server!
If it's a shared webserver your host may not be happy - if this si the case I'd split it into chuncks and spread the send. If it's dedicated then do as you will :)
If the sending process for some reason failed (example cause might me unresolvable domain) for one of the BCC recipients, the whole operation would be canceled (which is in 99% of cases unwanted behavior).
I you send the emails in a PHP loop, even if one of the emails fails to send, other emails will be sent.
As the others says one mail per recipient is the better fit.
If you want a library to do the dirty job for you, give a try to SwiftMailer http://swiftmailer.org
Here is an example directly from the docs:
require_once 'lib/swift_required.php';
//Create the Transport
$transport = Swift_SmtpTransport::newInstance('localhost', 25);
//Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
//Create a message
$message = Swift_Message::newInstance('Wonderful Subject')
->setFrom(array('john#doe.com' => 'John Doe'))
->setTo(array('receiver#domain.org', 'other#domain.org' => 'A name'))
->setBody('Here is the message itself')
;
//Send the message
$numSent = $mailer->batchSend($message);
printf("Sent %d messages\n", $numSent);
/* Note that often that only the boolean equivalent of the
return value is of concern (zero indicates FALSE)
if ($mailer->batchSend($message))
{
echo "Sent\n";
}
else
{
echo "Failed\n";
}
*/
It also has a nice Antiflood plugin: http://swiftmailer.org/docs/antiflood-plugin-howto

How can I keep track of mail sent using PHP Swift Mailer?

I am using PHP Swift Mailer to send a bulk mail to a set of users. But I am not able to keep track of sent mail.
My code:
<?php
require_once("includes/database.class.php");
require_once("lib/swift_required.php");
$con=DBClass::getConnection();
$db=DBClass::getDatabase($con);
$login_id="myloginname";
$password="mypassword";
$to_mail; //list of people
//Create the Transport
$transport = Swift_SmtpTransport::newInstance('smtp.gmail.com', 465, "ssl")
->setUsername($login_id)
->setPassword($password);
//Create the Mailer using your created Transport
$mailer = Swift_Mailer::newInstance($transport);
//Rate limit to 25 emails per-minute
$mailer->registerPlugin(new Swift_Plugins_ThrottlerPlugin(
25, Swift_Plugins_ThrottlerPlugin::MESSAGES_PER_MINUTE
));
//Create a message
$message = Swift_Message::newInstance($subject)
->setFrom($login_id)
->setTo($to_mail)
->setBody($body,
'text/html'
);
$numSent=$mailer->batchSend($message);
?>
I am using batchSend() method to send mail, which gives me the count of mail that has been sent, but it is not giving me the list of email that has been sent. How can it be possible, is there any plugin or function available?
Using Logger plugin will give me the log, but I am unable to read from that.
You can get an array of email addresses that were rejected by passing a variable by reference to batchSend() for the system to fill in:
http://swiftmailer.org/docs/failures-byreference
Then you can array_diff() those from your $to_mail array to get the succesful ones.
