There was one FEMA test that I submitted and didn't get an email back. I still have my answers circled on my hard-copy of the final exam. Worst case scenario, I figure I may have to submit that one again.
If you have received other certificates, I would doubt that your email is firewalling it or sweeping it to junk-senders or spam-senders lists. If not... that may be something to think about.
