My email address leaked.
I have a relatively new email address that has never been on any spam lists, and I receive zero spam. However, recently PhilippinesFlowerShop.com has started sending me emails suggesting I buy flowers in the Philippines (I was never been a customer there before). How do they know that I bought flowers in the Philippines and got my email address? Either someone has hacked cebugift.com and got my email address, or one of their employees has sold a list of customers. So, either avoid this shop, or use a fake email address when ordering there.
