Overview

Email Kanban inside Gmail with Google Sheets (comments and reminders).

Colossales adds a Kanban CRM inside Gmail. You sort conversations into columns, leave internal notes, set a reminder, and (on Pro) run a pipeline — without opening another tab. Salespeople already live in their inbox. Colossales sticks the card, status, comment, and reminder to the Gmail thread. No copy-paste into a parallel CRM. Single purpose: a Kanban CRM inside Gmail, with data in your Google Sheets. This is not a Google Workspace Marketplace add-on: it is a Chrome Manifest V3 extension. FEATURES • TODO board (Free): To do, In progress, Waiting, Done — or your own columns. Each card is a real thread (inbox, sent, archives) or a manual card (call, trade show, off-email lead). • Internal comments stuck to the thread. They are not sent to the customer. • Google Tasks reminders, also visible in Calendar depending on your setup. Included on Free. • Pro pipeline: Lead → Qualified → Proposal → Won, amount / date / probability fields, companies, contacts (Google Contacts read), history, Drive files, multi-thread deals, dual-board TODO + Pipeline. • Deal assistant (Pro, on click): Gemini summarizes and suggests; you apply. Does not send emails. Local Google AI Studio key. • Team plan: Workspace seats, shared Sheets workbook, members on a card, read-only sharing. DATA On first Sync, a “Colossales CRM Data” workbook is created in your Drive. You own it. Scope drive.file: only files created by the extension or that you open. No Google password stored. No resale of mailbox data. PLANS (pricing: https://www.colossales.com/en/pricing/) Free: TODO, comments, Tasks reminders, last 30 threads, manual cards. Pro: pipeline, dual-board, companies, contacts, history, deal fields, multi-thread, statuses, Drive, assistant, expanded sync. Team: everything in Pro per seat, shared Sheets, Workspace sharing. Stripe payment on colossales.com. No Chrome Web Store in-app purchase. License = Google OAuth email. INSTALLATION 1. Add Colossales to Chrome. 2. Open Gmail with the licensed account. 3. Colossales icon in the left Gmail rail. 4. Authorize Gmail, Sheets, Tasks, Contacts (Directory if Team admin). 5. Pin the extension. 6. Sync, then drag a card. Help: https://www.colossales.com/en/help/ Support: https://www.colossales.com/en/support/ Privacy: https://www.colossales.com/en/privacy/ PERMISSIONS (details: privacy policy above) identity / email: license. storage: local settings. Gmail: board and threads. Sheets + Drive: CRM workbook. Tasks: reminders. Contacts read: panel. Directory: Team seats. colossales.com: subscription, sharing, install ping (version only). FAQ Board not showing? chrome://extensions → enabled, reload Gmail, reconnect OAuth. Access denied? In GCP Testing, only an allowlisted tester can authorize the app. Removing a card from the board does not delete the email. Multiple mailboxes: if they are visible in Gmail, sync indexes them. Colossales: your pipeline, without leaving Gmail.
