Many learners have the same question how can we send multiple emails using PHPMailer Class with email validation. In this example, I am going to tell you how you can validate email on user-end as well as a back-end, and send email to multiple recipients. Follow the tutorial step by step to accomplish the task.

We will use bootstrap for front-end design and PHP as a server-side language.

Step 1.

First we need to create a directory structure.

Create a folder with a name send-emails in this folder create following.
1. Create a folder name class.
  - Download PHPMailer class and place into it class folder. [Download].
2. Create a folder name ajax.
  - In ajax folder create a file with the name action.ajax.php
3. Download Bootstrap Lib [Download Link] or include using CDN.
4. Create a file with extension .php and name index.php.

We use CDN to install bootstrap 4 and JQuery and other JQuery Plugins.
And we use Summernote WYSIWYG a text editor and Google Recaptcha V2

Step 2

Open index.php file in any IDE or in a notepad and past below snippet.

<!doctype html>
<html>
<head>
<meta charset="utf-8">
    <title>Validate Emails and send using PHPMailer and JQuery Ajax</title>
    <link rel="stylesheet" href="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/css/bootstrap.min.css" integrity="sha384-GJzZqFGwb1QTTN6wy59ffF1BuGJpLSa9DkKMp0DgiMDm4iYMj70gZWKYbI706tWS" crossorigin="anonymous">
    <link href="https://cdn.jsdelivr.net/npm/summernote@0.8.11/dist/summernote-bs4.min.css" rel="stylesheet">
    <script src="http://code.jquery.com/jquery-1.12.0.min.js"></script>
</head>

<body>

    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.14.6/umd/popper.min.js" integrity="sha384-wHAiFfRlMFy6i5SRaxvfOCifBUQy1xHdJ/yoi7FRNXMRBu5WHdZYu1hA6ZOblgut" crossorigin="anonymous"></script>
    <script src="https://stackpath.bootstrapcdn.com/bootstrap/4.2.1/js/bootstrap.min.js" integrity="sha384-B0UglyR+jN6CkvvICOB2joaf5I4l3gm9GU6Hc1og6Ls7i6U/mkkaduKaBhlAXv9k" crossorigin="anonymous"></script>
    <script src="https://cdn.jsdelivr.net/npm/bs4-summernote@0.8.10/dist/summernote-bs4.min.js"></script>
</body>
</html>

In the above snippet, you can see we add CDN links into a <head> tag. After that, we design form use below code to create a form with email, subject, and text area field. Copy below code after the body tag.

<div class="container">
    <div class="col-sm-12"> 
        <div id="emailMsg"></div>
        <form id="emailFrom" method="post" onsubmit="return false;">
            <input type="hidden" name="sendEmail" value="ok" />
            <div class="form-group">
                <label>To:</label>
                <input type="text" name="to" id="to" class="form-control-lg form-control" placeholder="More than one email, Please seperate with comma (,)" />
                <div class="text-danger"><small>* More than one email, Please seperate with comma (,)'</small></div>
            </div>
            <div class="form-group">
                <label for="staticEmail">Subject:</label>
                <input class="form-control form-control-lg" id="subject" name="subject" placeholder="Enter your subject" type="text" required="required">
            </div>
            <div class="form-group">
                <textarea name="mailEditor" id="txtEditor"></textarea>
            </div>
            <div class="form-group">
                <button type="submit" name="submit" class="btn btn-primary">Send Email</button>
            </div>
        </form>
    </div>
</div>

Now we need to handle form submission and validate emails on the user end. For that use below script. Past this script just before <div class=”container”>

<script>
	$(document).ready(function(e){
		$("#emailFrom").on("submit",function(){
			$("html, body").animate({scrollTop: 0}, 1000);
			email = $("#to").val();
			if(email!=""){
				totalEmail = email.split(',');
				countEmail = totalEmail.length;
				flag = 0;
				noEmails = '';
				for(i=0;i<countEmail;i++){
					if(emailValidate(totalEmail[i])===false){
						var elements = [totalEmail[i]];
						var noEmails = elements.join(',');
						$("#emailMsg").html('<div class="alert alert-danger"><i class="fa fa-fw fa-exclamation-triangle"></i> Email(s) typo error ('+noEmails+') <strong>Please type correct email(s)!</strong></div>');	 
						flag = 1;
					}
				}
				if(flag==1){
					$("#eMsg").html('<small><em class="text text-danger"> <strong>Example:</strong> example<strong>@</strong>gmail<strong>.com</strong></i></small>');
					return false;
				}
				$("#emailMsg").html('<div class="overlay"><i class="fa fa-fw fa-spin fa-spinner"></i> Please wait...!</div>');
				$.ajax({
					type:'POST',
					url:'ajax/action.ajax.php',
					data:$("#emailFrom").serialize(),
					success: function(data){
						a = data.split('|***|');
						if(a[1]==1){
							$("#emailMsg").html(a[0]);
							$("#to,#subject").val('');
						}else{
							$("#emailMsg").html(a[0]);
						}
					}
				});
			}else{
				$("#emailMsg").html('<div class="alert alert-danger"><i class="fa fa-fw fa-exclamation-triangle"></i> Enter email first <strong>Please type correct email(s)!</strong></div>');
				return false;
			}
		});
                
         $('textarea').summernote({
            height: 300,   //set editable area's height
         });

	});
	
	function emailValidate(email) {
		var regex = /^([a-zA-Z0-9_.+-])+\@(([a-zA-Z0-9-])+\.)+([a-zA-Z0-9]{2,4})+$/;
		return regex.test(email);
	}
</script>

Highlighted code form 24-38 show ajax request that we use to send an email. And the highlighted code form 45-47 show summernote initialization. Now open file action.ajax.php past below code in it.

<?php
include_once('../class/PHPMailer.php');
if(isset($_REQUEST['sendEmail']) and $_REQUEST['sendEmail']!=""){
	$to 		=	explode(',',$_POST['to']);
	$message 	= 	str_replace("\\","", $_POST['mailEditor']);
	
	$message 	.= 	"<br><br>Powered By Learn Code Web <br><br><img src='https://learncodeweb.com/wp-content/uploads/2019/01/logo.png' border='0'><br><br>web : <a href='https://learncodeweb.com' target='_blank'>Learn Code Web</a>";
	
	$mail	= 	new	PHPMailer();
	$mail->CharSet="UTF-8"; // <-- Put right encoding here		
	define("FROM_EMAIL","no-reply@learncodeweb.com");
	define("FROM_EMAIL_NAME",'Learn Code Web');
	$mail->Subject = $_POST['subject'];
	$mail->SetFrom(FROM_EMAIL, FROM_EMAIL_NAME);
	
        $mail->AddAttachment('../uploads/logo.png');
        
	$mail->MsgHTML($message);
	
	foreach($to as $hoemail){
		$mail->clearAddresses();
		$mail->ClearAllRecipients();
		$mail->AddAddress($hoemail);
		if($mail->Send())
			$ms = true;
		else
			$ms = false;
			$noemail[]	=	$hoemail;
	}
	if($ms){
		echo '<div class="alert alert-success"><i class="fa fa-fw fa-thumbs-up"></i> Email sent successfylly</div>|***|1';
		exit;
	}else{
		echo '<div class="alert alert-danger"><i class="fa fa-fw fa-exclamation-triangle"></i> Email not sent to '.implode(", ",$noemail).' <strong>Please try again or type correct email!</strong></div>|***|0';
		exit;			
	}
}
?>

Enter your email and check the functionality. You can enter multiple emails to check the validation of the script.
