Cried every marketer in history when individuals, groups, or governments implemented rules to make it hard to reach people.

Conversely, think of it from the perspective that those 1% of users are fed up with receiving marketing emails, and the result is that they are taking the measure they feel is effective to reduce the amount of spam they receive.

Look in the mirror. If you are attacking the intelligence of your users because they are doing the best they can with the limited tools that advertising driven companies use to manage their email, it may be worth taking some time to reflect on why that is. You want to send marketing email; you opted to use a cheaper service that has documented considerations for reputation impact. You know the correct solution, you just think you are entitled to a lower cost service to get your product in front of other people. You aren't, and it isn't the users who are the problem, it's the ecosystem.
