Changelog · Mailroom

0.6.0 October 4, 2026

Automatic updates. Mailroom checks for new versions, downloads them in the background, and installs them when you quit, or straight away when you click Restart. Mailroom › Check for Updates… checks now.
Move to Applications. If Mailroom is running from somewhere it can’t update itself, such as your Downloads folder, Settings › About offers to move it into Applications.

Signed and notarized by Apple. Mailroom opens like any other Mac app, and macOS stops asking about the Keychain after each update.
A new icon, in amber.
Fixed: if a window couldn’t load its settings when it opened, Mailroom held off marking messages as read. It now tries again.

Appearance settings. Choose light, dark or the same as macOS, an accent colour, the text size, how compact the message list is, and whether Calendar and Contacts appear in the sidebar.
Terms of Use and Privacy Policy. Mailroom asks you to agree to them the first time it opens, and links to them from the Help menu and Settings › About.
Fixed: AI replies, translations and summaries could come back empty with models that think before they answer.

Add any account. Pick Gmail, Outlook.com, Microsoft 365, Yahoo, iCloud, Fastmail, Purelymail, Proton Mail Bridge, Zoho, AOL, GMX, Yandex, Mail.ru or any other IMAP server. Mailroom fills in the server settings and tells you which password to use.
Settings found for you. Type your address and Mailroom works out the rest, even for your own domain. Only the domain is looked up, never your address.
Sign in with Google, Microsoft or Yahoo in your browser, through an app you register with them. Outlook.com and Microsoft 365 need this.
Signatures on replies are optional. Turn them off for replies and forwards, and add one to a single message when you want it.
New settings: how long Undo Send waits, when mail is marked as read, notifications for all mail or only your contacts, images loaded automatically in mail from your contacts, and AI that runs on your Mac with Ollama or LM Studio.
About in Settings, with version details, Open at Login and a shortcut to your data folder.

Print a conversation or a single message, or save it as a PDF.
Translate. Mailroom notices mail in another language, on your Mac without sending anything, and offers to translate it.
Summarize a long conversation in a few sentences: what’s been decided and what’s still open.
Invite people to your events. Guests get an invitation that Gmail, Outlook and Apple Calendar understand, and their answers show on the event. Changes and cancellations go out to them too.
Contacts, synced with your provider’s address books or kept on your Mac. People you’ve emailed are a click away from being added, and your contacts come first when you type a recipient.
Safer reading: an Unsubscribe link on newsletters, a check before opening a link that may not go where it says, a warning when your mail server couldn’t confirm who sent a message, and Show Original.

Message details. See who a message was from and to, cc and bcc, which server sent and signed it, and whether it arrived over an encrypted connection.
A menu on every message in a conversation, and on right-click: Reply, Reply All, Forward, Delete, Report Spam, Mark Unread from Here, Move To, Star and Save As.
Zoom with ⌘+ and ⌘−. Mailroom remembers the size.
Better AI replies. Reply with AI reads the whole message you’re answering, and the gist of the messages before it.

Fixed: calendar sync with Purelymail. New events no longer vanish for a moment after you save them, and editing an event no longer makes a copy.
Fixed: blocked images leave empty space instead of broken-image icons.

The first version, for Apple silicon and Intel Macs.

Mail from any IMAP account: conversations, search, tags, new mail as it arrives, undo, working offline, drafts and Undo Send.
Keyboard shortcuts from Gmail and the Mac.
A calendar that syncs over CalDAV, with invitations you can answer from your inbox.
Reply with AI.
