That’s the thing I’ll never understand: why would one have to spam email to be considered not spam?

I wonder at which point it is legitimate to go full conspiracy theory, and suspect they’re just trying to block the little players so they can keep their relative monopoly. Maybe they don’t do it on purpose, but the way their anti-spam measures make life real hard for the little ones sure looks convenient.
