About

Stop losing deals in the 2-hour window between lead reply and your response. ColdStack brings every cold email reply from Instantly, Smartlead, and EmailBison into a single Slack channel where your team can see and act instantly. Each reply triggers a real-time notification with full engagement context—who opened what, when, and how many times. Your team replies directly from Slack, and ColdStack syncs everything back bidirectionally to your source platform. No more toggling between dashboards, Gmail, and Slack. Built for cold email agencies and sales teams who live in Slack. Mobile-ready through Slack's app.

About

​EmailBison is a white-labeled, privately hosted email sequencing software designed specifically for agencies aiming to supercharge their deliverability. It allows users to host their own email sequencing platform on dedicated servers with isolated IPs, ensuring optimal network isolation. The platform offers powerful email sequencing with multi-step touchpoints, enabling comprehensive outreach strategies. Users can conduct AB split tests for every step of their sequence to determine the most effective email copies. EmailBison supports unlimited workspaces, providing complete data isolation for every client, and offers unlimited contact storage with fully automated statuses. Built-in contact verification ensures that contacts are valid before initiating outreach campaigns. To further enhance isolation, the software supports multiple dedicated sending servers. Custom tags allow for efficient tagging and filtering of contacts based on user-defined criteria.
