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.








I’ve been using Upstream and what really stands out is how natural the drafts feel — they actually sound like me, not like a generic AI reply. Opening a thread and already having a solid response waiting there saves a surprising amount of time. The follow-up nudges are also genuinely useful for keeping important conversations from slipping through the cracks. Congrats on the launch — this is one of the few AI email tools that feels built for real daily use.

@greg_lpz Thanks so much Grégoire!! Are there any features that would help make AI replies even better for you?
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!

@johan_p_ Thanks a ton Johan! We really appreciate it. Let us know if there are any features that would make things easier.
Been using Upstream for a few months now and I can’t imagine going back to Gmail. The UX is so much better, and the inbox splits have made managing my emails so much easier

@delphy_rodriguez So glad you're enjoying Upstream 😄 we appreciate your support
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!
