Custom message depending on the sum of all the amount purchased by an user

Question

In my effort to improve this code I would like to make it work depending on the sum of all purchases a user has made until then. That is to say, if the whole quantity is less than <100€ send a kind of email, if it is between 100€-200€ another one and if it is more then >200€ another different.

Here it is the code:

add_action( 'woocommerce_email_before_order_table', 'completed_order_mail_message', 20 );
function completed_order_mail_message( $order ) {

    // Getting order user data to get the user roles
    $user_data = get_userdata($order->customer_user);

    if ( $order->post_status == 'wc-completed' && in_array('customer', $user_data->roles) )
        echo '<h2 id="h2thanks">Get 20% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More</strong>" to receive a 20% discount on your next purchase! Click here to continue shopping.</p>';
}

How can I achive it?

Thanks in advance.

You could try something like this:

add_action( 'woocommerce_email_before_order_table', 'completed_order_mail_message', 20 );
function completed_order_mail_message( $order ) {

    // Getting order user data to get the user roles
    $user_data = get_userdata($order->customer_user);

    $user_total_calculated = 0;

    // Get all current customer orders
    $customer_orders = wc_get_orders( $args = array(
        'numberposts' => -1,
        'meta_key'    => '_customer_user',
        'meta_value'  => $order->customer_user,
        'post_status' => 'wc_completed'
    ) );

    // Iterating and summing all paid current customer orders
    foreach ( $customer_orders as $customer_order )
        $user_total_calculated += get_post_meta($customer_order->ID, '_order_total', true);

    // After this you can now set your 3 conditions displaying 3 different notices or custom message
    if ( $order->post_status == 'wc-completed' && in_array('customer', $user_data->roles) ){

        if (100 >= $user_total_calculated)
            echo '<h2 id="h2thanks">Get 5% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More5</strong>" to receive a 5% discount on your next purchase! Click here to continue shopping.</p>';

        elseif ( 100 < $user_total_calculated && 200 >= $user_total_calculated )
            echo '<h2 id="h2thanks">Get 10% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More10</strong>" to receive a 10% discount on your next purchase! Click here to continue shopping.</p>';

        elseif ( 200 < $user_total_calculated )
            echo '<h2 id="h2thanks">Get 20% off</h2><p id="pthanks">Thank you for making this purchase! Come back and use the code "<strong>Back4More20</strong>" to receive a 20% discount on your next purchase! Click here to continue shopping.</p>';

    }

}

This code should work

Code goes in function.php file of your active child theme (active theme or in any plugin file).
