That's not a marketing line — it's how Cadence is built. There are no open rates, no click maps, no pixels, no analytics, no third-party trackers. A writer will never know whether you opened a letter or clicked a link, because I never collect it. For their sake and yours.
Only what's needed to send you the writing you asked for: your email address, your position in each sequence you've joined, and whether a delivery succeeded. Nothing about your behavior, your device, or your attention.
Every email has a self-service link — pause a sequence, leave one, or unsubscribe entirely, no login and no questions. Leave whenever you like; we'll part as friends.
Cadence sends mail through Resend and stores data on managed infrastructure; those providers see what's technically required to deliver an email, and nothing more.
