Mailroom is a desktop email client that keeps your mail on your own computer.
It works with Gmail and Google Workspace, and with Microsoft 365 and Outlook. Your mail, calendar and contacts are stored in an encrypted database on your own machine, and the app is fully usable with no network.
There is no Mailroom server. There is no account to create with us, and no sign-in of ours — you sign in to Google or Microsoft. Nobody at Sorted Solution can read your mail, because we never receive it.
Download
Mailroom is built for macOS and Windows. The macOS build is signed with a Developer ID certificate and notarized by Apple.
The builds are not published yet, so there is nothing to download from this page today.

What this release does
This first release is a mail client: mail, calendar and contacts. It does not classify or sort your mail for you.
It speaks the Gmail API and Microsoft Graph. It does not speak generic IMAP, so it will not connect to a mailbox that only offers that.
Where your mail lives
On your computer, in an encrypted database
- Your mailbox at Google or Microsoft Stays the system of record. Mailroom keeps a local copy of it and writes very little back.
- Mailroom, on your computer An encrypted SQLite database (SQLCipher) holding your mail, calendar and contacts.
- No Mailroom server Sorted Solution LLC hosts nothing and receives nothing. There is nowhere else for your mail to be.
The database file is at ~/Library/Application Support/Mailroom/mailroom.db on macOS, and %APPDATA%\Mailroom\mailroom.db on Windows.
Your OAuth tokens and the database key live in the operating system keychain — never in the database, never in a configuration file, never in a log line.
Google access
What Mailroom asks Google for, and why
Mailroom reads your Gmail messages and attachments so that it can show them to you, search them offline, and let you reply. It asks Google for exactly these permissions:
openid,email,userinfo.email- Identify which account signed in.
gmail.modify- Read mail and attachments; apply and remove labels; create and update drafts; send.
calendar- Read and write your calendar events.
contacts- Read and write your contacts.
drive.appdata- A private, app-only folder in your own Google Drive.
gmail.modify is a restricted scope in Google's classification. Nothing narrower does the job: gmail.metadata cannot read a body, gmail.labels cannot read mail at all, and gmail.send covers only sending.
Mailroom does not request gmail.compose or gmail.insert. Both were removed: gmail.compose was redundant, and gmail.insert writes messages into a mailbox, which the product forbids outright.
The Drive app-data folder
That folder holds the relationship record: the notes, projects, tags, links and pins you make about your contacts. It is invisible in Drive's own file browser, only Mailroom can read it, and it lives in your Drive rather than ours so that it survives a rebuilt database and follows you between machines.
Microsoft
For Microsoft 365, Mailroom asks for offline_access, openid, profile, email, Mail.ReadWrite, Mail.Send, MailboxSettings.Read, Calendars.ReadWrite, contacts, and Files.ReadWrite.AppFolder — the same app-only folder idea, in OneDrive.
What Mailroom writes back to your mailbox
Only labels and categories, drafts, and the messages you send.
It never deletes a message, never moves one, and never changes a flag you did not initiate.
Who else receives your data
Nobody. In this release no message content leaves your computer.
One optional feature is worth stating precisely. You may paste your own Anthropic API key to describe a filing rule in a sentence and have it turned into a rule. When you do, what is sent is the sentence you typed plus a list of field and command names — never a message, never a subject, never an address. With no key configured the feature is simply unavailable, and nothing is sent.
What never happens
- No advertising, and no advertising profile.
- No sale or sharing of personal data, and no transfer to data brokers.
- No human at Sorted Solution reads anyone's mail — we never receive it.
- No training of any model on anyone's mail.
- The app sends no analytics or telemetry anywhere. It has a Developer surface that shows you what it is doing; it is local and goes nowhere. This website measures its visitors with cookieless analytics — see the privacy policy.
Getting your data out, or removing it
- Revoke Mailroom's access at myaccount.google.com/permissions, or the Microsoft equivalent. The app stops being able to reach your mailbox immediately.
- Delete the local database at the path above. Nothing of yours remains anywhere else, because there is nowhere else.
Your mail is untouched by either. It is still in Gmail or Outlook, where it always was.
