Email, drafted in your voice. Inbox, triaged by AI.
River Mail brings your inbox into the same workspace as your docs, decks, and projects. The AI knows what you've sent before, who you're talking to, and what matters today.
Free to start · No credit card required
Mail apps don't know who your customers are. Workspaces don't get your email. River Mail is both — a real inbox that lives next to your Spaces, with an AI that drafts replies in your voice and routes messages into the right project.
AI triage and inbox tiers
Important, useful, noise — sorted automatically and explained in plain language so you trust the call.
Voice-preserving draft replies
River learns how you write to each contact and drafts in that voice. No more generic ChatGPT replies.
Route into Spaces
Email about a deal lands in the deal's Space. Conversations stay with their project context.
Smart folders
Define folders in plain language (“investor updates”, “vendor approvals”). River sorts continuously.
Connected to your AI
Reference an email from a doc, summarise a thread, generate a follow-up — the AI has the full context.
