You’re absolutely right about this being a huge problem and it’s exactly why I built proper consent management into Fertit from the ground up. What you’re describing (auto-resubscribing after purchase, ignoring unsubscribe requests) is both illegal under CAN-SPAM/GDPR and terrible business practice. The legitimate use case is businesses that actually respect their subscribers. Think GitHub release notes, Substack authors, or local businesses sending monthly updates to customers who genuinely want them. But you’re spot on that too many companies abuse email marketing, which ruins it for everyone.

This is where I definitely appreciate sites/apps/newsletters that have at least a double confirmation (email validation) step before you start seeing garbage.

You'd be surprised how many people don't understand how, say gmail works and just start using an address they never signed up for and now I'm seeing mlb.com receipts for purchases, or someone's student loan paperwork.
