How do I identify contacts who have unsubscribed?

There are 2 ways to determine recipients who have unsubscribed:

Analysis of the dashboard 

The dashboard is displayed on the homepage of your Quentn system. In the contact statistics you will see, among other things, how many contacts registered again or also unsubscribed.

Contact overview

Go to your contact overview and filter by email status "unsubscribed". You will now see all contacts that have unsubscribed from your list.
