What does this mean for email marketing?

Mail Privacy Protection prevents email senders from seeing accurate opens and IP addresses, meaning:

  • Open rates are inflated.
  • Open time is unknown.
  • No device data is shared.
  • Geolocation is a mystery.

This impacts everything from measuring email performance to engineering automated nurture flows like re-engagement campaigns.
