Email

Email is one of Kuuumba's core blocks, which is why we recommend linking your account at signup. In Kuuumba you can triage your email normally while also using our Signal/Noise filtering and an agent to draft and send emails.

To draft a new email use shortcut c + e

Use j and k to move up and down through your emails. To archive an email and remove it from your inbox, press e.

Multi-account inbox

Kuuumba supports multiple email accounts in a single inbox. Instead of switching between a work tab and a personal tab, all of your accounts flow into one list that you triage in one pass, with the same keyboard shortcuts and Signal/Noise filtering applied across all of them.

To connect another account, go to Settings and add the Gmail or Google Workspace account. When you draft an email, you choose which connected address it sends from.

Kuuumba Mail

Kuuumba Mail is our built-in email provider — fully managed mailboxes that live inside Kuuumba, with no Google account required. A Kuuumba Mail mailbox works exactly like a connected Gmail account in the product: it flows into the same unified inbox, gets the same Signal/Noise filtering, keyboard shortcuts, sharing, and agent access, and can send and receive with any external address.

Because the mailbox is native, there's nothing to link or re-authenticate. Your mail syncs live — new messages arrive in real time — and Kuuumba-managed labels keep thread state consistent across every device you're signed in on.

Create a Kuuumba Mail address from Settings alongside any Gmail accounts. Your addresses all appear in the send-from picker when you draft, so you can mix native and Gmail accounts freely in one workspace.

Signal vs Noise

Kuuumba splits email into Signal and Noise tabs. Signal is where your high-priority emails go, like team member updates and customer feedback. Noise is for emails that aren't crucial to your workflow, such as newsletters and promotions.

To count as Signal in Email, threads have to clear a higher bar than in the Kuuumba inbox: they must be important and not shared with you by someone else. Routine or shared emails won't be there.

You can change senders from signal to noise or vice versa at any time by right-clicking on an email thread.

Sharing

You can forward, cc, and bcc people as normal using Kuuumba's email client, or share an email thread inside the app using the share button.

When you share an email into a new or existing channel, the participants receive a notification in the left-hand panel.

Recipients of a shared email can view the entire thread but can't reply to it. To let someone reply, forward them the email in Kuuumba's email client.

Mentioning

There are several ways to share in an email.

• If you @mention someone in an email, they get added as a recipient.
• If you @mention a document in an email, it gets inserted as a URL link to Kuuumba. The document's permissions also get updated so that anyone with the link can view it.
