How RedLetters measures growth

RedLetters uses first-party server-side page-view and subscription attribution records to understand which public pages help readers become subscribers. These first-party records are the source of truth for growth decisions.

RedLetters also uses Google Analytics 4 for aggregate context such as page views and broad traffic patterns. Subscribe analytics events do not include email addresses, and email addresses are not sent to Google Analytics.

Email addresses are used for subscription delivery, preferences, and unsubscribe handling. Private tokenized unsubscribe and preference pages are not meant for search indexing.

Questions, corrections, and privacy concerns can be sent through the contact page.
