Cool, all of your images are getting fetched by the server as it receives and processes the emails. You have 100% open rate on all emails to that domain within 3 minutes of send.

What do you know about the user and their behavior? Nothing. The prefetch is not tied to their actions, therefore you cannot learn anything about their actions.

This post isn't about email open rates, it's about data exfiltration. But for email speficially, show me major providers that prefetch by default.

For data exfiltration, you’re right - this doesn’t help.
