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!
@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?
@antoine_sakho1 Love to hear it!
Great product!
I've been using it for a few weeks and I find myself in my inbox more than usual!
Great auto-complete and I've been using the label features a lot!
@andrei_a1 We appreciate you using the product day in and day out!
@andrei_a1 thanks so much! Keep sending feedback it helps us improve very quickly :-)
@andrei_a1 so glad you’re enjoying the product!
@andrei_a1 Thank you so much Andrei! Did you have the chance to try our team features? 😁
@andrei_a1 Appreciate it. "In my inbox more than usual" is a funny but very good signal
@grey_seymour Feel free to leave us any feedback!
@grey_seymour excited for you to try!
Looking forward to getting your feedback Grey!
@grey_seymour Shortwave has been an inspiration for us. I'm so happy to see us being compared with them 🥰
@grey_seymour Shortwave is great - curious to hear how Upstream feels for you after testing
Use it myself, the AI assistant is simply better than Superhuman!
@phillip_baek Thanks a lot Phillip!
@phillip_baek thanks so much Phillip!
Thanks so much @phillip_baek
It means a lot
@phillip_baek Thank you so much Philip! I'm so happy you love it! And we're going to improve it a lot, so many things on the roadmap... 🔥
@phillip_baek That's high praise, Phillip - thank you! Means a lot coming from a Superhuman user.
I have too many email accounts. Plural. And they are all overlapping and somewhat out of control (honesty here). This allows me to scan them easily and action on what needs actioning without it being a total headache. Thanks for creating something so user-friendly as well as accurate to my own voice!
This is exactly the kind of user we had in mind @katherine_fye_sears1 😅
And honestly, "somewhat out of control" describes a lot more inboxes than people are willing to admit haha
Out of curiosity, how many accounts are we talking about here? And are they mostly work accounts, personal accounts … ?
@katherine_fye_sears1 Thank you so much Katherine! the user friendliness was a day-1 requirement for us. We couldn't imagine building "yet another" boring email client. @amperisk worked really hard to design the product around it, and he did an amazing job!
Thank you@katherine_fye_sears1, that's the kind of feedback we strive for day in day out!!!
@katherine_fye_sears1 So glad it's taming the multi-account chaos, Katherine! 🙏 Thank you for the kind words - that's exactly what we hoped it would do.
Hey PH — Patryk here, one of the builders behind Upstream.
The part I’m most proud of is that Upstream is not just another AI summary layer on top of email. The goal is to help people actually get through conversations: triage, draft replies, adapt tone, and never lose important follow-ups.
We’ve been using it internally while building it, and it already changes how email feels day to day.
Happy to answer questions about the product, agents, privacy, or how it compares to other email clients.
@patryk_jeziorowski So happy to have you on board Patryk!
@patryk_jeziorowski @skwph Congrats for making it to #1 Product of the day 🙌🙌🙌🙌
For those wondering, @patryk_jeziorowski is one of the people responsible for a lot of the magic happening behind the scenes 🫡
@hugues_lecat So glad Upstream has been apart of your daily workflow and saved you a ton of time ⏱️
@hugues_lecat thank you!
@hugues_lecat thank you so much Hugues! If you could change one thing about upstream, what would it be?
@hugues_lecat that means a lot, Hugues. Thank you 🙏
