Nubo Email

Nubo Email is a fast, private email client for your own mail server. Connect to any JMAP-compatible server (such as
Stalwart) and keep your mail, calendar, and contacts in one secure app — no third-party servers in the middle, no ad
tracking, no mining your inbox.

Built for people who run their own email or use a privacy-first provider, Nubo Email puts you in control of your data.

WHAT YOU CAN DO
• Sign in to any JMAP mail server in seconds — scan a QR code from webmail or enter your server details
• Manage multiple accounts side by side and switch between them instantly
• Read, search, and organize email with fast threaded conversations
• Compose, reply, forward, and attach files, photos, or documents
• View your calendar and events alongside your mail
• Browse your contacts and address book
• Get real-time push notifications for new mail
• Receive in-app updates as new versions ship

PRIVATE BY DESIGN
• Direct connection to your own server — your messages are not routed through us
• No advertising, no tracking, no inbox scanning
• Credentials stored securely on your device
• Open source under the AGPL-3.0 license

WHO IT'S FOR
Nubo Email is ideal if you self-host your email, use a JMAP-based provider, or simply want a clean, modern mail app
that respects your privacy.

BETA NOTICE
Nubo Email is under active development. Some features — including filters and rules, S/MIME, themes, and file storage
— are still in progress, and you may encounter bugs. We don't yet recommend it as your only email app. Your feedback
helps us improve.

Requires a JMAP-compatible mail server. Nubo Email is a client app and does not provide email hosting.
