The email with your link to class should come from Zoom. Sometimes emails get caught in spam filters. Please check your spam, junk, or promotions folder to see if the email is there.
The other reason that you may not have received a receipt or link email is due to a typo when inputting your email address during registration. Happens all the time! If you didn’t receive an email with login information, please email firstname.lastname@example.org. The hour before the live session we are preparing for class and may not see your message. If you miss the live class, you will still have access to the replay.
