Openn

Honest email tracking for Gmail: opens and clicks, hosted in Europe, without reading your inbox.

Openn tells you when the emails you send from Gmail are opened, when the links in them are clicked, and how much each signal can be trusted. An open is not always an open. Apple Mail can preload an email before anyone reads it. Corporate security filters open messages and follow links to scan them. Gmail fetches images through its own proxy. Most trackers count all of it. Openn classifies every event and shows you what it actually means: • Reliable: opened by a recipient, counted precisely. • Estimate: opened at least N times, from an email client that caches images. • Apple preloaded: received on Apple Mail, an open can't be confirmed. • Security scan: not opened yet, checked by a security filter. • Not opened yet. Your own opens are never counted. Emails sent to several recipients are marked as global tracking. HOW IT WORKS Write and send from Gmail as usual. A toggle in the compose window turns tracking on or off for each email. When you open a sent email, a banner shows its opens and link clicks. Pro users can also get a Chrome notification when a recipient opens an email or clicks a link. PRIVACY BY DESIGN • Openn never reads your mailbox. It has no access to the Gmail API and only acts on the email you are composing and on the tracked emails you display. • The subject, body and recipients of your emails never leave your browser. • Recipients' IP addresses and User-Agent strings are used for a fraction of a second to classify an event, then discarded. They are never stored. • Data is stored in the European Union. • Sign in with Google uses only your name, email address and account identifier. PLANS Free: open and click tracking, with a short "Sent with Openn" signature in tracked emails. Pro: no signature, your own tracking subdomain, and Chrome notifications. 36 EUR per year or 4 EUR per month, excluding VAT. Openn is for professional use.
