CampaignStack is campaign orchestration for B2B lead generation agencies running outbound at volume across LinkedIn and email.
The design starts from the constraint everyone else ignores: a client's LinkedIn account is not replaceable. So every connected account gets a hard daily action budget that ramps up over weeks instead of firing at full volume on day one, a dedicated residential proxy, and a persistent browser fingerprint that stays stable between sessions. The numbers are visible in the dashboard, not buried in a settings page.
AI drafts the messages. A human approves them in a review queue before anything leaves the account, and auto-send stays off until you switch it on.
Underneath, leads are scored against your ICPs, signals like job changes and post engagement decide who is worth contacting, and replies land in one shared inbox. An MCP server with 90+ tools lets Claude and other AI agents drive the whole platform.

CampaignStack runs on a TypeScript stack end to end.
CampaignStack protects the one asset in outbound that cannot be replaced: the client's LinkedIn account. Once it is restricted, no amount of spend brings it back.
Against tools like Expandi, Dripify, Waalaxy, HeyReach, Skylead, and Dux-Soup, which compete mainly on volume and speed:
Everything else is still there: campaign orchestration, ICP scoring, buying signals, A/B testing, and one shared inbox across every account and client.
CampaignStack is a LinkedIn and email outreach platform built around one rule: show the sending limit, and refuse to cross it.
Most tools in this category bury their limits in a settings page. CampaignStack puts the number on the dashboard.
CampaignStack is built for B2B lead generation agencies running outbound for several clients at once, sized for 5 to 20 client workspaces, where one restricted profile means a lost retainer.
It also fits:
All of them share one constraint: they need volume, and they cannot afford to lose an account getting it.
CampaignStack is built by a small team that spent years inside the LinkedIn automation industry, watching client accounts get restricted by tools that sent too much too fast. The pattern was always the same: the tool advertises volume, the agency turns it up, and a few weeks later a client's account is limited and the retainer is gone. Nothing on the market showed you the line you were about to cross. So we built the platform we wanted to use, one that treats a connected account as something you cannot get back.
