Unsubscribes & email suppression

Your pre- and post-event emails carry a one-click unsubscribe link (and the header that lets Gmail/Apple Mail show an unsubscribe button). If someone opts out, they see a simple "You're unsubscribed" confirmation — no extra steps.

From then on, that address is automatically skipped on future campaign sends for the event; you don't have to manage a list. This keeps you on the right side of CAN-SPAM.

Note this applies to bulk campaign emails. Transactional messages — like a registration confirmation or donation thank-you — still send, since they're part of completing a purchase.
