I'm not sure what "very strong" means, is it referring to the amount of money in which case I'd assume it would read better with a "Low to mid $$$$$" , or the quality of the lead that the enquiry came from, which would mean the feed is manual rather than automated as it would require either an opinion/assessment, or other data such as the enquiring email address has previously made confirmed purchases.
Either way looks like a junk enquiry to me, not surprising anyone there I guess.
