CampaignStack with the tools you already run

None of these are competitors. Claude and ChatGPT are the assistants the product is driven from and the models it writes with; Clay, HubSpot, Instantly, Apollo, n8n, Zapier and Make are tools that run next to it and connect over an API key or a webhook. Each page says what the tool does on its own, what it cannot do alone, and how the two run together.

What we run on

CampaignStack with Claude

Claude already writes the message. Connect the MCP server and it can also source, score, send inside safety budgets and stop when someone books.

What we run on

CampaignStack with ChatGPT

Switch on developer mode, paste the server URL, approve the connection, and ChatGPT can source, score, draft and send inside the same budgets and review gates as the app.

Runs alongside

CampaignStack with Clay

Clay builds and qualifies the row. Wire a Clay table into a workflow's webhook source, push worked leads back into a table, and run a Clay routine as an enrichment step.

CampaignStack with n8n

An n8n workflow pushes leads into a CampaignStack workflow over a signed webhook, a webhook step posts back out, and an n8n AI agent drives the MCP server with a key.

CampaignStack with Zapier

A Zap posts leads from any of 9,000 apps into a workflow's webhook source, and a webhook step in CampaignStack triggers a Zap the moment a lead replies or books.

CampaignStack with HubSpot

A CRM sync step upserts the lead as a contact, associates its company and logs every outreach message as a note on the timeline; portal contacts and lists import as leads.

Runs alongside

CampaignStack with Instantly

An add-to-sequence step hands the lead to the Instantly campaign you already run, replies and bounces flow back through the webhook, and SuperSearch runs as an enrichment provider.
