Email requested Cards are still the most popular and I would encourage anyone to request a card (either Direct or Bureau) by the On-line Qsl Request System (OQRS). It cuts the normal bureau time down by half and will save years – literally. Not only that, the station may not even require a card from you so check first and you’ll save wasting both your own card and your time by using this method.
