Slack and email unified inbox
The deal moved to Slack. Cold made sure you didn't lose track of it.
Slack was supposed to replace email. Instead it created a second inbox — one with no threading, no follow-up reminders, and no CRM integration. Important conversations happen in Slack channels and DMs every day and then disappear into scroll history, unlogged and untracked.
Cold pulls Slack and email into one unified inbox. Every conversation is attributed to a contact, tracked against the relationship, and synced to your CRM. Whether the thread started in Gmail or a Slack DM, Cold remembers it.
What high-performing users use Cold for:
Reading and acting on Slack DMs and email in one view without switching apps
Tracking relationship history across Slack and email combined
Surfacing Slack conversations that have gone quiet and need a reply
Logging Slack interactions to Attio, HubSpot, or Salesforce automatically
Getting AI-drafted replies informed by the full cross-channel conversation history
How it works:
Cold connects to Gmail and Slack and pulls every DM and email thread into one prioritised inbox. Conversations are matched to contacts automatically. Relationship strength is scored across both channels — so a contact you email regularly but haven't spoken to on Slack in weeks surfaces differently than one you're actively in thread with. Your CRM updates in the background. The conversation stays whole.
Slack as context, not just a channel.
Most tools treat Slack as a message source — something to read and reply to. Cold goes further. When you draft a reply to an email, Cold's AI has already read the Slack thread with that contact. It knows what was discussed, what was agreed, what the tone of the relationship is. The email it drafts isn't informed by the email thread alone — it's informed by everything. A contact you've been casually back-and-forth with on Slack gets a different reply than one you've only ever emailed formally. Cold knows the difference.
Frequently Asked Questions
Does Cold work with Slack channels as well as DMs? Cold focuses on direct conversations — Slack DMs and email threads — where relationship context lives.
Does Slack context improve Cold's AI replies? Yes. Cold's AI reads your full conversation history across Slack, Gmail, LinkedIn, and WhatsApp before drafting a reply. A Slack thread where a contact agreed to an intro, a Gmail chain where you discussed terms, a LinkedIn DM where they first reached out — Cold holds all of it when it writes. The result is a reply that sounds like you know the person. Because Cold does.
Can Cold sync Slack messages to my CRM? Yes. Cold syncs Slack DM conversations to Attio, HubSpot, and Salesforce, attributed to the correct contact record.
Does Cold work with other email providers besides Gmail? Cold connects natively to Gmail. Additional providers are on the roadmap.
