Sorto — email intelligence app hero screen

Sorto is an AI-powered email productivity app that works with Gmail, iCloud Mail, Outlook, and any major IMAP/POP provider. It helps users review, prioritize, classify, and reply to email faster using on-device Apple Intelligence.

Sorto connects using a secure app-specific password and standard email protocols, with account credentials stored only in the device keychain. Email messages are read on your device to classify and prioritize your inbox, and replies can be sent only when explicitly approved by the user.

Requires iOS 16+ · iPhone, iPad & Mac

The Problem

Your inbox is running you

You're managing client relationships, tracking opportunities, and running your business — all while drowning in newsletters, GitHub notifications, and automated alerts.

Important client messages get buried. Opportunities slip through. Your inbox controls you instead of helping you. Most email AI apps fix this by sending your emails to a cloud server — your most sensitive business conversations processed on someone else's machine.

Inbox overload should not bury the conversations that actually move your day forward.

Eight categories. Zero guesswork.

The moment your email arrives, Sorto reads it and decides what matters — not with a server somewhere in a data centre, but on your device, in seconds. Every message is classified into one of eight smart categories.

Highlights

  • Needs Our Reply: emails waiting on you
  • Opportunity: investor intros, partnerships, new business
  • Active Client: ongoing conversations that matter
  • Waiting on Reply: threads you've sent and are tracking
Sorto inbox categories — eight smart classifications
Sorto Command Center — inbox prioritised by what matters now

  • Opportunities and active clients grouped for instant access

  • AI-assisted reply drafting powered by Apple Intelligence

Questions

Frequently asked questions

Does Sorto send my emails to a server?

No. Email processing and classification happen entirely on your device. Email content is not transmitted to 3Nsofts servers or third-party AI providers.

Why does Sorto need access to my email account?

Sorto needs permission to read email messages so it can classify conversations, prioritize important messages, and generate reply suggestions. Gmail and iCloud Mail connect using an app-specific password; other providers use standard IMAP or POP where supported. Replies are sent only when the user explicitly approves them.

Can Sorto delete or modify my emails?

No. Sorto does not delete, archive, move, label, or permanently modify email messages.

Which email providers are supported?

Sorto supports Gmail via app-specific password, iCloud Mail via app-specific password, Outlook, and other major IMAP or POP providers where the provider supports standard email access.

Does it work on iPad and Mac too?

Yes. Sorto is built for iPhone, iPad, and Mac. On iPad and Mac you get a full sidebar with live category counts so you can navigate your entire inbox at a glance.

What is Focus Mode?

Focus Mode surfaces every email waiting on your reply, one at a time. You can draft an AI-assisted reply, snooze to tomorrow, or mark it done — clearing your queue systematically without distraction.

How accurate is the classification?

Sorto uses Apple's on-device Foundation Model to read each message and sort it into purpose-built categories so the important conversations surface first.
