SquareMeal does not buy email data from third parties to use for its own marketing. 

SquareMeal has been established for over 30 years and over this time millions of people have 'interacted' with SquareMeal and given their email address. There are many reasons SquareMeal would have asked for a user's email address - booking a restaurant on line, signing up for a newsletters, coming to a SquareMeal trade or consumer events, signing up for a competition etc.
