Inbox splits
Upstream splits the inbox into categories like Needs Reply and Follow Ups so important mail is surfaced separately from noise such as newsletters and other low-priority messages.
Upstream
Upstream is a messaging app for teams built on top of email. It combines inbox organization, AI reply drafting, follow-up assistance, and team collaboration features.
Overview
Upstream is a messaging app for teams built on top of email. It reorganizes the inbox into work-oriented splits, adds AI drafting and follow-up help, and gives teams ways to share, comment on, and manage conversations without relying on forwarding.
The product is positioned for both people and agents: the site describes it as an inbox for humans and agents, with separate pages for teams and for agents. Pricing ranges from a free Core plan to paid Pro and Max tiers with additional AI controls, collaboration features, and enterprise support options.
Core capabilities
AI reply drafting
The product drafts replies in the user’s voice and tone, using recipient context, thread history, and past messages to tailor suggestions to the conversation.
Follow-up assistance
Smart Follow Ups helps surface or prepare follow-up activity, with tiered limits shown on the pricing page and higher tiers unlocking unlimited usage.
Team collaboration
Team tools include shared channels, private channels, followers, team comments, and channel history so conversations can be discussed without forwarding threads around.
AI control and admin features
Advanced plans add configurable prompts, AI search, support for all OpenAI and Claude models, multiple accounts, and enterprise-oriented support and onboarding options.
Access and workflow fit
The pricing page also references mobile access and a Granola integration, while the site’s agent-focused pages present the product for human and agent workflows.
Where it fits
Shared team inboxes
For teams handling shared inboxes or customer-facing mail, Upstream helps route conversations, share context, and leave comments without forwarding threads back and forth.
Drafting replies with AI
For people who want help replying faster, the AI draft flow produces suggestions in the user’s voice so they can open a thread, adjust the draft, and send it.
Prioritizing daily email
For inboxes with a mix of urgent mail, newsletters, and long-running threads, the split inboxes separate follow-ups, starred items, and low-priority messages into distinct views.
Collaborative discussion around email
For teams that need tighter coordination around specific conversations, channels and followers let people observe or join a thread while keeping access manageable.
Enterprise-style deployment
For larger organizations, the Max plan is presented as the option for advanced security, AI needs, dedicated support, and onboarding.
