what makes 2nd class stamped mail slower to deliver than 1st class?

Question

Are there physically 2 ways to process the same mail in sorting offices, one is just slower? And what makes the 2nd class process actually cheaper?

Answer 1

Based on terminology, I’m assuming you’re in the UK. There used to be two different handling processes, there isn’t anymore. 2nd class is bulk mail that’s generally pre-stamped and mailmarked so it’s easier (and hence cheaper) for the postal system to handle.
