In that case, I'd probably have a config file that saves each event type along with a timestamp of the last email sent for that type. That could be done with any module that can save key/value pairs in a file. Then, in pseudo-code: 

when there is an event, get the type (A)
if there is a timestamp saved for A
  and if the timestamp is less than 1 hour old
    do nothing
otherwise send an email about A
  and update the timestamp for A with the current time

Do it like that, and you can run your script as often as you like without getting extra emails.
