Lets face it most scams on the internet come fron no reply mail boxes. If i get an email advertising anything i reply to it, if i get a no repky or message cannot be sent i write it off as a scam and delete it
Walmart sends these emails all the time. So in my book poor company to do business with.
Opt out? Thats how scammers getting you to click..
TopResume uses a classic bait and switch on ZipRecruiter. The email says the have job openings, but, when you open the email it's an offer to review your resume.
If they resort to classic scam to get your resume how good can their service really be?
