Using exit in For Loop - Is this acceptable

Hi Folks -

Here is a for loop I've created and I just wanted to see if this was okay practice:

Code:
for M in NAME1 NAME1 NAME3
do
    echo "Executing MaxL:" $M >>${_LOGFILE} 2>&1
    . ${_STARTMAXLPATH}startmaxl.sh ${_MAINPATH}${_MAXLPATH}$M.mxl 
    
    _RC=$?
    if [ $_RC -eq 0 ]
    then
        echo "$M : Successful" >>${_LOGFILE} 2>&1
        continue
    fi
        echo "Encountered Error in MaxL: $M" >>${_LOGFILE} 2>&1
        echo "Exiting Shell Session" >>${_LOGFILE} 2>&1
        echo  | mail -s "Encountered Error in MaxL: $M" z@z.com
        exit
done

echo "${_SN} has completed with no errors" >>${_LOGFILE} 2>&1
exit

Essentially, I want to exit entirely if my NAME*.mxl script returns a failure code. Therefore, I've added an exit in that section. Is this okay?

Thanks!
