Without a '$' prefix, 'd' is interpreted as a string and not a
variable. There are a few improvements I would make such as
quoting variables and moving the glob (*) into the for statement.
#! /bin/sh
DIR=~/temp/mails
for d in "$DIR/"*
do
if [ "$(find "$d" -type f -print | wc -l)" -eq 0 ]
then
rm -r "$d"
fi
done
