New mail, the moment it lands
Snappy Mail keeps a live connection to your inbox, so new messages — and a notification — appear as they arrive. After sleep or a dropped connection it catches up straight away, and never alerts you twice.
Version 0.1.0 · now on Mac, Windows & Linux
Your email,
Your email,
beautifully fast.
Snappy Mail is a modern desktop email app for any IMAP account — Gmail, iCloud, Fastmail or your own domain. A clean, familiar layout, new mail the moment it arrives, and your messages never pass through anyone else's servers.
Works with Gmail · iCloud · Fastmail · Yahoo · your own domain — any IMAP & SMTP account
Everything you need, nothing you don't
Thunderbird-level power.
A refreshingly calm design.
All the mail handling you'd expect from a serious desktop client, in an interface that feels light, quick and familiar from day one.
One inbox for every account
Work, personal, side project — read them all together in a unified inbox, with Flagged, Drafts and Sent combined too.
Set up in seconds
Type your email address and Snappy Mail finds the right server settings for you — from your provider, the Thunderbird database or your domain's mail records.
Signatures that look the part
Design an HTML signature with your logo, links and colours — or paste one straight from Outlook, Gmail or a signature generator.
Light, dark and your colour
Follows your system theme, with seven accent colours, three densities, cards or a classic table, and the reading pane where you want it.
Conversations & search
Replies grouped into threads, instant results as you type, then a full search of your mail server across every folder.
Undo send & autosaved drafts
Five seconds to change your mind after pressing Send. Drafts save to your mail server as you type, so they're on every device.
Organised your way
Pin, flag, tag, archive and move — between folders or accounts — with keyboard shortcuts for the things you do most. Changes sync back to your server.
Conversations
Every reply in one calm view
Snappy Mail threads messages the way you read them, with the latest reply open and earlier ones a click away. Pin what matters, flag what needs doing and tag anything with Thunderbird-compatible tags.
- Threads by Message-ID, so replies never get lost
- Meeting invites, attachments and one-click unsubscribe
- Undo for delete, archive and move
Compose
Write with confidence
Rich formatting, attachments up to 25 MB and your HTML signature already in place. Replies pick the right account automatically, and you get five seconds to undo a send.
- Per-account HTML signatures with logos
- Address suggestions from people you've written to
- Pasted images are sent as proper inline images
Setup
From download to inbox in a minute
Enter your name, email address and password. Snappy Mail looks up your provider's settings, tests the connection and loads your folders — no hunting for server names.
- Provider autoconfig, Thunderbird ISP database and MX lookup
- Clear, human error messages if something's wrong
- Tips for app passwords on Gmail, iCloud and Yahoo
Make it yours
Your layout, your colours
Reading pane on the right, at the bottom or hidden. Spacious cards or a dense classic table. Light, dark or system, with an accent colour to match your style.
- Seven accent colours and three densities
- Resizable panes that remember their size
- Native title bar integration on Mac and Windows
Privacy first
Your mail stays between you and your provider
There's no Snappy Mail account and no cloud service in the middle. The app runs on your computer and connects directly to your own mail servers.
No middleman
Messages travel straight between your computer and your mail provider, over secure SSL/TLS connections wherever your provider offers them.
Trackers blocked
Remote images — the usual way emails track you — stay blocked until you choose to show them for a message or a sender.
Sandboxed content
Emails are displayed in a locked-down sandbox where scripts and forms can't run, and risky attachments are always saved, never opened.
Encrypted passwords
Your account passwords are stored encrypted on your own computer, readable only by your user account.
Locked to the app
Snappy Mail's mail engine only answers its own window — other programs and other users on the computer can't use it.
No tracking in the app
No analytics, no telemetry and no ads. Snappy Mail doesn't report anything about you or your mail to anyone.

Questions
Good to know
Which email accounts work with Snappy Mail?
Any account that offers IMAP and SMTP, which is almost all of them: Gmail, iCloud, Fastmail, Yahoo, AOL, Zoho, most internet providers and hosting companies, and your own mail server. Gmail, iCloud, Yahoo and Fastmail ask you to create an app password to use instead of your normal one; Snappy Mail shows you where when you add the account.
Does it work with Outlook.com or Microsoft 365?
Not yet. Microsoft only allows browser sign-in (OAuth) for those mailboxes, which is coming in a future version.
Where is my email stored?
Your mail stays on your mail provider's servers, exactly where it is today, so it stays in sync with your phone and webmail. Snappy Mail keeps only your account settings on your computer, with passwords encrypted.
Why does my computer warn me when I first open it?
Mac and Windows show a one-time check for apps that aren't code-signed yet, which is normal for early releases. The steps above get you past it. You can also check your download against the SHA-256 checksums listed above.
Does it support POP3?
IMAP is supported today. POP3, which downloads mail to your computer, is coming soon.
How do I update?
Download the latest version from this page and install it over the old one. Your accounts and settings are kept.
