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
PureMail provides managed Google Workspace and Microsoft 365 email inboxes for teams running cold-email outreach. Customers supply their own domains and select an inbox volume; PureMail provisions mailboxes, configures SPF, DKIM, DMARC and MX records, and connects accounts to sending platforms such as Instantly, Smartlead, Lemlist and other sequencers. Plans are billed monthly per inbox, with volume-based rates, DNS setup and integration included and no setup fee. Accounts include mobile and web access, while support is available through dashboard tickets. PureMail is intended for lead-generation agencies, B2B sales teams, SDRs, founders and other outbound teams that need multiple business email inboxes. The company also publishes a cold-email tool directory with provider pricing, sending limits and rubric scores.
