Because your inbox became a second job you never applied for.
We built InboxSentry because we were living the same problem our clients were. Our team was spending the first hour of every day just triaging — not working, not deciding, not creating. Just sorting through noise to find the few things that actually mattered.
The tools that existed either required handing your inbox over to a cloud service, locked you into a monthly subscription, or only solved one narrow piece of the problem. None of them treated your email data with the same seriousness we apply to enterprise security.
So we built the tool we wanted: local-first, privacy-preserving, and capable enough to actually solve the whole problem — not just patch one part of it. One purchase. Your data stays on your machine. Your inbox finally works for you.
The inbox problems every professional knows
The inbox problem by the numbers
Six capabilities. One desktop app.
Complete inbox control.
Every dimension of the inbox problem — handled in one place.
Inbox Intelligence Scan
Maps every sender across your entire inbox — volume, category, and noise score — in seconds. Full situational awareness before you touch a single email.
Bulk Unsubscribe Engine
Remove yourself from dozens of mailing lists in a single pass using official unsubscribe headers and GDPR opt-out protocols. Not just deleted — stopped permanently at the source.
Intelligent Auto-Filing
Configure a rule once. Clients, invoices, receipts, project threads — routed automatically on arrival. Your inbox stops being a dumping ground and starts being an action list.
AI-Drafted Replies
InboxSentry reads the full thread and composes a response in your tone. Review, adjust if needed, and send. Replies that took 15 minutes now take under 60 seconds.
Sender Reputation Dashboard
Every sender gets a detailed profile — frequency, open history, category, and opt-out status. Data-driven decisions, not gut-feel guesswork.
Local-First Privacy
Runs entirely on your device. Your email content is never transmitted to external servers. Gmail and Outlook connected via OAuth 2.0 — your password is never exposed.
Installed and running in under ten minutes
Download the App
Native installer for Windows and macOS. No browser extensions, no cloud account. Up and running in minutes.
Connect Your Inboxes
Authorize Gmail, Outlook, or both through OAuth 2.0. Your credentials stay on your machine. Setup takes under two minutes.
Run Your First Scan
InboxSentry audits your full inbox — every sender, every category, every source of noise. Most people are genuinely surprised by what it surfaces.
Take Back Your Time
Bulk unsubscribe, activate auto-filing, and let AI draft your replies. What used to consume your mornings gets handled in 20 minutes.
What our customers actually experience
“I cleared 340 mailing lists in a single afternoon. My unread count dropped from 2,400 to 47. I had no idea how much mental overhead that was carrying until it was gone.”
InboxSentry vs. subscription-based tools
Most email management tools are cloud-based SaaS with monthly billing and server-side access to your data. InboxSentry processes everything locally and charges once.
Simple annual pricing. No surprises.
One annual fee covers your license, all updates, and support. Cancel anytime — no long-term contracts.
