WooCommerce: How to Add CSS to Order Emails

Unlike your WordPress theme, you can’t just add CSS to your style.css in order to customize the look of the WooCommerce emails.

This handy PHP snippet is therefore the only viable solution. It’s a little tricky but once you get the idea adding CSS to Order Emails is actually straight forward.

return $css;

Where to add this snippet?

You can place PHP snippets at the bottom of your child theme functions.php file (before "?>" if you have it). CSS, on the other hand, goes in your child theme style.css file. Make sure you know what you are doing when editing such files - if you need more guidance, please take a look at my free video tutorial "Where to Place WooCommerce Customization?"

Does this snippet (still) work?

Please let me know in the comments if everything worked as expected. I would be happy to revise the snippet if you report otherwise (please provide screenshots). I have tested this code with Storefront theme, the WooCommerce version listed above and a WordPress-friendly hosting on PHP 7+.

  1. Hi Rodolfo,
    Thanks for the snippet. I try to hide a specific table cell with a pseudo class

    table.gfield_list td:nth-child(8) { display:none; }

    , but without success. Any way to achieve this? Thank you

    1. Are you testing on Gmail? I think it doesn’t accept CSS pseudo classes

  2. Hi,

    What if I want to edit the actual HTML of the footer of the WooCommerce email?

    1. Hey Kosta, if you’re referring to the content, you can change that in the WooCommerce > Settings > Emails page

  3. Hi Rodolfo, thanks for all your awesome woocommerce tutorials.
    I have updated the CCS for the woocommerce emails, and everything is being updated with the exception of the actual order item text. ie , the text inside Product, Quantity and price, although the table headers, Subtotal, Shipping , Paymenet method and total are all correct. of course i’ve updated the .td style.

    Its really interesting I’ve added the following

    add_action( ‘woocommerce_email_header’, ‘add_css_to_emails’ );
    add_action( ‘woocommerce_admin_new_order’, ‘add_css_to_emails’ );
    add_action( ‘woocommerce_email_order_details’, ‘add_css_to_emails’ );
    add_action( ‘woocommerce_email_order_items’, ‘add_css_to_emails’ ); // thought this might override the order item
    add_action( ‘woocommerce_email_adresses’, ‘add_css_to_emails’ );
    add_action( ‘woocommerce_email_footer’, ‘add_css_to_emails’ );

    Hope you find this interesting, I am sure you’ve come across this one before 🙂

    1. Thanks so much for your comment Keith!

  4. Thank you for this snippet it works good in ipad and medium screen but the email in the mobile screen look like disappear half of the email?
    what i will do in this case?

    1. Ohoud, thanks so much for your comment! Yes, this is possible – but unfortunately this is custom work and I cannot provide a complementary solution here via the blog comments. Thanks a lot for your understanding! ~R

  5. Thanks for this snippet, it works wonders for simple tweaks!

  6. Could anyone help me to remove the total sum from new order’s email for customer as well as for admin in Woocommerce 3.2.6? Subtotal, Payment method and all other info must stay. I want remove total sum ONLY.

    If it’s impossible, maybe the ease and simple way will be just to set white color for total label and price, so it will not visible? ))) I understand, it’s little bit funny, but it may work.

    Thank you.

    1. Hey David, thanks so much for your comment! Yes, this is possible – but unfortunately this is custom work and I cannot provide a complementary solution here via the blog comments. Thanks a lot for your understanding! ~R

  7. I am trying to insert a table into the woocommerce_email_after_order_table location of the customer completed email. I am getting the table into the section but I want to change the styling. The table is a tablepress shortcode which I am inserting using the do_shortcode function. When I look at the email I see the following:

    Feb. 10, 2018
    Oak Bluff
    7:30 pm - 11:30

    I would like to change the text alignment along with the padding. Is there some way that I can do this?

    1. Sorry, it doesn’t look like the coding came through properly.

      1. No problem David!Maybe you can add CSS to WooCommerce emails with this: https://businessbloomer.com/woocommerce-add-css-woocommerce-emails/

  8. Awesome code find, thank you! I’m wondering why I’m getting a warning though when I add this to my functions? Thank you!

    Warning: Missing argument 2 for add_css_to_email() in /home/xxx/public_html/wp-content/themes/xxx/functions.php on line 421

    1. Hey Sara, thanks for your comment! I tried this again on Woo 3.2.3 and I get no warning. Also on PHP7. Not sure really 🙂

  9. Is there something that need to be changed in snippet 2 in WooCommerce 3.0?
    I cant get it to work :/

    1. Hey Simon, thanks for your comment! Are you using the exact same snippet?

  10. Hello

    Thanks for the great tutorials! They are very helpful. I have a question for you please.

    Why are php start / end tags written in an unusual order?

     if ( $email->id == 'new_order' ) {
    ?> // written near the beginning of the function with no start <?php tag before it
    <?php // written at the bottom of the page after php end tag 
    1. Good question James! So, we’re already in a PHP file and writing a PHP function. The opening PHP tag is already in such file (functions.php), so to echo HTML or CSS we need to close it and then reopen it when we’re finished with the HTML/CSS bit. Does this help?

  11. Hi

    I’m not a coder…

    I would like to print products on the emails in different formats, depending on product category. So like

    All products from category 1 = font=blue
    All products from category 2 = font=red

    and so on.

    How and where do I do this?



    1. Hello Patrick, thanks so much for your comment! You could try to combine this snippet with this other tutorial (https://businessbloomer.com/woocommerce-conditional-logic-ultimate-php-guide/) in order to apply PHP conditionally. Unfortunately this is custom work and I cannot provide a complementary solution here on the blog. If you’d like to get a quote, feel free to contact me here. Thanks a lot for your understanding! ~R

      1. Hi Rodolfo

        Thanks a lot for your reply!!! Great link. I think with this I can work…

        Thanks again


        1. Awesome to hear that Patrick 🙂

  12. Hello,

    First of all, thanks for this! It seems to exist on one place on the internet, and that is here!

    I am having difficulties with the if statement.

    I believe it might be because of the email IDs having changed. Can that be the case?

    Do you know of a list of these email IDs that can be used.

    Most importantly, what should I but if I only want to make a change in customer order complete email.


    1. I think I managed to solve it finally by doing so:

       add_action('woocommerce_email_before_order_table', 'add_content', 20, 4);
      function add_content($order, $sent_to_admin, $plain_text, $email) {
      // Adds CSS to "new order" email only
      if ( $email->id == 'customer_completed_order' ) {
      echo '<br><h2 id="h2thanks">Dela en bild på vår facebooksida!</h2><p id="pthanks">Vi är jättetacksamma om du vill lämna ett par goda ord på vår facebooksida, så andra kunder kan känna sig trygga i sitt köp.<br><br>Dela gärna en bild på vår sida där ni bär era ringar! :)<br><br><a href="https://www.facebook.com/RingsofSweden/" target="_blank">Tryck här för att göra ett inlägg på vår sida!</a></p><br>';
      1. Great, Marcus, thanks for following up! Much appreciated 🙂

      2. Dude, thank you, thank you, thank you. You just solved my week-long search for how to do this. So glad I found your comment.

    2. I had the same question as Marcus (a list of the email IDs) and found them here:

      1. Ah, awesome!
