WhatsApp and email inbox manager

Your most important conversations are on WhatsApp. Your CRM has no idea.

WhatsApp is where relationships get real. It's where investors text you after a meeting. Where a candidate says yes before the formal offer. Where a partner closes the loop after a call. It's also completely invisible to every CRM, inbox tool, and sales platform on the market.

Cold fixes that. It unifies WhatsApp and email into one inbox, attributes every conversation to the right contact, and keeps the full relationship picture in one place — not split between your phone and your laptop.

What high-performing users use Cold for:

• Reading and replying to WhatsApp and email without switching apps
• Tracking the full relationship history across both channels in one view
• Getting AI-drafted replies for WhatsApp threads informed by email context — and vice versa
• Automatically syncing WhatsApp conversations to Attio, HubSpot, or Salesforce
• Knowing when a WhatsApp contact has gone quiet and needs a follow-up

How it works:

Cold connects to your Gmail and WhatsApp accounts and pulls every conversation into one unified inbox. Messages are attributed to contacts automatically. Relationship strength is scored across both channels combined — so a contact you email weekly but haven't WhatsApped in a month shows up differently than one you're actively texting. Everything syncs to your CRM. Nothing stays siloed on your phone.
