    Most reps live in their inbox and copy the important bits into the CRM later. Half of it never makes it. Then the deal record is missing context.

    Lumenbase pulls the inbox into the CRM. Your email links to the right contact and deal automatically.

    The unified inbox

    Lumenbase has a Communication page at `/communication`. It's a sales-focused inbox that connects to Gmail or Outlook/365.

    It gives you:

    So one place holds email, calendar, and LinkedIn for each contact.

    • Threads linked to the matching CRM records
    • Statuses: needs reply, waiting, snoozed, done
    • Compose and send from inside the CRM
    • Two-way calendar sync
    • LinkedIn messages, through the browser extension

    Email linked to contacts and deals

    When email syncs, it lands on the contact's timeline. If that contact is on a deal, the thread shows up against the deal too. You open a record and see the full conversation history without digging through your inbox.

    What you connect

    The inbox runs on the `gmail_calendar_sync` capability. You connect either:

    Calendar syncs both ways, so meetings you book show up on both sides.

    • Google Workspace (personal integration), or
    • Outlook / Microsoft 365

    Why it helps the day to day

    You stop switching between inbox and CRM to keep them matched. Reply from the Communication page, and it logs itself. The deal record stays current because the email lives there too.

    Who this is for

    Revenue operators at $2M to $30M ARR companies who run sales out of their inbox and want it tied to the pipeline. Teams on Gmail or Outlook that hate double entry.
