Built in the open.
Shipped in the open.

The biggest release since the rebuild. STAMP is no longer a Gmail client with ambitions: Outlook.com and Microsoft 365 now connect over Microsoft Graph, and every provider walks in through the same door.

New and improved

• Outlook.com and Microsoft 365 support. Sign in with your Microsoft account and your mail syncs over Graph, side by side with Gmail.
• One add-account flow. A single place to add any account, with a provider picker up front. No more guessing which button is yours.
• Identities. Your send-as addresses now live in Settings, and the composer's From picker knows every one of them.
• Thread merging. When headers show two threads were always one conversation, STAMP merges them and keeps following the merged thread instead of losing it.
• Crash reporting and a feedback dialog. Both scrubbed by default: reports carry no mail content, ever.
• Faster triage recompute. A scheduler replaced the old fan-out, so each thread is recomputed exactly once no matter how many messages arrive.

Fixes and polish

• Dropdowns close when you click anywhere else.
• The interface stops lying once there is more than one mailbox: counts and scopes now reflect every connected account.
• A thread followed through a merge no longer disappears from the list.

STAMP has said "paid from day one" since the first landing page. This release makes it true.

New and improved

• Payment gating. Plans activate through Stripe: Monthly $9, Yearly $79, Lifetime $199, all locked at founding rates for as long as you stay on them.
• Invite-only launch. The founding window is capped at 500 seats. Join the waitlist and your invite lands within about 7 days.
• The affiliate program. Refer someone and you get 2 free months of STAMP credit. Transparent terms, no PDF on page nine.

Under the hood

• Every mail provider now sits behind one seam in the codebase. Invisible today, but it is the groundwork that made the next release possible.

The release where STAMP grew from "reads your mail well" to "runs your mail well".

New and improved

• Send later. Write the reply at 11 p.m., have it land at 8 a.m. Pick a time, hit send, forget it.
• Settings. A real settings surface instead of scattered toggles.
• Attachment search. The one search field now looks inside attachments too, across every account.
• Folders and tags. File threads your way, and find them again without remembering which account they live in.
• A branded DMG installer. Downloading STAMP now looks like downloading STAMP.

Fixes and polish

• The release pipeline signs and notarises correctly on every run, so updates arrive without Gatekeeper drama.
• Windows and Linux builds are parked on purpose: one platform done properly beats three done badly.

Small release, sharp focus: writing mail should feel as fast as reading it.

New and improved

• Rich text in the composer. Bold, italics, lists and links, without leaving the keyboard.
• Recipient suggestions. The To field suggests people you have actually written to, ranked by how often.
• Standard mailboxes. Inbox, Drafts, Sent and Trash now live in the scope menu, one keystroke apart.

One day after the rebuild shipped, STAMP stopped being read-only.

New and improved

• Compose and send. Reply, forward, delete. The full loop, from any connected account.
• Multiple accounts. Connect a second Gmail account and both stream into the same window.
• Sync freshness. A quiet indicator tells you exactly how current each account is.
• Keyboard reference. Press ? and every shortcut is on screen. J and K to move, R to reply, E for done.
• Full-width reading pane. Long threads get the whole window, not a squeezed column.
• Mailbox labels on rows. Each row says which mailbox it landed in, so a unified list never gets ambiguous.

Fixes and polish

• Three reachable panics on remote input are gone, and a list that could not scroll now scrolls.
• Connecting a second account actually connects a second account.
• Cancelling a Google sign-in reads as a cancellation, not an error.
• The pending operation queue drains correctly, so offline actions land once you are back.

The first public build of STAMP, and also a complete rebuild. Months of SwiftUI prototyping taught us what the app should be. This release rebuilds it on foundations that can carry it.

New and improved

• Ported to Tauri 2, Svelte 5 and SQLite. A native shell, a fast interface, and every message indexed in a local database on your Mac.
• Gmail sync. Connect a Gmail account over OAuth and your inbox syncs down, classification and all, without a copy landing on our servers.

Why the rebuild

The SwiftUI prototype proved the triage idea worked. It also proved the architecture could not carry multiple providers, offline queues, or a real local index. Rather than patch around it, we rebuilt. Everything since this release stands on that decision.
