Upstream - The inbox designed for humans and agents
by•
Finally, an inbox you'll look forward to. Agents sort your messages, draft your replies, and clear the grunt work behind the scenes, all in a client so well-crafted that email feels light, fast, fun.

Great product! I tested it and I'm pleasantly surprised by its effectiveness! It manages my emails very well, with highly relevant suggested replies that save me time—just reread and send! I haven't tested the collaborative aspect with my team yet, but the promise is there: working together on emails to provide the best possible responses, all while staying aligned with everyone, and all powered by AI. I highly recommend it!

This looks great, but I'm just concerned about privacy... especially when dealing with internal emails containing confidential information. I have safeguards matching the sensitivity of the information, but having an AI agent reading and classifying my emails may be a risk factor. Anything you can suggest here?
Overall, great product nonetheless!

The open-loops part is the bit that stands out to me. Drafting replies is useful, but remembering what needs a follow-up is where email quietly taxes people every day. Curious whether those reminders are purely email-thread based or can pull from Calendar/Granola context too.
Upstream
@vidur_saini We create follow ups on email threads. We also create follow up emails after each Granola meeting, with a summary, action items and recipients added.
What other types of follow ups do you have in mind?
Upstream
@vidur_saini Before generating a follow-up in a given conversation, we also check other conversations to see whether you actually received a reply on the topic before following up. Also, I’m curious to learn what use cases you have in mind for Calendar.
My new favourite email client. Insane how many times I’ve simply hit ‘send’ on an auto reply!

@antoine_sakho1 Love hearing that Antoine! Thanks for your support

@antoine_sakho1 I love that we nailed your voice!
Upstream
@antoine_sakho1 There's nothing better than just clicking send on an auto draft 😌 If there was one thing you could change in upstream, what would it be?
Upstream
@antoine_sakho1 Love to hear it!

@sabir_hussain15 It all depends on your email volume, the types of inbound message you receive, and how often you typically reply to messages.
What are you most common email use cases?

@sabir_hussain15 @jontiret Jon "aka" the agent automation king. This guy would automate his breakfast if he could
Upstream
@sabir_hussain15 It depends on your inbox, but the main savings come from having drafts, triage, and follow-ups ready without prompting from scratch

The human + agent inbox model is interesting - most tools treat agents as a bolt-on to an existing workflow, and it creates friction. Building the inbox around the assumption that agents will be first-class participants from day one is a different design choice. What's the biggest behavioural change you've seen in users when they start treating the AI as a teammate rather than a tool?
Upstream
Very good question Lava! I'd say that the biggest change is that people start delegating much earlier. Instead of opening a thread, reading everything, thinking for a few minutes and then asking AI for help, they immediately pull an agent into the conversation and work from there
Upstream
I would add that people stop complaining about their inbox all the time and actually have a different relationship with it!
Upstream
Yeah, that's a very good point indeed @louislecat
Upstream
@louislecat 100% agree with this
Upstream
@productrambler I just want to jump on one thing:
I couldn't agree more. Putting AI where it doesn't belong is such a bad experience. that's why we took our time before integrating it. We really wanted to add AI where it made a difference, and was actually useful to out users.
