This organisation will send you an unsolicited email because it picks up your search of ESL jobs from your computer. You should avoid them. Yes, a so-called person called, Joyce will write to you urging you to pay, or at least urging you to make a 'package' selection. Unless they say in writing that they 'guarantee' a placement, then avoid them like the plague. I sent them three requests for contact and all I got was more emails urging me to pay. My advice, be blind and stupid or avoid them like the plague. Perhaps the fact that they have no contact details - address or telephone number is an indicator that this is a complete scam for idiots.
