You could do the whole thing in one awk program:
Code:
awk '
        NR == FNR {
                A[$1] += $3
                next
        }
        {
                E[$1] = $2
        }
        END {
                for ( k in A )
                {
                        if ( A[k] > 25 )
                        {
                                cmd = "echo message body | mailx -s 'subject' " E[k]
                                system ( cmd )
                        }
                }
        }
