I get regular emails from an online hotel booking agency that I use and recommend a lot. I didn't tick the box saying I didn't want emails, because like everyone else, I'm keen to see bargains. But I quite often just delete the emails because if they come at a time when I know I can't use the offer, or whatever, I don't bother reading them.
I don't consider these spam, nor to be a waste of my time. And it only takes seconds to delete them.
