Why Velo?
Most email clients are slow, bloated, or send your data to someone else's server. Velo is different:
- Local-first -- Your emails live in a local SQLite database. No middleman servers. Read your mail offline.
- Keyboard-driven -- Superhuman-inspired shortcuts let you fly through your inbox without touching the mouse.
- AI-enhanced -- Summarize threads, generate replies, and search your inbox in natural language -- with your choice of AI provider.
- Native performance -- Rust backend via Tauri v2. Small binary, low memory, instant startup.
- Private by default -- Remote images blocked, HTML sanitized, emails rendered in sandboxed iframes. Your data stays on your machine.
Features
- Multi-account support: Gmail (API) and IMAP/SMTP (Outlook, Yahoo, iCloud, Fastmail, and more) with instant switching
- Threaded conversations with collapsible messages
- Full-text search with Gmail-style operators (
from:,to:,subject:,has:attachment,label:, etc.) - Command palette (
/orCtrl+K) for quick actions - Drag-and-drop labels, multi-select, pin threads, mute threads, context menus
- Split inbox with category tabs (Primary, Updates, Promotions, Social, Newsletters)
- Inline reply, contact sidebar with Gravatar
Composer
- TipTap v3 rich text editor (bold, italic, lists, code, links, images)
- Undo send, schedule send, auto-save drafts
- Multiple signatures, reusable templates with variables
- Send-as email aliases with from-address selector
- Drag-and-drop attachments with inline preview
- Frequency-ranked contact autocomplete
Smart Inbox
- Snooze threads with presets or custom date/time
- Filters to auto-label, archive, trash, star, or mark read
- AI + rule-based auto-categorization (Primary, Updates, Promotions, Social, Newsletters)
- One-click unsubscribe (RFC 8058) and subscription manager
- Newsletter bundling with delivery schedules
- Smart folders / saved searches with dynamic query tokens
- Quick steps -- custom action chains for batch thread processing
- Follow-up reminders when you haven't received a reply

Installation
Download the latest release for your platform:
Download Velo -- Windows .msi / .exe • macOS .dmg • Linux .deb / .AppImage
No build tools or programming knowledge required -- just download, install, and run.
Account setup
Gmail: Create OAuth credentials in Google Cloud Console (enable Gmail API + Calendar API), then enter your Client ID in Velo's Settings. No client secret needed (PKCE).
IMAP/SMTP: Click "Add IMAP Account" in the account switcher. Enter your email and password -- Velo auto-discovers server settings for popular providers (Outlook, Yahoo, iCloud, Fastmail, etc.). For other providers, enter IMAP/SMTP server details manually. No Google Cloud project needed.
AI (optional): Add an API key for Anthropic, OpenAI, or Google Gemini in Settings. Then select which model to use for each provider.
