Superhuman for DMs

Cold unifies your LinkedIn, WhatsApp, Slack, and email DMs into one AI-powered inbox — so sales reps respond faster, follow up smarter, and close more deals.

The AI-Powered Inbox for Sales DMs

Sales conversations happen across LinkedIn, WhatsApp, Slack, and email — but most sales reps are managing them across four separate apps with no context, no system, and no AI. Cold is the unified, AI-powered DM inbox built for sales professionals who need to respond faster, follow up consistently, and turn more conversations into closed deals.

Why Sales Reps Lose Deals in Their DMs

Direct messages are the highest-intent channel in modern sales — but they're also the most fragmented. Without a unified view, warm conversations go cold, follow-ups get missed, and context is lost between threads.

Common problems Cold solves:

  • Scattered conversations across LinkedIn, WhatsApp, Slack, and Gmail

  • No conversation memory — re-reading threads to get back up to speed before every reply

  • Slow response times — drafting thoughtful messages manually takes time

  • Missed follow-ups — no system to track who needs a reply and when

  • Zero CRM sync — DM conversations never make it into your pipeline

One Inbox. Every Sales Channel. Powered by AI.

Cold brings all your direct messages into a single, AI-powered workspace — with full context, smart drafting, and automated follow-up tracking built in.


Unified Sales Inbox Connect LinkedIn, WhatsApp, Slack, and Gmail. See every conversation in one place, filtered by channel, contact, or deal stage. No more tab-switching.


AI Inbox Copilot Cold's Inbox Copilot sits alongside every thread with full memory of your past conversations, associated deals, and relevant documents. Ask it questions, pull context, or get a draft reply — without leaving the message.


AI-Drafted Replies, In Your Voice Tell Cold what outcome you want, and it writes the message. Or let it draft based on thread history and contact context. Faster replies that still sound like you.


Automated Follow-Up Tracking Cold surfaces open threads that need attention so nothing slips. Set follow-up reminders or let Cold flag conversations that have gone quiet.


Full Conversation Memory Across Channels Ask Cold to "summarise my conversations with [Contact]" and get a clear brief — pulling from LinkedIn, WhatsApp, Slack, and email — before any call or meeting.


CRM Sync Conversations feed directly into your pipeline. Cold creates and updates deals in HubSpot or Attio based on what's happening in your DMs.
