How do I subscribe or unsubscribe from your emails?

Subscribe using the “subscribe” link in the menu. Emails you receive are only class-related ones. (Including future coupon codes. So you won’t want to miss out.)

But as for any email list for any site on the internet, scroll to the bottom of that email and click on “unsubscribe” or “manage subscriptions” to edit lists or remove yourself entirely. By law, an “unsubscribe” link is mandatory; if a company does not provide that, contact them directly to request removal.
