I'm looking to add an option to my pages that will allow the user to send out notifications that the post has been added to a subscribe list when they click the button.

I want the button to be on the side of the post edit page.

This page looks like exactly what I want, but it doesn't show how to add my code and make my code executed when the button is pressed.

Here's what I have:

function rt_custom_button(){
        $html  = '<div id="major-publishing-actions" style="overflow:hidden">';
        $html .= '<div id="publishing-action">';
        $html .= '<input type="submit" accesskey="p" tabindex="5" value="send media note" class="button-primary" id="custom" name="">';
        $html .= '</div>';
        $html .= '</div>';
        echo $html;
}
add_action( 'post_submitbox_misc_actions', 'rt_custom_button' );

I put this is a plugin file and the button shows up. When I click it, now it publishes the post if it's not published. But I don't know how to get it to execute this code instead:

function my_custom_email() {

    $to        = 'myuserlist';
    $subject   = 'new post';
    $message   = 'title of post';
    $headers[] = 'From: ' . get_option( 'blogname' ) . ' <[email protected]>';

    add_filter(
        'wp_mail_content_type',
        'my_custom_email_content_type'
    );
    $wp_mail_return = wp_mail(
        $to,
        $subject,
        $message,
        $headers,
        $attachments
    );
    if( $wp_mail_return ) {
        echo 'Mail sent';
    } else {
        echo 'Failed';
    }
    remove_filter(
        'wp_mail_content_type',
        'my_custom_email_content_type'
);

Also, when a user clicks the button it will send email to the user list with the post and featured image if possible as an attachment.

Or if I need to add this to it's own metabox if that would be better.

First of all you need prevent whole post form sending. Try:

function rt_custom_button(){
    $html  = '<div id="major-publishing-actions" style="overflow:hidden">';
    $html .= '<div id="publishing-action">';
    $html .= '<button onclick="send_note(event);" accesskey="p" tabindex="5" class="button-primary" id="custom" name="">send media note</button>';
    $html .= '</div>';
    $html .= '</div>';
    echo $html;
 }
 add_action( 'post_submitbox_misc_actions', 'rt_custom_button' );

Then you need to add JS function somewhere:

function send_note(event){
    event.preventDefault();

    $.post(ajax_url, {
        action: 'send_note'
    }, function(response){
       ...
    });

}
