For the "placed order" flow, there should be the option of a delay, as in many cases the payment method changes shortly after the order has been placed, e.g. because purchase on account is declined or the customer changes their mind.

In these cases, the order confirmation has already been sent via this flow and the mail therefore contains the wrong payment method.

Also very important if there are different e-mail templates for the different payment methods. Here too, this often leads to a problem, which could be solved by a delay.
