Description
GrowZen is an all-in-one cold email outreach and deliverability platform that runs the entire outbound workflow in a single app. It is a session-stable desktop application for Windows and macOS (not a browser extension) that runs real Chrome profiles locally for isolated Gmail automation while handling cloud SMTP sending, with a web dashboard for monitoring campaigns, replies, and analytics.

GrowZen covers each part of outbound: scraping targeted leads from Google Maps, Google Search, Yellow Pages, and website crawls, plus a built-in 228M+ B2B lead database with Apollo-style filters and verified emails on reveal. Every list runs through 4-layer verification (syntax, MX, DMARC, and a live SMTP probe with catch-all detection), and a built-in 28-day warmup ramp, human-like sending delays, per-account limits, browser-profile isolation, and bounce auto-pause keep sending accounts safe. Multi-step sequences send from the cloud across warmed accounts, and the Smart Zen Unibox unifies replies with intent labels and AI-drafted responses.
The platform is powered by Zen, an assistant built on the Zen Brain that learns a user's business from uploaded docs, personalizes copy, answers leads, reads metrics, and can run the funnel autonomously. GrowZen connects to n8n, Zapier, Make, and GoHighLevel via HMAC-signed webhooks, and to Claude, ChatGPT, and Cursor via an MCP server, with bring-your-own-key support for Anthropic, OpenAI, Google, and DeepSeek. A free trial is available.
