Well, it's obvious why you never got E-mail 'cause you are actually checking the exit status of echo command which is giving 0 and the first if block gets executed.
Plus I do not understand why you used extra done and fi. Anyways, below is the code I wouls used for the same purpose (I have not tested it though ). See if this works for you:

mktemp
MKTEMP(1) BSD General Commands Manual MKTEMP(1)NAME
mktemp -- make temporary file name (unique)
SYNOPSIS
mktemp [-d] [-q] [-u] template
DESCRIPTION
The mktemp utility takes the given file name template and overwrites a portion of it to create a file name. This file name is unique and
suitable for use by the application. The template may be any file name with at least 6 of 'Xs' appended to it, for example /tmp/temp.XXXXXX.
The trailing 'Xs' are replaced with the current process number and/or a unique letter combination. The number of unique file names mktemp
can return depends on the number of 'Xs' provided; six 'Xs' will result in mktemp testing roughly 26 ** 6 combinations.
If mktemp can successfully generate a unique file name, the file is created with mode 0600 (unless the -u flag is given) and the filename is
printed to standard output.
OPTIONS
The available options are as follows:
-d Make a directory instead of a file.
-q Fail silently if an error occurs. This is useful if a script does not want error output to go to standard error.
-u Operate in ``unsafe'' mode. The temp file will be unlinked before mktemp exits. This is slightly better than mktemp(3) but still
introduces a race condition. Use of this option is not encouraged.
RETURN VALUES
The mktemp utility exits with a value of 0 on success, and 1 on failure.
EXAMPLES
The following sh(1) fragment illustrates a simple use of mktemp where the script should quit if it cannot get a safe temporary file.
TMPFILE=`mktemp /tmp/$0.XXXXXX` || exit 1
echo "program output" >> $TMPFILE
In this case, we want the script to catch the error itself.
TMPFILE=`mktemp -q /tmp/$0.XXXXXX`
if [ $? -ne 0 ]; then
echo "$0: Can't create temp file, exiting..."
exit 1
fi
Note that one can also check to see that $TMPFILE is zero length instead of checking $?. This would allow the check to be done later one in
the script (since $? would get clobbered by the next shell command).
