Stop comment notifications for reviewers without Articulate ID

Hi everyone,

I've sent a review 360 link to coworkers who do not have Articulate IDs. They have commented extensively on my course and I've been answering them so everyone is kept in the loop about changes and can discuss.

However, I've received several complaints from coworkers receiving a large amount of notifications for comments (makes sense, we've been discussing a lot in the comments section).

Now, even though there is a link at the end of the email they can click to unsubscribe/change settings for notifications, they are then asked to log in. Since they do not have an Articulate ID, this is not possible and they end up having to delete every single notification email.

Is the only way to unsubscribe from notifications to register with Articulate? Or is there some other, simpler solution available?
