Hi there,
We have checked the issue on your site by subscribing through the plugin’s form.
It looks like info@gitarrenschule.it is being set as a Return-path email header. The plugin sets the Return-path same as the From email. In your case it should be info@natürlich-glücklich.com but sometimes other plugins or theme can modify it. Example screenshot here.
Can you please check for the issue with only the Email Subscribers plugin active? To assists you in the debugging, you can also install and activate Health Check & Troubleshooting plugin which will deactivate plugins only for you without affecting other site users.
After deactivating other plugins, please send some test emails to your email address and check what is the Return-Path header in the received email? If you are using Gmail for receiving test emails, then this article may be useful in how to check the email headers.
Let us know what comes out in your debugging or if you have any further queries.
Thank you.

I did all the tests: I activated the Health Check & Troubleshooting plugin and installed a default wordpress theme. Then I just activated the Newsletter and Subscriber Plugin only and sent the test-emails. In the header is still the wrong email address, see here (Link). I would be grateful if you could help me! Thank you so much!

The issue seems to be a bit strange. We have tried to replicate it in our testing but, somehow it is not getting replicated.
