Hi William,
I hope you are doing well. Sorry for not replying to your issue earlier. I have also received an email from you through our ticketing system and have replied there as well, but I am reposting here for your convenience.
I have recorded a video for you showing the steps you need to create a custom email and set it to be triggered when a particular product is included in the order. Additionally, you can refer to this documentation for more details: https://wpfactory.com/docs/additional-custom-emails-recipients/how-to/woocommerce-email-settings/
Please check the video and let me know if you need any further help or assistance.
Best regards,
WPFactory support team
