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.








Early adopter of Upstream and I am a huge fan!
I have tried them all: Gmail AI features, Codex & Claude Code with MCPs, Superhuman. But the only one that really stuck has been Upstream.
My favorite feature is the emails auto draft using my voice! I find myself just pressing send 70% of the time.

@guillaume_miara Thanks for supporting us from the beginning Guillaume!
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.

@jacob_waern This is one of those features that I use almost every day. I'm glad it's been saving you some time!

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!

@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.
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!

@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?
Really loving the product so far! I barely need to adjust the drafts Upstream generates.
The only thing I’d love to see improved is smoother switching between mailboxes without opening a new tab each time.

@vivien_p I'm happy to hear that you're enjoying Upstream! Would a shortcut to switch mailboxes be helpful or do you have another idea of what would work best for you?
@louislecat just when I switch from the top right button to another mailbox that is already open in another window, it opens this window instead of a new one. I often get 6+ windows open.
A keyboard shortcut could be cool too.
Upstream
@vivien_p Got it, so switching mailboxes, but staying in the same tab would be the optimal experience?
Been using Upstream in beta and the drafts genuinely sound like me, not like AI assisted. The reply’s already waiting when I open a thread. Congrats!

@gregoireboutin We love nailing your voice, thanks for being an early supporter!
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.

@benjamin_lalanne1 We appreciate that Benjamin! Also there are quite a few of us in the office that use dictation too 🗣️🗣️🗣️
