I purchased perfume from an online retailer about five years ago (I don't remember exactly when) and had it shipped to me in India. Since then, those powerful data management tools have processed me regularly.
Blue Hornet sends me purchase offers at appropriate times? Oops, no, not before diwali or holi. Instead I get offers just before Christmas (which is not a holiday in India), and summer offers after the end of summer.
Blue Hornet manages its customers' data at all? Obviously not. After five years of not responding, I still get the garbage. I've never replied, I've never clicked on any links in the spam, and still it keeps arriving.
Blue Hornet tailors the message to the recipient? Not even the
message text. There are even stupid things like
Christmas delivery in the USA even though I've never ever ordered
anything to a US address.
And naturally, the way to opt out is to read the spam and follow the spammer's instructions somewhere towards the end.
Still, Blue Hornet is better than some of its competitors. The SMTP MAIL FROM address points to returnpath.bluehornet.com instead of a throwaway domain like bp06.net or ann0.com, I only get one copy of each spam, and that copy is in a language I understand.
