About COLOSSALES
Colossales adds a Kanban CRM directly inside Gmail. Sort your conversations into columns, leave internal notes, set reminders, and (with Pro) manage a sales pipeline — without opening another tab.
Salespeople already live in their inbox. Colossales attaches the card, status, comment, and reminder directly to the Gmail thread. No copy-pasting into a separate CRM.
One specific use case: a Kanban CRM inside Gmail, with data stored 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, archived) or a manual card (call, trade show, lead outside email).
• Internal comments attached to the thread. They are never sent to the customer.
• Google Tasks reminders, also visible in Google Calendar depending on your configuration. Included in Free.
• Pro Pipeline: Prospect → Qualified → Proposal → Won, with amount / date / probability fields, companies, contacts (Google Contacts read access), history, Drive files, multi-thread deals, dual TODO + Pipeline boards (editable columns).
• Deal Assistant (Pro, on click): Gemini summarizes and suggests; you decide whether to apply the suggestions. It does not send emails. Local Google AI Studio key.
• Team Plan: Workspace seats, shared Sheets workbook, members assigned to a card, read-only sharing.
DATA
On the first Sync, a “Colossales CRM Data” workbook is created in your Drive. You own it. Scope: drive.file — only files created by Colossales or files you explicitly open. No Google password is stored. No resale of mailbox data.
