Every email signal across 12 mail apps, in one feed. From $18/mo. Email Activity TrackingSome of the worst things happening on your kid's phone start with an email. Some of the worst things happening at your company involve email leaks. TheOneSpy captures email activity across Gmail, Outlook, Yahoo, ProtonMail and nine other apps on managed Android and iPhone devices. Sender, subject, recipient, attachments. The signals that tell you whether to worry. Without crossing into reading personal correspondence.
Use it legally. TheOneSpy is for devices you own, or company-issued equipment where employees have been given proper notice. Check your local laws first. See our Terms, Privacy, Disclaimers, and Abuse Policy.
Specific capabilities — not category promises. Here's what's on your dashboard after setup.
Gmail, Outlook, Yahoo Mail, ProtonMail, Apple Mail, AOL, Zoho, FastMail, GMX, Tutanota, iCloud Mail, Outlook for Business. If it's on the device, we log it.
Who emailed whom and when. Frequency views surface recurring contacts. New addresses get flagged automatically as 'first contact this device has seen'.
Filename, size, MIME type. Not the contents. Enough signal to spot a confidential.pdf leaving via personal Gmail to a competitor's domain.
Build rules: 'flag emails to non-corporate domains', 'alert on subject lines matching X', 'notify if .doc attachment goes to external recipient'. Real-time push to your phone.
Track three Gmail accounts and an Outlook on one device? Each shows up separately in the dashboard. No mixing. Cleanly labeled by account.
Find every email from a specific address, every attachment over 5MB, every email between 11pm-2am. Filter, search, export to PDF or CSV in two clicks.
It takes about five minutes the first time. After that, you control the device from your browser — forever.
If it's your own phone or your child's, you're set. For company-issued devices, make sure the employee has signed the standard monitoring notice. Two-minute check, then you're clear.
Grab the device for five minutes. Install TheOneSpy, sign in to your account, and grant the permissions it asks for. That's it — you won't need physical access again.
Open your TheOneSpy dashboard in any browser. The feature shows up under your devices and works without you touching the phone or computer again.
A few moments where this specific feature earns its place in the dashboard.
Strangers reach kids via email more often than parents realize. Gaming forums, fan sites, content creators with fake personas. The first warning sign is an email pattern that doesn't match anyone the kid actually knows.
Employee on a 30-day notice period starts forwarding spec files to their gmail.com address. Attachment metadata catches it on day three. Not day 28. Not after the docs are already at a competitor.
Fake college admission portals. Scholarship scams. Romance scams targeting first-year students living away from home. Pattern alerts flag suspicious senders before your kid clicks the wrong link.
Coverage varies by operating system. Full parity isn't always possible — each OS handles third-party access differently.
If something else is on your mind, hit Contact Support — we usually reply within a few hours.
No, by design. We capture metadata. Reading personal correspondence is intrusive, raises legal risk in most jurisdictions, and isn't necessary for the oversight families and businesses actually need.
Yes. Activity logging works at the app level. We see what the user sees in their own inbox. ProtonMail's encryption protects messages in transit; it doesn't block app-level visibility on the device itself.
Webmail (gmail.com in Chrome, outlook.live.com in Edge) shows up in browser history. Granular email-app logging covers the native apps. Both data streams flow into the dashboard.
Yes. Activity is logged as it happens, in real-time. Even if the user deletes an email five seconds after reading it, the log entry persists in your dashboard for the duration of your retention setting.
Yes. SSO doesn't change the underlying email app. We observe what's on the device after the user signs in, regardless of whether they authenticated via Okta, Azure AD, or username/password.
Inbox events sync within 90 seconds on Android. iPhone takes 3-5 minutes due to iOS background processing limits. Sent activity is near-instant on both platforms.
90 days for free-plan accounts. Pro plans: 6 months. Enterprise: 24 months by default, configurable up to 7 years for regulated industries.
TheOneSpy appears in the device's installed apps. We don't support hiding it. Deploy transparently: kids should know parents check, employees should sign the policy.
Plans from $18/mo. 14-day refund. 12 email apps supported.
