SendAware is a solution. Unlike most trackers that use a hidden 1x1 pixel image, SendAware uses Google’s own API to detect when, where, and how a recipient opens your email — without adding any external images or scripts that trigger spam filters.

SendAware does not store your emails. All processing happens client-side or via their stateless proxy for API calls.
