Pass a bash array as an argument

I have a bash script in which I’m using an array to get a list of files and I needed to pass the content of this array as an argument, to send an email to some users.

This is the array:

RAW_LIST="$(echo "ls -1 /download")"
declare -a LIST
readarray -t LIST <<<"${RAW_LIST}"

This is how I passed the array to bash:

printf %"s\n"  "${LIST[@]:1}" | /bin/mail -s "$SUBJECT" "$EMAIL"

Trailing :1 in the array will consider all the elements after element [0] as, in this specific case, it'd be ls -1, pretty useless sending it to the user.
