When I add a product to a waiting list that’s out of stock, I receive a confirmation email. Even if I don’t click the “Confirm waiting list” link in the email, my email address is added to the list of those waiting for products.
I think I’ve been misunderstood. When I sign up for the waiting list, even if I don’t click the confirmation link in the email, the email address I added is still added to the waiting list on the site. Even if I enter an invalid email address, it still adds it to the list.
Sorry to hear about the inconvenience. Kindly, please share your Site WP-ADMIN Login details in the Private Content field so that we can check this concern on your Site and help you out accordingly.
I have tested this on our test site. This is the expected behavior of the Waitlist feature. The email address is added to the waitlist immediately after submitting the form. The “Confirm subscription” email does not prevent the address from being saved — it only confirms the subscription for notification purposes.
