LetterRay is an email app for Gmail, iCloud, Outlook, Yahoo and your work mail. Add your mailboxes once and they show up on your iPhone, Android, Mac, Windows and in the browser.
No ads · iPhone, iPad, Android, macOS, Windows, Linux and web
Personal, work, that old address for newsletters — mail from all of them lands in one inbox. A colour dot shows which inbox it came to, and your reply goes out from the right address.
Enter your address and password and LetterRay finds the server settings. Mailboxes, folders and your signature live in your account, so on a new phone or computer you just sign in.
A dense, calm list, large message text and the gestures you already know from your phone's own mail app.
You're notified the moment a message arrives, even when the app is closed. Mute a newsletter or a noisy sender with one swipe: their mail keeps arriving, silently, on every device at once.

Sender muted — it's in your inbox, your phone stays quiet.
LetterRay follows your system theme. Designed emails stay readable: their layout doesn't break or turn into a mess.
Sender, subject, message text — search everywhere at once, not one mailbox at a time.
Start on your phone, finish on your computer. Drafts are saved to your mailbox.
PDFs and images open right in the app.
Folders, flags and read state match what you see in any other mail app.
One account, every device. A free plan and a Pro subscription.
iOS and iPadOS 15 or later
Version 1.0.0, released 28 September 2026. A Google Play version is coming; for now the Android app installs from an APK.
Pro features are free during early access. After subscriptions launch, Free will include one mailbox and Pro up to ten mailboxes for RUB 249 per month. Subscribe on the website with your LetterRay account; Pro works on every device. Your early-access status and available payment options are shown in Subscription settings.
Anything with IMAP: Gmail, iCloud, Outlook, Yahoo, Fastmail, Yandex and work mail on your own domain. LetterRay finds the server settings from your address; if it can't, you can enter them by hand.
No. Mailboxes belong to your LetterRay account: sign in on a new device and your mailboxes, folders and signature are already there.
Gmail, iCloud and Yahoo don't let mail apps sign in with your normal password. Create an “app password” in your email account's security settings and paste it into LetterRay instead. The app tells you when you need one.
LetterRay connects to mail servers over encrypted connections only, and mailbox passwords are stored encrypted. You can delete your account at any time in Settings: data on our server is removed immediately, and your mail at your provider stays untouched.
See the privacy policy for details.
Download the APK and open it. If Android asks, allow installs from that source. A Google Play version is coming.
The Windows installer isn't code-signed yet, so SmartScreen shows a warning. Click “More info”, then “Run anyway”.
