We make cold email simple
We built KanbanStack because sending cold emails shouldn't require a 10-step setup guide. You should be able to upload contacts, let AI write the emails in your voice, and track who replies — all in one place.
Why a board for emails?
Most email tools hide your contacts behind complicated tables and menus. You can never really see what's going on at a glance.
With KanbanStack, every contact is a card on a visual board. Cards move automatically when someone opens your email or replies: New → Sent → Opened → Replied → Interested → Closed. You always know where things stand without clicking through anything.
AI that sounds like you
Paste one email you wrote before. The AI picks up your style and writes every new email the same way — no robotic templates.
Send from multiple accounts
Connect your Gmail or Outlook accounts. We spread emails across them so you don't send too many from one place and end up in spam.
Your emails stay safe
Each email is slightly different so it doesn't look like bulk mail. We also filter out fake opens so you only follow up with real people.
