whenever customers places orders with me, they also submit their email add along with the payment and info. what i plan this xmas season is to backend offer all my customers on a special deal on what i sell, like a special discount or something.

however, on my cehckout page, i do not have that option that customers check whether or not they want to receive offers etc.

my question is that is it okay to send them an email offering them the deal. if it is NOT okay, i will still consider taking the risk of maybe getting into spam folder or something like that for exchange of a couple sales. i am assuming to have around 2,500 customers by december 16, where i will email them.

what do u guys think about this?
