Woocommerce – How to send custom emails based on payment type

Here is the problem. My woocommerce website has 3 different payment options –

• Check Payment
• Western Union
• Cash On Delivery

If my buyer checkout with “Check Payment” I want to send him an automated email that outlines the steps to make a check payment. If he checkout with “Western Union” I want to email him my Western Union information as an automated email. Another automated email should be send for Cash On Delivery.

Usually in Woocommerce you have a single email sent to customer for all completed orders, in my case I need 3 different emails depending on the payment option.

So I started using this tutorial to make a custom email – https://www.skyverge.com/blog/how-to-add-a-custom-woocommerce-email/

The tutorial above is used to make custom emails for expedited shipping. This is the line of code used for the same from the tutorial –

// bail if shipping method is not expedited
if ( ! in_array( $this->object->get_shipping_method(), array( 'Three Day Shipping', 'Next Day Shipping' ) ) )
    return;

What will the line of code be if I want to check what the payment method is? I want to check if the payment method is “Check Payment” so that I can send him a custom email.

Please let me know if you have any idea.

You can send a different customized email for each payment method with this custom function using thank_you hook. There is many options that you can set, for this refer to wp_mail() function code reference.

Here is the code:

add_action( 'woocommerce_thankyou', 'wc_cheque_payment_method_email_notification', 10, 1 );
function wc_cheque_payment_method_email_notification( $order_id ) {
    if ( ! $order_id ) return;

    $order = wc_get_order( $order_id );

    $user_complete_name_and_email = $order->billing_first_name . ' ' . $order->billing_last_name . ' <' . $order->billing_email . '>';
    $to = $user_complete_name_and_email;

    // ==> Complete here with the Shop name and email <==
    $headers = 'From: Shop Name <[e-mail]>' . "rn";

    // Sending a custom email when 'cheque' is the payment method.
    if ( get_post_meta($order->id, '_payment_method', true) == 'cod' ) {
        $subject = 'your subject';
        $message = 'your message goes in here';
    }
    // Sending a custom email when 'Cash on delivery' is the payment method.
    elseif ( get_post_meta($order->id, '_payment_method', true) == 'cheque' ) {
        $subject = 'your subject';
        $message = 'your message goes in here';
    }
    // Sending a custom email when 'Western Union' is the payment method.
    else {
        $subject = 'your subject';
        $message = 'your message goes in here';
    }
    if( $subject & $message) {
        wp_mail($to, $subject, $message, $headers );
    }
}

This code goes in functions.php file of your active child theme (or theme) or also in any plugin file.

This is tested and it works.

Getting your available payment methods slugs (temporary, just to get all slugs). This will display your available payment methods slugs on shop page or in product pages too. After usage, just remove it.

Here is that functional code:

function the_available_payment_gateways(){
    foreach(WC()->payment_gateways->get_available_payment_gateways() as $payment_gateway)
        echo '<div style="border:solid 1px #999">Method Title: "'.$payment_gateway->title .'" / Method slug: "'.$payment_gateway->id .'"</div>';
}
add_action( 'woocommerce_before_main_content', 'the_available_payment_gateways', 1 );

This code goes in function.php file of your active child theme (or theme). Remove it after usage.
