The webhook does not trigger when a user unsubscribes from the marketing status via email

Hello.

I am having trouble with the following issue regarding webhooks.

Issue
Even if you unsubscribe from the ‘Stop Delivery’ in the body of the email delivered by [Campaigns], the webhook does not trigger.

However, when unsubscribed from the PipeDrive screen, the webhook does trigger.

Thank you for your assistance.
