WHY Because being reachable shouldn’t mean being constantly interrupted. HOW OWL turns interruptions into something you control. You choose exactly which emails are urgent by setting simple rules (senders, domains, keywords, or specific threads) and optional schedules for when those rules are allowed to alert you. WHAT OWL is an alert layer for your existing Gmail/Outlook accounts—not another inbox. When new mail arrives, OWL checks it in the background and sends a push alert only when an email matches your rules. Everything else stays quiet, so you can stop checking “just in case.” What you’ll see in the push alert • Rule label (e.g., “Boss”) • Sender • Subject line What push alerts do NOT include • Email body content • Attachments • Full inbox access inside the app Alert Details (in-app and on the web) When you open an alert, OWL can show up to 10,000 characters of context for that matched email—so you can decide quickly without opening your full inbox. Attachments are never included. Rule setup • Create and manage rules in the app or on the OWL website (vip.foundopportunity.com). Built for “can’t-check-right-now” moments Meetings, dinner, sleep, driving, and anything else where you want to stay present without missing the one email that matters. Important This is a companion app and requires an active OWL subscription. You must first sign up and connect your email account through the OWL website (vip.foundopportunity.com). Privacy & security Email processing happens server-side on the secure OWL platform. Push alerts contain only the rule label, sender, and subject. OWL does not include email bodies or attachments in push notifications.
