I guess what's confusing is that I'm calling the promotional emails also "spam".

But thanks for your suggestions.

I see a few problems. When I receive a promotional email, I want to add a rule, and I have to click 7 times (including once for "Archive"), and use the scroll-wheel to select the "Promotions" label. Secondly, the rule is not applied directly. This is confusing, and cumbersome. Note: I don't want to Unsubscribe (because there may be vouchers), and I don't want to mark it as spam, for the same reason.

Another problem is that the amount of rules gets unwieldy this way. I have hundreds of rules already for promotional stuff and the rules I use for other (more important) stuff are hidden between them.

Maybe you think I am complaining too much, but in gmail it was all simple and automatic.
