With the ongoing shift from CCST (credit card sized tickets) to PRT (paper roll tickets) or E tickets, I have been surprised to receive CCST when ordering tickets by post recently from c2c, Chiltern Railways, GWR (the old website) and Trainline. (Trainline even issued them in the pre-2014 format, almost making the booking fee I had to pay worth it!) I do see, however, that Southeastern's website states they will post "a printed E-ticket" (link below). Have any other postal issuers switched? Or is postal issue still mainly CCST? (I don't want to pay postal fees to buy tickets from every website to check!)

The full postal e ticket section from the Southeastern website: "eTickets are now also available through the post. If you selected a ticket where an eTicket is available and you choose to have it delivered by post, you will receive it as a printed eTicket ready to use for your journey. Just scan the barcode on the reader at the gate (where available)."
