Working on the inactive user mod. Can't figureout mistake
 

I'm working on improving the inactive user mod. But I can't figure out a mistake I prolly made in the new update. So I want someone to check it.

when running it with reminder_count on it should pick the count of emails out of the DB and check if the max emails is already is send. if not it should send the email.

The checking and updating goes fine with the while statement. But when he's going to send with the while statement it doesn't work resulting in this message:


While it should be this:
This is the result with reminder_count disabled.

Can someone review my code because I'm clearly missing something.
