Got another one today:
And if you want to unsubscribe email notification about new vocations let me know and I will delete your email from a Mailing list.
Notice he says he will delete my email from a waiting list, not this particular one.
Apparently this particular job offer is something to do with trails:
During trail-period you will be informed about main vacancy you will pick and your salary will be $1500 USD per every 2 week of trail-term.
