I assume you have transactional and marketing emails coming from separate email addresses. If the email ecosystem made it easier for bulk senders, this would just shift the burden onto recipients. Right now the common enemy of illegal spammers externalize the costs of their business onto email providers and users. For every dollar they take they impose 100x that in spam filtering costs. >99.9% of raw email traffic is spam. Blame spammers who offer fake unsubscribe links. Or companies who violate CAN-SPAM by requiring login to unsubscribe instead of one click opt-out. Marking as spam always works.
