Mass Email SQL Script Error

Just downloaded and tried to install the Mass Email Sender and received the following error when attempting to run the SQL query as instructed ...

Error
There seems to be an error in your SQL query. The MySQL server error output below, if there is any, may also help you in diagnosing the problem

ERROR: Unclosed quote @ 0
STR: "
SQL: "NT=1 ;

SQL query:
"NT=1 ;

MySQL said: Documentation
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '"NT=1' at line 1

Is the fix as easy as closing that quote like this: "NT=1" or should it be single quotes?

Also, I just want to confirm... this sends out individual emails, right? We have 1700+ users and don't want to risk our server getting blacklisted as a spammer. We don't intend to send out regular emails so I don't feel setting up a mailchimp account is necessary. Any feedback is appreciated.
