1. [TRFW_ORDER_NUMBER]:
   • This shortcode is typically used to insert the unique order number associated with a customer’s purchase. It helps personalize messages by referencing a specific transaction or order, making the communication more relevant to the recipient.
2. [TRFW_CUSTOMER_FIRST_NAME]:
   • This shortcode is used to insert the first name of the customer or recipient. Addressing someone by their first name can make the communication feel more personal and friendly, increasing the chances of engagement.
3. [TRFW_CUSTOMER_LAST_NAME]:
   • Similar to the first name shortcode, this one is used to insert the last name of the customer or recipient. Including both first and last names can further enhance the personalization of the message.
4. [TRFW_CUSTOMER_EMAIL]:
   • This shortcode is used to insert the email address of the customer or recipient. While it may not be visually displayed in the final message (for privacy reasons), it can be helpful for internal tracking or reference.
5. [TRFW_CUSTOMER_DETAILS]:
   • This shortcode likely refers to a more comprehensive set of customer details, which could include various pieces of information like the customer’s shipping address, phone number, or any other relevant data. Using this shortcode allows you to insert a block of personalized information into your messages, providing a richer and more tailored experience.

I cannot offer you extensive help in terms of modifications but can offer billed hours.

The general support deals with installation of the plugin, issues come from the plugin itself Bug Fixes, and Small Modifications which means, one or two lines of code I will provide if needed.
