Sendmail command truncating to list

Hey Folks - I'm trying to pass a list of To address using sendmail command but upon executing the script the to list gets truncated and not able to send the last
sender :

-bash-4.3$ ./akt.sh
Date : 03-JUL-18
aaaaa.sss#bgttecre.bom trcikant.shrivas#bgttecre.bom abc#xyz.bom pqr#lmn.bom lion
#tiger.bom tom#jerry.bom
lion... User unknown
#tiger.bom... User address required
/home/asian/dead.letter... Saved message in /home/asian/dead.letter

below is the code snippet :

(
echo "From: "
echo "Subject: testing of html table using awk"
echo "Content-type: text/html"
echo
awk -F "," 'BEGIN{print "<table>"} {print "<tr>";for(i=1;i<=NF;i++)print "<td>" $i"</td>";print  "</tr>"} END{print "</table>"}' $fName
) | /usr/sbin/sendmail $toList_alert


$to_list = aaaaa.sss#bgttecre.bom trcikant.shrivas#bgttecre.bom abc#xyz.bom pqr#lmn.bom lion#tiger.bom tom#jerry.bom
