How To Change WordPress “from” Email Header

WordPress has wp_mail() function for sending emails via php code. By default, the default WordPress email address looks like WordPress@yoursitename.com. Want to use your real email and username instead? Just use the following code.

This code is pretty easy to implement: Just open your function.php file paste the following code:

	
function res_fromemail($email) {
    $wpfrom = get_option('admin_email');
    return $wpfrom;
}
 
function res_fromname($email){
    $wpfrom = get_option('blogname');
    return $wpfrom;
}

add_filter('wp_mail_from', 'res_fromemail');
add_filter('wp_mail_from_name', 'res_fromname');

How to change WordPress’s default email address and site name

While messing around on a website built in WordPress, I noticed that whenever your WordPress installation emails you, the email address is of the type wordpress@yourdomain.com (in my example it would be wordpress@constantinosorphanides.com) and the sender’s name would be set to “WordPress”.

This was quite annoying and I could not find any straightforward solutions to replacing the default email address (and name) with the ones I wanted. Fortunately, there’s a simple way of changing this:

• Go to your WordPress administration panel
• Select Appearance > Editor
• On the right hand side of your screen you’ll see a column of WordPress files. Locate functions.php and open it.
• At the end of the file, copy and paste the following code, replacing your@email.com and Your Name or Your Website with the ones you want.
• Press Save and you’re done.

	
add_filter('wp_mail_from_name', 'new_mail_from_name');
function new_mail_from($old)
{
    return 'your@email.com';
}
function new_mail_from_name($old)
{
    return 'Your Name or Your Website;
}

If your theme supports custom.php and you decide to use it, make sure that the code above is accompanied by PHP’s opening and closing tags, as such:

	
add_filter('wp_mail_from', 'new_mail_from');
add_filter('wp_mail_from_name', 'new_mail_from_name');
function new_mail_from($old)  
{  
    return 'your@email.com';
}
function new_mail_from_name($old)  
{  
    return 'Your Name or Your Website';
}
