According to the RIR Zonefiles, .nl has a total of 991 network blocks (7
from ARIN, 984 from RIPE) totalling 16488864 IPv4 addresses. The last I
looked, there were only 16.2e6 people in .nl, so that should be no problem,
right? Probably won't work in .an, as LACNIC has only allocated 34816
addresses for 1.8e5 people there.

And that the mail is in English text using only the ASCII character set.

Just one? I'm in the Southwestern USA, which has such good flying
weather that many nations send their Air Force trainees here for
training, and we're used to seeing huge formations of pigs flying
about.
