What is ColdStack?

Don’t let valuable opportunities pass you by during the critical two-hour window between a lead's reply and your response. ColdStack aggregates all cold email replies from services such as Instantly, Smartlead, and EmailBison into a singular, dedicated Slack channel, enabling your team to respond swiftly and efficiently.

With each reply, you'll receive immediate notifications that include detailed engagement metrics, such as who opened the email, when it was viewed, and how often it was accessed. This allows your team to seamlessly reply directly within Slack, while ColdStack guarantees that all conversations are synchronized with your original platforms, removing the need to toggle between multiple dashboards and email clients.

Tailored for cold email agencies and sales teams using Slack, ColdStack also provides mobile access through Slack's app, ensuring that your team can maintain communication effortlessly while on the move. By streamlining your workflow and boosting your response rates, ColdStack helps you capture every potential lead, making it an essential tool for enhancing productivity in your sales process. Ultimately, this integration helps to create a more cohesive and effective team dynamic.
