The easy way would install this plugin – https://da.wordpress.org/plugins/contact-form-7/ – It’s super easy to work with, and it will do what you want 🙂
If you don’t want to use a plugin, then you would just code a contact form with html and php.
PHP:
<?php
$firstname = $_POST['firstname'];
$lastname = $_POST['lastname'];
$from = $_POST['email'];
$message = $_POST['textarea'];
$to = "[email protected]";
$subject = "My subject";
$message = "Hello world!";
$headers = "From: " . $email . "\r\n" .
"CC: [email protected]";
mail($to,$subject,$message,$headers);
?>
HTML:
<form action="" method="post">
First name:<br>
<input type="text" name="firstname">
<br>
Last name:<br>
<input type="text" name="lastname">
<br>
Email: <br>
<input type="email" name="email">
<br>
Subject:<br>
<input type="text" name="subject">
<br>
Message:<br>
<textarea name="textarea" id="" cols="30" rows="10"></textarea>
<br>
<input type="submit" value="Submit">
</form>
