    How long should the test duration for an a/b test be?

      I have a email going out tomo to 20K ppl with an a/b test on the subject line.

      I really don't want to wait too long to send out the winner bc I want it to go out tomorrow, not another day (it's related to a launch).

      How long does Marketo wait before it declares an email has not been opened? I suppose that 1 hour might not be enough?

      Thus, is 1 hour enough to reach the sample size of 10%? 

      Thanks!
