The answers teams ask most when they pipeline from Gmail.
Install from the Chrome Web Store (link once published). Private testers: Chrome developer mode. Open Gmail, accept OAuth (Gmail, Sheets, Tasks) — the board appears in the UI.
Confirm the extension is enabled on chrome://extensions, you’re on mail.google.com (not another client), then reload the tab. If OAuth was denied, reconnect from the Colossales panel.
From the Pricing page or the “Go Pro” CTA in the extension. Stripe opens a secure checkout; Pro entitlement activates once payment is confirmed.
In a Google Sheets workbook tied to your Google account. Colossales doesn’t host your pipeline in a proprietary database. See the Privacy page for details.
Free syncs a limited thread volume; Pro goes to 100+. Re-run Sync from the board bar. If Sheets is read-only or over quota, Google may block writes.
Confirm the Tasks scope in OAuth, then create a reminder from a thread’s detail panel. Tasks also show in Google Tasks — check the correct Google account.
Yes. Colossales doesn’t have to replace your enterprise CRM: it structures the inbox. Many teams keep it for triage and live deals alongside the official CRM.
Chrome → Extensions → remove Colossales. Your Sheets data stays in Drive. Pro subscriptions are managed separately via the Stripe portal.
