Legitimate recruiters don't spam you with emails about possible job fits, they talk with you directly and typically work with you on on only one or two job opportunities at a time.

Apparently McSourcer rebranded and relocated to California. Do your due diligence and look up the address in the email footer.
Tip for consumers: Was solicited for recruiting services, however this is not a legitimate recruiter (based on my personal assessment of their email practices) and appears to have scammed people in the past based on the negative review here and elsewhere.
