High-volume inbox management tool
Hundreds of conversations. Cold makes sure none of them slip.
At high volume, the inbox stops being a communication tool and starts being a liability. Messages get buried. Follow-ups get missed. The person you most needed to reply to last week is the one you forgot about entirely.
Cold is built for inboxes that never stop. It unifies Gmail, LinkedIn, WhatsApp, and Slack into one view, tracks every conversation automatically, and surfaces what needs attention before it's too late. The more conversations you're managing, the more Cold does for you.
What high-volume users use Cold for:
Managing hundreds of active conversations across channels without a spreadsheet
Automatically tracking which conversations are warm, stale, or overdue
Getting AI-drafted replies that match the tone and context of each thread
Flagging relationships that have gone quiet before they go cold permanently
Syncing every interaction to CRM automatically — no manual logging at volume
How it works:
Cold connects to Gmail, LinkedIn, WhatsApp, and Slack. Every conversation is ingested, attributed to a contact, and scored continuously. As volume grows, Cold's prioritisation gets sharper — surfacing the conversations with the highest relationship value, the most urgency, and the longest silence. You stop managing an inbox. You start managing relationships.
The AI drafts replies in your voice, informed by the full history of every thread. Your CRM stays current in the background. Nothing falls through.
Frequently Asked Questions
