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.
Replies
Great time-saver. Particularly value the 'Follow Ups' feature which surfaces emails requiring a follow-up, including the actual wording so you can just press send. These get totally lost in gmail.
Upstream
@jacob_waern This is one of those features that I use almost every day. I'm glad it's been saving you some time!
Upstream
Upstream
@jacob_waern Completely agree! And one of the followup features is the agent knows when to remind: if you tell someone "please reply ASAP", you'll get a follow-up the next day. If you say instead "i need your reply before the end of the week", you'll get a followup on thursday/friday. This makes the feature much more useful!
Upstream
@skwph That's one of my favorite parts too. also what I really like is that before reminding me to follow up, the agent checks other related threads to see whether the person already got back to me somewhere else. It sounds simple, but it avoids a surprising number of unnecessary follow-ups 😅
@jacob_waern what kind of conversations do you use it for most often?
Upstream
@jacob_waern this is one of those features that makes me glad every time I see a new follow up
Upstream
@jacob_waern happy to hear that the followups help! Was fun to work on this :)
love it! will easily replace my Superhuman subscription

@amaury_sepulchre2 Love to hear that 💪

@amaury_sepulchre2 🙌🏾🙌🏾
Upstream
@amaury_sepulchre2 Thank you! Did you know about our team features? they were actually the hardest part to build because email is meant to be personal, not shared. Thanks to them, upstream became the slack for email to me!
Upstream
@amaury_sepulchre2 best signal we can get, thanks!
One of the first time I am actually able to switch immediately without going back and forth to Gmail to complete a task. Very very neat !
Upstream
@julienalart Less context switching and more focus! Thanks for your support 😊
Upstream
Upstream
@julienalart that was super important for us when building :)
Upstream
@julienalart @amperisk It was so important you even designed the whole product such that people wouldn't be lost coming from GMail. So much thinking and efforts went into this design!
Upstream
@julienalart @amperisk @skwph tt’s surprisingly hard to make something feel new without making people relearn everything 😅
Upstream
@julienalart Thanks Julien! Really happy to hear that 🙌

Been using it a few weeks and it cut my inbox time roughly in half, and the drafts really sound like me. This is really cool. Congrats on the launch!
Upstream
@gregcha So glad you've ben liking the drafts and have been saving time. Let us know if there's anything else you'd like to see/do in Upstream.

@gregcha thanks for all of your support!

@gregcha Thank you Grégoire, it means a lot!

The interesting problem with a shared human/agent inbox isn't the UI, it's attribution and handoff. When an agent drafts or sends something on my behalf, I need to know exactly what it touched, what it decided autonomously versus what it queued for my review, and what happens when I disagree with a choice it already made. Does Upstream have a clear model for that, or is the agent more of a drafting assistant that still requires explicit approval before anything goes out? Also curious whether this is built on top of existing mail providers like Gmail and Outlook, or whether you're asking people to route actual email through a new address.
Upstream
@fberrez1
We totally agree that control and final decision should remain in your hands. The agents work for you and nothing gets sent without your approval. Upstream works with your existing gmail address and keeps everything in sync with your Gmail account.
TBH I find the attribution/handoff problem fascinating, especially as agents are going to gain in capability. Do you have a take on what the right approach should be here?
Upstream
+1 to what you said @fberrez, as a developer who uses agents every day, the question of security or risk when you give too much power to agents is something that obsesses me. So for me, it was extremely important that users always approve their actions and it'd say it’s a very strong principle for Upstream
I got hooked! My productivity went up massively, my mail box is always empty, auto-draft feature is the best out there - it matches my tone very well - and the keyboard commands make it feel so good. Big congrats guys!
Upstream
@arthur_taubner Wow! Love hearing how much Upstream has been helping your workflow. Thanks for the support :) Are there any other features that would make your life easier?
Upstream
Upstream
@arthur_taubner 🙌🏾🙌🏾 thanks so much Arthur!
Upstream
@arthur_taubner thank you Arthur, it means a lot 😌
Upstream
@arthur_taubner thanks a lot!
I’ve been using Upstream for a few weeks, and it genuinely gave me time back, which not many tools actually deliver on.
Upstream
@gabriel_hofman That's amazing to hear! Are there any features that could save you even more time?
Upstream
Upstream
@gabriel_hofman 🙌🏾🙌🏾
Upstream
@gabriel_hofman Agree, it's damn hard to replace GMail, let alone improving on it. So happy we got it right! Thank you so much Gabriel!
Upstream
@gabriel_hofman thanks Gab!
Makes me love email again 😍

@cedric_roux love hearing that Cédric!

@cedric_roux so happy to hear this!

@cedric_roux Thank you so much Cedric
Daily driver here. Dictation mode lets me just talk and it writes. And "needs reply" is brilliant: the draft is already there waiting, so I'm never staring at a blank page, but I stay in control of what actually sends. Rare to find AI email that assists without taking over. Congrats to the team.
Upstream
@benjamin_lalanne1 We appreciate that Benjamin! Also there are quite a few of us in the office that use dictation too 🗣️🗣️🗣️
Upstream
Upstream
@benjamin_lalanne1 Staying in the driver's seat is the key to Upstream. Emails are so critical we can't just let an LLM/agent send some without control. I'm super happy you like Upstream!
Upstream
Well said @skwph . We want people spending less time writing emails, not less time making decisions
Upstream
@benjamin_lalanne1 this makes me very happy to read. Thank you!
Upstream
@benjamin_lalanne1 Love that dictation and "needs reply" are clicking for you, Benjamin - thank you!

Certainly the most promising email client in a while!! The onboarding will blow your mind, it feels like Upstream has been knowing you forever, and it writes emails exactly like you. Emails are cool again!
Upstream
@aureliengeorget Thanks so much Aurélien! We worked hard on refining the onboarding flow, I'm glad it resonated 😄
Upstream
Upstream
@aureliengeorget the onboarding was one of our favorite parts to design!
Upstream
That's exactly what we wanted: to make you feel at home. To make you feel like upstream understands your business and is able to reply in your voice. I'm so glad you liked it 😌
Upstream
@aureliengeorget Thanks a lot! Happy to hear you really liked the onboarding
