Offkai emails you the essentials — RSVP confirmations, your ticket, refund updates — plus updates from hosts (event changes, reminders).
Every host email has an unsubscribe link at the bottom. Using it on an event's email stops further host updates for that event. You'll still receive the important transactional emails (your ticket, a refund) so you don't miss anything tied to a real order.
For finer control, open Profile → Email preferences (/profile#email-preferences) and switch off whole categories — event reminders, waitlist & spot alerts, payment reminders, host announcements, status updates, or Arigathanks board reminders. Tickets, receipts, refunds, and event cancellations always arrive.
Want host updates again later? RSVP activity re-enables them, or reach out to the host — replying directly to any update email works too.
