No, not really, we are using one the most expensive offerings in Switzerland. Renting dedi servers for spamming would be not only extremely expensive, they would kick you right away if they noticed. As i said we did nothing wrong, used monitoring and our invoice emails would sometimes end in the spamlist for microsoft, after trying to get it right i gave up and hooked mandrill. if you are runnig some random internet forum, some part of your notifications ending in spam is not a big deal, but for us, invoices ending in spam box is not something you can ignore.
