the code

// loop store , display values of individual checked checkbox. foreach($_post['check_list'] $selected){     echo $selected."</br>"; } 

seems bit odd me. displays values right, not store them. after loop, $selected have value last element of array. so, nothing stored, comment suggests.

in body of mail, you're using $selected. has arbitrary value array, or uninitialised if array empty. instead implode(', ', $_post['check_list']), joins elements of array commas in between (i.e. [4,7,8] becomes "4, 7, 8").

if still doesn't work, value isn't passed $_post. var_dump($_post) in top of file see if check_list values appear there. can include output of var dump in question if need it.
