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!
@aureliengeorget Thanks so much Aurélien! We worked hard on refining the onboarding flow, I'm glad it resonated 😄
@aureliengeorget the onboarding was one of our favorite parts to design!
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 😌
@aureliengeorget Thanks a lot! Happy to hear you really liked the onboarding
