A familiar inbox,
made smarter
Sorto is a private, intelligent email app for iPhone and iPad. Connect Gmail, iCloud Mail, or another IMAP account to read, organize, search, compose, and reply—all while Sorto identifies messages that need attention, summarizes conversations, and helps you focus on what matters.
Classification and supported AI assistance run on your device. Your credentials remain protected in the device keychain, and Sorto never sends a message without your approval.

A familiar inbox, made smarter
Sorto works like the email app you already understand, with search, unread state, multiple accounts, Sent mail, local Archive, composing, replying, and bulk actions. Its intelligence stays visible but unobtrusive.
Highlights
- Unified inbox with per-account mailboxes
- Search, selection, read and unread state, local Archive, and compose
- Concise Sorto Brief above the original email
- Smart categories that explain why a message matters
Focus on what needs attention
Focus creates a short, guided session from messages that may need your attention. Review Sorto’s brief, reply, snooze, correct the classification, archive, mark the message done, or skip it. Sorto learns from your corrections without hiding the original email.
Highlights
- Guided sessions built from messages that may need attention
- Reply, snooze, archive, mark done, correct, or skip
- Original email always remains available
- Supported reply assistance runs on-device
Signals you can understand
Sorto groups messages into clear, user-facing views such as Needs Attention, Updates, Opportunities, People, Snoozed, and Noise. Category icons and short explanations help you see why a message surfaced without turning your inbox into a dashboard.
Highlights
- Needs Attention for messages that may require action
- Updates and Opportunities kept easy to find
- People, Snoozed, and Noise remain clearly separated
- Correct a classification to improve future results
Privacy is the architecture
Classification and supported AI assistance happen on your device. Email content is not sent to 3Nsofts servers or third-party AI providers. Credentials remain protected in the device keychain, and Sorto never sends a message without your approval.
Highlights
- Classification and supported AI assistance run on-device
- Email content is not sent to 3Nsofts servers or third-party AI providers
- Account credentials are stored in the device keychain

Questions
Frequently asked questions
Does Sorto send my emails to a server?
Sorto connects directly to your configured mail provider to receive and send mail. Classification and supported AI assistance run on your device; email content is not sent to 3Nsofts servers or third-party AI providers.
Which email providers are supported?
Sorto supports Gmail with a Google App Password, iCloud Mail with an Apple app-specific password, and other compatible accounts that provide secure IMAP access for receiving mail and SMTP access for sending. Availability depends on each provider’s server and app-password requirements.
What does Sorto Archive do?
Sorto maintains its own local Archive. Archiving a message in Sorto does not move that message on your email provider’s server. Sorto does not permanently delete messages or silently send replies.
Will Sorto notify me immediately when an important email arrives?
Sorto can notify you about important unread messages after it refreshes your mailbox. iOS schedules background refresh based on system conditions, so delivery is not guaranteed to be immediate. Opening or manually refreshing Sorto always checks for new mail.
Does Sorto work on Mac?
No. Sorto 2.1 supports iPhone and iPad and requires iOS 26 or iPadOS 26. Mac Catalyst is not enabled.
What is Focus?
Focus creates a guided session from messages that may need attention. You can review the brief, reply, snooze, correct the classification, archive, mark the message done, or skip it while keeping the original email available.
Does Sorto send email automatically?
No. Sorto never sends a message without your explicit approval.
How Sorto was built
Technical notes behind the app.
The product pages show what shipped. These guides and case studies document the architecture patterns, privacy decisions, and SwiftUI implementation details behind apps like Sorto.
You remain in control
Read for Classification
Sorto reads messages over a secure connection to classify and prioritize them on-device.
Send Only With Approval
Sorto sends a reply only when you explicitly approve it. It never sends email automatically.
Local Sorto Archive
Sorto can mark messages read or unread and maintain its own local Archive. Archiving does not move the message on your email provider’s server.
Sorto does not permanently delete messages or silently send replies. Some mailbox actions remain local to Sorto rather than changing the message on your provider’s server.
