Hello there,

Thank you for reaching out to us.

Amelia can't cancel any appointments on its own. If the appointments were not canceled manually by the client, yourself, another admin, or any Amelia Managers (if you're the only employee, I don't know if you have any managers or other administrators on the site) the only other option that's left is a link checker. It looks like this:

What link checkers do is they validate each URL that's in the email, and in order to do that they have to visit the URL. Those can be built into the end user's mailing platform, or they could be add-ons for the browser or the email provider (Gmail, Yahoo, Outlook, etc). When they visit the cancelation URL (to check for potential viruses), they cancel the appointment. Unfortunately, there's nothing we can do in this case. The only workaround would be to create a Front-end Customer Panel and explain the procedure in the email, like:

"To cancel your appointment, please log in to your Customer panel, and click on the pencil symbol. There you'll see the "Cancel" option."

Hope this helps.
