How to Add Information to WooCommerce Emails

Adding Information

WooCommerce emails include each line item in an order by default within an “order items” table. This table is automatically included in almost every WooCommerce transactional email, and displays the product quantity, price, and total.

However, this isn’t the only data that WooCommerce has available for the order items table in its emails. There are actually other pieces of product data that can be included, but they’re “turned off” by default. WooCommerce can include information like the SKU and product image very easily by switching the defaults for these pieces of data to “on” instead, letting you add more information to WooCommerce emails.

Add Product Images to WooCommerce Emails

WooCommerce includes the ability to add your product images to the order items within your shop’s transactional emails, and turning them on is possible via filter.

We’ll need to use the woocommerce_email_order_items_table filter to change which data is included in the order items table. This filter lets us change the default values for the items in the “Email Order Items” template so that we can make changes like turning SKUs on or turning on product images.

This filter passes in all of the default values for the email order items table. SKUs, purchase notes, images, and download links are all set to false (“off”) by default. WooCommerce conditionally handles turning some of these on itself, such as download links when downloadable access should be granted, but SKUs and images will need to be turned on manually.

Let’s first enable product images within our email order items template. We can do so my taking the data passed into this filter and returning it, but changing the show_image value to true instead with this snippet (in a custom plugin or functions.php):

 

// Edit order items table template defaults
function sww_add_wc_order_email_images( $table, $order ) {
ob_start();
$template = $plain_text ? ’emails/plain/email-order-items.php’ : ’emails/email-order-items.php’;
wc_get_template( $template, array(
‘order’ => $order,
‘items’ => $order->get_items(),
‘show_download_links’ => $show_download_links,
‘show_sku’ => $show_sku,
‘show_purchase_note’ => $show_purchase_note,
‘show_image’ => true,
‘image_size’ => $image_size
) );
return ob_get_clean();
}
add_filter( ‘woocommerce_email_order_items_table’, ‘sww_add_wc_order_email_images’, 10, 2 );

 

When this code is used, a 32px by 32px product image is automatically inserted in the order items table with WooCommerce emails:

This snippet could also be edited to change the image size. Rather than including $image_size for this value, we can pass in an array of sizes. The first number in the array will be the width, then the second number is the image height (it’s best if you keep the aspect ratio for your product thumbnails, which is probably 1:1).

Let’s change the image size to 150px by 150px instead of the default 32px by 32px. Change:

'image_size' => $image_size

to

'image_size' => array( 150, 150 )

This will give us larger images in the order items table within emails:

This can let you show a picture to customers side by side with the product name in emails to confirm the purchase.

Add Product SKUs to WooCommerce Emails

Product SKUs can also be turned on easily within emails using the same snippet. If you enable SKUs within the email order items table, they will display as #sku (the hash before the SKU will always be shown).

To enable SKUs, you’d change:

'show_sku' => $show_sku,

to

'show_sku' => true,

When SKUs are enabled, they’re added right after the product name.

Notice that I’ve kept images enabled here, but you don’t have to do so — leave the snippet as

'show_image' => $show_image,

instead of

'show_image' => true,

if you don’t want to show images.

As a final note on adding SKUs to emails, I dislike that they’re shown in line with the product name. We can use the woocommerce_order_item_name to adjust the product name and add a line break after it easily:

function sww_edit_order_item_name( $name ) {
    return $name . '<br />';
}
add_filter( 'woocommerce_order_item_name', 'sww_edit_order_item_name' );

Replace your WooCommerce emails

If you want to have more control over your order email design, use an email builder to create emails, including product images and names instead:

Adding Information to WooCommerce Emails

While adding other information to your WooCommerce emails is possible, it requires more advanced customization to do so. These pieces of data are already included in the emails and are simply turned off by default. Our code snippets turn them on for email order items tables.

You can also change the way emails look without changing any of the code around emails by using the WooCommerce Email Customizer plugin.

I wouldn’t recommend changing the 'show_download_links' default, as WooCommerce handles this for you based on your settings (and only includes them with processing and/or completed order emails). However, you could also include purchase notes if desired.
