Buttondown: Open Tracking is opt-in
Requirements
Access to the newsletter settings and a test address for technical control of the message sent.
Buttondown describes Open Tracking as an opt-in function. If activated, the email contains a pixel with the email and subscriber ID and an open event is saved. If you don't need individual openings, leave this function disabled.
Check after the change
Check browser memory and network requests and also view web server, proxy, application and provider logs separately. A single product setting does not automatically cover the entire processing chain.
Basis
The general technical differences between opening and click tracking and necessary shipping data are explained in Newsletter without opening and click tracking.
Reset
If the reduced configuration affects a required function, restore only the relevant setting and then recheck data flow, storage, retention and third-party connections.

Important: IP processing is not IP storage
An IP address has to be processed to establish and deliver a network connection. Hosting providers, firewalls or DDoS protection may also process or retain it for a limited time for security purposes. No Logging distinguishes this security layer from unnecessary persistent visitor logging by the website, application and ordinary access logs.
