I wanted to bring up an important point regarding the subject of the invoice email. The current subject line, "Your Invoice from AMT-X CML GC PTY LTD is Now Available", can be confusing for customers who receive multiple invoices. It would be helpful if the email subject line included the invoice number and customer name to make it easier for customers to identify which invoice they need to check.
