Inbox zero tool for multiple channels
Inbox zero on Gmail is easy. Inbox zero across Gmail, LinkedIn, WhatsApp, and Slack is a different problem.
Most inbox zero tools solve for one channel. You get to zero in Gmail and feel good — while 47 LinkedIn DMs, a WhatsApp thread from a warm lead, and three Slack messages from a partner sit unanswered in separate apps.
Cold is built for the reality of how business conversations actually happen. It pulls Gmail, LinkedIn, WhatsApp, and Slack into one inbox and gives you a single place to reach zero — across all of them, every day.
What makes multi-channel inbox zero different:
Reaching zero across multiple channels isn't just about speed. It's about knowing which messages need a real reply, which need a quick acknowledgement, and which can wait. When every channel is in a separate app, that judgement call happens four times — in four different contexts, with four different levels of visibility into the relationship.
Cold unifies the context. You see every thread from a contact in one place — their LinkedIn DM, their email, their WhatsApp message. You make the judgement call once. You reply once. You move on.
What people use Cold for:
Reaching inbox zero across Gmail, LinkedIn, WhatsApp, and Slack in a single session
Prioritising which messages to action first based on relationship value
Getting AI-drafted replies across every channel so triage is fast
Setting follow-up reminders so zero today doesn't mean dropped tomorrow
Knowing when a conversation is truly done versus just quiet
How it works:
Cold pulls every channel into one prioritised inbox. Messages are ranked by relationship strength and urgency — not by which app pinged you last. AI-drafted replies are ready for each thread, personalised to the conversation history across all channels. You work through the inbox once. Everything syncs to your CRM. You close the laptop knowing nothing was missed.
Frequently Asked Questions
Can Cold actually get me to inbox zero across all channels? Yes. Cold unifies Gmail, LinkedIn, WhatsApp, and Slack into one inbox so you can triage and action everything in a single session.
Does reaching inbox zero in Cold mark messages as read in the original apps? Yes. Actions taken in Cold — replies, archive, snooze — reflect in the native app.
What happens to relationships when I archive a conversation? Archiving a conversation doesn't end the relationship. Cold continues tracking the contact and will surface them again when follow-up is due or the relationship starts to decay.
Does Cold help me stay at inbox zero, not just reach it once? Yes. Cold's relationship decay alerts and daily digest surface conversations that need attention before they pile up — so zero is a daily habit, not a one-time event.
Is Cold faster than managing each inbox separately? Significantly. One prioritised view, AI-drafted replies, and cross-channel context means triage that used to take an hour across four apps takes minutes in one.
