PHP Mail using Gmail SMTP Tutorial

So here is the tutorial for sending PHP Mail using Gmail as your SMTP engine

Alright, this was one of the queries I got a few days back. I finally got the time to pour some time on it.

So here is the tutorial for sending PHP Mail using Gmail as your SMTP engine.

First of you all, I’m going to pretend that you’re familiar with a few things:

  • PHP (you know, PHP: Hypertext Preprocessor). Its a lovely language for developing webpages. If you already knew that, then good. If not, you might want to read a good PHP Tutorial.
  • A local apache+PHP webserver running to test with. I use either XAMPP or WAMPServer, while on Windows Vista. Or install LAMP stack in Ubuntu.
  • Can edit your PHP.ini configuration file. (If you don’t know what I’m talking about, get really familiar with the above two.

K, here goes.

    1. If you haven’t done so already, get a PHP server running.


    1. Download PHP-Mailer (they also have other php software for easy form-to-email).


    1. Go to your C:\xampplite\htdocs folder (in XAMPP) or C:\wamp\www folder (in WAMP), and extract the PHP Mailer into it. I’ll call this folder Root from now on.


    1. Now go to Root\PHP-Mailer\examples\, and open up test_smtp_gmail_basic.php.


    1. Now you shall have to do some minor editing. Don’t worry, its majorly minor. Just change the Emails to your send and receiver, and type your password. Here’s what mine almost looks like. Almost. Thats not the password. … I think.


Open and edit test_smtp_gmail_basic.php
Open and edit test_smtp_gmail_basic.php

$mail->IsSMTP(); // telling the class to use SMTP

$mail->Host       = ""; // SMTP server

$mail->SMTPDebug  = 1;                     // enables SMTP debug information (for testing)

// 1 = errors and messages

// 2 = messages only

$mail->SMTPAuth   = true;                  // enable SMTP authentication

$mail->SMTPSecure = “ssl”;                 // sets the prefix to the servier

$mail->Host       = “”;      // sets GMAIL as the SMTP server

$mail->Port       = 465;                   // set the SMTP port for the GMAIL server

$mail->Username   = ““;  // GMAIL username

$mail->Password   = “topsecretpassword:D“;            // GMAIL password

$mail->SetFrom(‘‘, ‘Vishal Kumar’);

$mail->AddReplyTo(““,”Vishal Kumar”);

$mail->Subject    = “Hey, check out”;

$mail->AltBody    = “Hey, check out this new post on”; // optional, comment out and test


$address = ““;

$mail->AddAddress($address, "Vishal Kumar");


  1. Now, pressing save, you’ll be half done with this little tutorial. Ok, the actual step is you need to edit your PHP.ini file settings. You can find that C:\xampplite\php if you are into XAMPP. Here you need to open the PHP.ini file, then search for “openssl”. Go ahead and take that ‘;’ comment symbol from the start of the line. In WAMP, all you need is your mouse. Just click on the speedometer icon of WAMPServer in the taskbar. Go to PHP>PHP Extensions and click on php_openssl to turn it on
Enable the php_openssl.dll extension by taking off the ';'
Enable the php_openssl.dll extension by taking off the ‘;’ in XAMPP


Tick to enable php_openssl in WAMP
Tick to enable php_openssl in WAMP


    1. Restart your servers services. This should be fairly simple


  1. Go navigate to http://localhost/PHP-Mailer/examples/test_smtp_gmail_basic.php in your browser. And then check your Receivers Inbox. Hi!!!

Thats about it; thats how I managed to send emails using GMail’s SMTP engine to any mail, through PHP.

Note though, this tutorial is meant to be a specific reply to a certain query I got, but I figured more people would want to read this, so I posted it up.

If you have any doubts, or extensions, or any helpful suggestions, comment up. 🙂

hello vishal kumar,

i m trying to install a prog. in my system but after installation when run its index.php then it shows login screen and when i type user name and password which i allready created during installation process it shows wrong user name /password message. i don't know where i m wrong but i think i m doing wrong when third step of installation ask for SMTP server IP address then user name and password.

Hey, what software are you using? It might help if you put the links for it.

And when specifying the STMP address you don't need to put in the IP Address anywhere. Its the thats required. The DNS Servers will send the request to the correct IP Address.

i m using google as a smtp server but still i don’t understand but any world meanig to ask general

hi vishal'
Your tutotial helped me a lot to send mail using smtp authentication in php, am using Xampp1.7.1, while trying to send error i get the following error.

But is didn't work, after they saying that it is bcz of your are using google apps.

Please reply me solution with any example.

I read your tutorial , but, i didn't get it. right

i want to send email from this way but this tutorial is not well explained. can you explain with any example .

Thx man….
this was the best tutorial for sending mail…

it worked like a charm 😉

u r the best 🙂 🙂

Hi Vishal,
Great Tutorial, I have configured everything using your tutorial and the mail gets sent to my gmail account. Just wanted to ask you something, I have created an email form where I want to click on the Send Button and this should send an email to my gmail account, how do I do this? Will be waiting for your reply. Many thanks

In your email Form, you would be making use of the <form> tag and assigning it an action (the PHP mail sending page), and a method (either GET-send the data in the URL address, or POST-send it in the request itself, so it doesn't appear in the URL).

So you'll have <form action="sendmail.php" method="post">…

Then in your sendmail.php, you need to receive the variables.
Access the form elements in the previous page with '$_POST['name']'. So instead of the strings in the demo email sending above, you would use the POST variables.

what you have done is good vishal but I would like to mention that u are no where using standard "mail()" function of PHP which dosen't work unless
1> u send mail from localhost to localhost
2> u have a registered domain on the webspace

anyways nice tutorial…great job

Hi Vishal
I have configured everything using your tutorial and the mail net gets sent to my gmail account.
actually it is not shown any error and not send the mail

Where have you hosted this? Have you started from fresh? You can also enable error messages by setting STMPDebug to 1.

Also check out that your PHP is working by enabling error messages in php.ini (search for error_reporting ), and making sure theres a line like error_reporting = E_ALL

do i need to also make changes at the php.ini at the part below?
[mail function]
; For Win32 only.
;SMTP = localhost
;smtp_port = 25

; For Win32 only.
;sendmail_from = root@localhost

Hi vishal , i have followed instructions above but when i run test_smtp_gmail_basic.php in browser it doesn't display anything and email is not delivered. i am using wampserver 2.0 please help me out.

Are you sure you followed instructions to the letter?
First check that normal php pages are being displayed (i.e. wamp is running as it should). Create a test.php page in your www folder, and put in <?php echo "hi"; ?>
Then open the page by going to your http://localhost/test.php. You should see a "hi".
If you don't, check click on the wampserver logo and select Start All Services.
If you have started the services and you were just thinking that yada yada yada I've already done all of that, please make sure that you've edited the php.ini page.
If even that doesn't work, try using XAMPP, and try with the same instructions.

i tried all your instructions but still getting following error while creating new tickets.
Warning: mail() [function.mail]: SMTP server response: 501 5.5.4 Invalid Address in C:Inetpubwwwrootosticket_1.6.0uploadincludepearMailmail.php on line 128

got this error. can u help me?

SMTP -> ERROR: Failed to connect to server: Unable to find the socket transport "ssl" – did you forget to enable it when you configured PHP? (104113184)
SMTP Error: Could not connect to SMTP host. Mailer Error: SMTP Error: Could not connect to SMTP host.

Hi Vishal, can i use this code to send an email to my gmail account from the website i have host…? if yes, could u tel me the way to do it…?

Hi Vishal,

i m getting following error on my local machine.

SMTP -> ERROR: MAIL not accepted from server: SMTP -> ERROR: RCPT not accepted from server:

Good write up Vishal.
if u intent to send any email to google or yahoo or any major email provider you'll probably need to append a 'return path' (bounce mail address) on the headers <code></code>, otherwise your email might be consider as spam and end up in the spambox. not where it should be. Just my 2cents

Warning: mail() [function.mail]: "sendmail_from" not set in php.ini or custom "From:" header missing in C:wampwwwmailmail.php on line 27
Cannot Send Email

Pls Send me Properly worked file plsssssss

Thanks a lot Vishal Kumar! Your tutorial is really a good one. But please tell me whether it’s the only way of sending mails from localhost in PHP, i.e., when we don’t want upload our site and want to continue testing it on localhost? You know that the mail( ) function is already there in PHP but when I use it, I get this error message:

“Warning: mail() [function.mail]: Failed to connect to mailserver at “localhost” port 25, verify your “SMTP” and “smtp_port” setting in php.ini or use ini_set() in C:\wamp\www\CompleteSite\Copy of MailTry.php on line 9″

When I use ini_set( ) function for setting smtp then I get this error message:

Warning: mail() [function.mail]: SMTP server response: 530 5.7.0 Must issue a STARTTLS command first. y2sm10787087wix.7 in C:\wamp\www\CompleteSite\Copy of MailTry.php on line 9.

Please do reply.
Thanks in advance,

Hi – anyone care to help me write a script for sending emails from “Contact Submission Form” of a website ?

The webhost where i’m hosting does NOT provide PHP sendmail. The support team have suggested in using “Gmail SMTP Service” for sending emails.

The content of the script should include the following :

Use SMTP Server for E-mail: Yes
SMTP Server Address: ssl://
SMTP Server Port: 465
Authentication Method: PLAIN
SMTP username: [Your Gmail or Google Apps E-mail address]
SMTP password: [Your E-mail Account password]

The body of the script should be contained in the following structure;

Thanks in advance.

Simpliest solution:

SMTP4PHP is a collection of PHP classes, dedicated for composing and sending multipart/mixed email messages quickly and easily, with or without embedded images and/or attachments.

$e->to = new User("Receiver's name", '');
$e->subject = 'SMTP4PHP Test mail';
// EXAMPLE: add inline image example
$e->htmlMessage = 'This is a HTML message!addImage('./image.jpg').'" border="0">';
$e->txtMessage = 'This is a TEXT message!';
// EXAMPLE: add attachment example

/* NOTE: ALL emails are sent through the same connection, speeding up transmission. */
try { $smtp->send($e); /* OR $smtp->send($e,$e1,$e2);*/ }
catch(Exception $e) { }


I found this when trying it on my local machine, can you suggest me how to solve it.

Failed to connect to [SMTP: Invalid response code received from server (code: -1, response: )]


I know it was always looking for trouble if you try to use your free Gmail acount as the SMTP server for your web application. I used for tests while writing this tutorial my Google Apps account. The best choice is an alternative SMTP service, Sendgrid is cool and offers a free account as well (enough for smaller applications)

Thanks for the code. I used it and it worked but I’m getting an error along with “message sent” as….
Invalid address: ‘, ‘Message sent!

this is the error i’m gettin. please help. and also tell me how to add cc, bcc in the same code…thank you
