What we store (and what we never do).

Subject, recipients, send time, open events. Zero message content — not the body, not attachments, not even a preview.

For every tracked email, MailViewed keeps exactly three things about the message: the subject, the recipients, and the send time — plus the open/click events that happen afterwards. That's the complete list.

We never store

  • The body of your email — not even a preview or first line
  • Attachments — during a Compose send they exist in memory only for the seconds it takes Gmail to accept the email
  • Your inbox, drafts, or any email you didn't choose to track
  • Reader locations — we don't geolocate opens

During a Compose send, your message transits our server encrypted (AES-256-GCM) purely to be handed to Gmail, then is hard-deleted. Every claim here is spelled out in the Privacy Policy and Security page.

Skeptical? Good. Open your browser's DevTools Network tab and send a tracked email from Gmail — you'll see the request carries the subject, recipients, and links. No body field exists in the payload.

Did this answer it? If not, email support — a human replies, usually within a day.
