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

Snipe Outbound is a managed outbound prospecting and appointment-setting service for B2B software companies and agencies selling to ecommerce businesses. The team defines target markets, buyer criteria and offers, then prepares research, contact data, sending infrastructure and campaign messaging. It runs cold-email outreach, monitors replies, applies agreed qualification criteria and books sales conversations for the client’s team. Snipe builds a client-owned Market Map and separates campaign sending from the client’s primary domain; clients retain responsibility for discovery and closing. Engagements may include go-to-market positioning and messaging advice. Its audience includes SaaS vendors, ecommerce software providers, conversion-rate optimization agencies, paid advertising agencies and Shopify development firms serving ecommerce brands. It is a managed service, not standalone outbound software.
