I've received two today as it happens; one with a quite conversational tone, and the other with a five-point questionnaire. I have to say I quite liked the transactional nature of the second one, it felt more real.

Both were for abnormally low level roles, so perhaps in a few months time they'll be sending me info about jobs wallpapering their warehouses.

Edit: Ick, reading the other comments the pay is higher than I realised for the roles they're suggesting. I'm feeling different an hour later.
