← LockerWhat's New
Every release, in plain English.
Locker 0.5.7
July 2026LatestA cleaner reply, and the basics.
Replies don't shout at you
- Replying no longer dumps the whole original email into the box as raw quoted text. You get a clean space to write, with the original tucked behind a “••• quoted text” toggle (still sent).
About + Help
- An About window with the version number, and a Help menu (support + keyboard shortcuts). ⌘N starts a new message.
Fixed
- Send big files straight from compose via an encrypted Locker Drop link. And the Send buttons no longer get cut off in a small window.
Locker 0.5.6
July 2026Compose, leveled up.
Undo Send
- Hit send, then get a few seconds to catch it — a quick Undo before the message actually leaves.
Send Later
- Schedule a message for in an hour, this evening, or tomorrow morning. It waits in Drafts and goes out on its own.
Choose who you send as
- A From picker — if you run multiple domains on one account, pick which address a message goes out as.
Fixed + polished
- Forwarding now keeps the original's attachments (it used to drop them). Start typing a recipient and Locker suggests people you've emailed.
Locker 0.5.5
July 2026Fixes a launch crash.
Fixed
- Fixed a crash on launch in 0.5.3–0.5.4 (the app couldn't find its updater component). If Locker wouldn't open, this version fixes it.
Locker 0.5.4
July 2026A quick one.
Maintenance
- A small under-the-hood update — and the first one that installs itself with a single click if you're on 0.5.3. Your mailboxes, license, and settings are untouched.
Locker 0.5.3
July 2026Updates that just… update.
One-click updates
- This is the last time you'll download a disk image and drag Locker to Applications. From here on, a new version downloads in the background and installs with a single “Install and Relaunch” — no dragging, no disk images. Your mailboxes, license, and settings stay exactly as they are.
Locker 0.5.2
July 2026Sending a big file? Skip the bounce.
Big-attachment helper
- Attach a file too big for most inboxes and Locker offers a one-click way to send it as an encrypted, self-destructing Locker Drop link instead — no size limit, decrypted right in the recipient's browser. It only shows up when it's actually useful.
Locker 0.5.1
July 2026Multiple domains on one account, and a cleaner connect.
Send from any of your addresses
- Run several domains off one mailbox (like Fastmail)? Add your other addresses under an account, and Locker replies from whichever one the message was sent to — so a note to hello@yourbrand.com is answered from hello@yourbrand.com, not your main login. It even suggests the addresses it already sees in your mail.
Fixed
- Connecting a mailbox that hiccups on the first try no longer leaves a phantom duplicate account (and any existing duplicates are cleaned up automatically). A mailbox that's already connected won't be added twice.
Locker 0.5.0
July 2026Try it free for 14 days — no card.
Free 14-day trial
- New here? Open Locker, enter your email, and the whole app is yours for 14 days — no credit card. You'll see the days left right in the app, and can upgrade to keep it forever whenever you're ready.
Clearer pricing
- The current offer — including any active discount — now shows inside Locker exactly as it does on the site, so you always see the real price before you buy.
Smoother setup
- Picking a provider (Gmail, iCloud, Fastmail, Yahoo) now clearly highlights your choice and fills in the right hints.
Locker 0.4.0
July 2026A real daily driver — steadier sync, notifications that respect you, and your own rules.
Rock-solid sync
- Fixed the bug that could leave a Gmail account stuck after a hiccup — Locker now retries and recovers accounts automatically instead of going quiet.
Attachments
- View, download, and send attachments on your Gmail accounts.
Work accounts (beta)
- Connect a work / Outlook / Microsoft 365 account that blocks IMAP by adding it through Apple Mail, locally on your Mac — no OAuth app, no admin approval. A very large corporate inbox can be slow to fill in (Apple Mail downloads the whole mailbox); best today for Gmail and smaller work mailboxes.
Reply the way you actually do
- Reply, Reply all, and Forward. Cc and Bcc. Replies thread properly in the other person's inbox.
- One-click copy of any address in an email — even ones buried in a forwarded chain.
Smart notifications
- Native banners only for what matters: an urgent message, a security alert, or your morning Brief. Set VIPs that always reach you, mute the noisy ones, pick quiet hours.
Rules + reminders
- Build your own rules — “when my biggest client emails about invoices → notify me.” Tag any email. Snooze with remind-me and get a banner back at 3pm or tomorrow.
Polish
- Per-account inbox view. “Search by meaning” now drives the command bar (and never archives by mistake). Faster and more native — now using Apple's own system fonts.
Locker 0.3.0
June 2026Search that understands what you mean.
New
- Search your inbox by meaning, not just keywords. Type “baby stuff” and Locker surfaces the Carter's order, the stroller sale, the daycare email — even when none contain the word “baby.” It runs entirely on your Mac.
- Locker picks its own network ports on launch, so it never collides with other apps.
Locker 0.2.0
June 2026New
- Automatic updates — Locker tells you when a new version is out and updates with a click; your mailboxes, license, and settings stay exactly as they are.
- A real command bar at the top of every screen — type plain English and Locker does it.
- Sent box — every reply you've approved, with a link back to the original.
Improved & fixed
- Paste (⌘V) works everywhere. Removing a mailbox is a clear button. The on-device AI stays warm instead of reloading per email. The top search bar is wired up. Marketing mail no longer shows under “needs you.”
Locker 0.1.0
June 2026First build
- Locker for Mac — a private AI inbox that runs on your own Mac. Sorted, answered, and protected by the Mac's on-device AI; nothing leaves your device. Signed & notarized by Apple.
