Inbox CardinalThe beta
Be one of the first, and help shape it
We are opening Inbox Cardinal to a small first group of people who live across more than one inbox. Beta users join as design partners: you use it on your real accounts, and your feedback directly shapes what we build. We keep the group small so every voice counts.
What you get
Early access, free throughout the beta.
A direct line to the founder. Your feedback genuinely shapes the product; this is not a suggestion box.
Founding-user pricing locked in at launch, as a thank-you for being early.
Your real, messy, multi-account life finally handled, not a demo on sample data.
What we ask
Connect your real accounts; the everyday reality is the whole point.
Live with it for about three to four weeks as your daily "what matters" layer.
Be honest with us, especially when it gets something wrong. A miss or a false alarm is the most useful thing you can give us.
A 15-minute check-in each week, or written notes if async suits you better.
Getting started is quick
1. Say hello
Use the assistant in the corner of this page, or email us. Name and email is all we need; Duane follows up personally, usually within a day or two.
2. Connect your accounts
A few minutes with secure sign-in. Per-account consent, and no passwords shared for Google and Microsoft accounts.
3. Wake up to your brief
Group your accounts into your worlds and your priority feed goes live right away, with your first morning brief the next day.
Ready when you are.
Tell Cardinal, the assistant in the corner of this page, that you want in. Or reach us the old-fashioned way.
