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

Manage customer support and communication directly from Slack. Send and receive emails, tweets and direct messages in Slack. Collaborate effectively on shared email and twitter accounts like support@your.domain without sharing passwords among team members. SharedBox connects to your Twitter account and any email you currently use. You can also get an @in.sharedbox.app email you can setup forwarding to. Twitter mentions, DMs and incoming emails to your connected email or your in.sharedbox.app email gets delivered to your preferred Slack channel. Review with your team and reply once ready. Every account comes with a support site your users can send and manage their support requests from. You get a free supportby.email subdomain and can also use your custom domain. No new installation or application required. Use a tool your team is already familiar with—Slack. Add multiple emails and Twitter accounts to your Slack workspace.
