Direct QSL cards with self-addressed envelope and enough return postage (2$ of the world)
are answered directly (usually within a week).
If no return postage and self-addressed envelope is included then direct QSL cards are answered via bureau. Bureau cards are answered via bureau. I send out bureau cards about 2-3 times a year.
