Using a company Google account?
Some companies on Google Workspace block apps their admin hasn't approved. Then Google says "Access blocked: your institution's admin needs to review Inbox Hero" when you connect Gmail. Signing in still works, and your invite stays saved; only the Gmail connection waits for your admin.
Send this to your admin. It takes them about a minute:
Admin console > Security > Access and data control > API controls > Manage third-party app access > Add app > OAuth App Name or Client ID > search for Inbox Hero or paste the client ID below > select it > Trusted. Client ID: 979342705146-37g6jj5cccfpjr9ji24fdg14bh09cj0j.apps.googleusercontent.comEmail my admin
Once they've allowed it, sign in with Google.
Other ways in today
- Sign in with a personal Gmail instead (pick another Google account on the next screen).
- Sign in with your email, then connect your mailbox with IMAP and an app password, if your company allows it.
