CampaignStack vs Clay, n8n and a sequencer: the honest comparison
Most lead-gen agencies are not choosing between CampaignStack and one competitor. They are choosing between CampaignStack and the stack they already run: Clay for enrichment, n8n for the glue, Lemlist or Instantly or HeyReach for the sending, and someone on the team who keeps it wired. Each of those tools is good at its own job. This page is about the space between them, where nobody is on call.
You need enrichment logic nobody sells off the shelf, you have someone who likes maintaining it, and flexibility matters more than uptime. Clay's provider waterfalls go deeper than any built-in enrichment step. n8n will call any API you can name, and self-hosting it means no vendor can switch your automations off. If that is you, keep it.
What keeps breaking is the handoff, not the tools. One system holds the lead from sourcing through enrichment, drafting, review, sending and the reply, so nothing falls between two vendors. The safety budgets, the review queue and the reply router read the same lead state the send step reads, and when a scheduled job stops firing you get told.
Where the work actually lives
Competitor prices and capabilities come from each vendor's own public pricing page, checked August 2026. CampaignStack rows describe what is built today, not the roadmap. Where the DIY stack is better, the cell says so.
| Capability | Clay + n8n + sequencer | CampaignStack |
|---|---|---|
| Enrichment waterfalls | Clay is best in class: many providers per column, fallback chains, and per-provider credit control that no built-in step matches | An enrichment step calls Apollo or Instantly in a set order and writes contact details onto the lead. Useful, but not a waterfall builder |
| Arbitrary integrations | n8n calls any API, runs your own code, and self-hosts. If a tool has an endpoint, you can wire it | A fixed catalog of workflow nodes, plus a webhook step, a CRM sync step and push-to-sequence and push-to-list steps for outside tools |
| LinkedIn account safety | The sequencer caps its own sends. Clay runs and n8n loops that also touch a profile sit outside that count, and nothing reconciles them | Per-action daily budgets, usage-based warm-up, weekly invite caps, business-hours pacing, and an automatic pause on the affected action family after a risk signal |
| One state per lead | Three systems each hold part of the lead's state, and which one is right depends on which ran last | Sourcing, enrichment, drafting, review, sending and the reply are steps in one workflow over one lead record |
| A reply stops the queued follow-ups | The sequencer stops its own sequence. A follow-up already queued in n8n or in a second campaign keeps going | An inbound reply cancels the lead's unsent touches across the workspace before the conversation is handed to the responder |
| Duplicate-touch prevention | Two workflows can both claim the same lead, and nothing arbitrates between them | Entries are deduplicated at intake, and dispatch re-reads the lead's state before every send so a touch queued yesterday does not go out after the situation changed |
| AI drafting | An LLM node writes the message, and whatever came back is what ships | Every lead-facing draft is written against your playbook and offer facts, then read by a critic that objects and forces a rewrite |
| Human review queue | None of the three tools has one. Reviewing means opening a table and reading rows | A queue where you approve, edit, retry or reject, and approving resumes the exact action that was held back |
| Silent breakage | n8n shows you executions that failed. A schedule that quietly stopped firing produces no error to look at | Every tracked background job alerts on repeated failures and on no success within twice its expected gap, which is the case that throws nothing |
| Portability | Self-hosted n8n is yours, your Clay tables export, and no vendor can switch you off | Workflows export as versioned JSON and lead lists export as CSV, but the runtime is ours |
| Driving it with an AI agent | Each tool has its own API, so an agent has to speak three of them and carry the state in between | One MCP server exposes the platform, so an agent can source, score, draft, review and send through a single interface |
| Pricing model | Three or four subscriptions plus credits plus the person maintaining it. Published numbers are in the section below | $299 per workspace monthly, or $2,988 a year. Credits cover usage, and connected LinkedIn accounts are not seats |
What the DIY stack does better
Clay's enrichment is excellent and we are not trying to clone it. Provider waterfalls with per-provider cost control, on top of conditional columns, is a product CampaignStack does not have. If your edge is a lookup nobody else runs, Clay is where you build it.
n8n's ceiling is real too: anything with an endpoint, plus whatever code you write yourself. Self-host it and nobody can take it away. A fixed node catalog will always be narrower than a general automation engine, and pretending otherwise would be a lie you noticed in week two.
Then there is the cost of already knowing it. You built this stack. The playbooks are in your head, your team can debug it at 11pm, and switching has a price. Any comparison that leaves that out is selling.
Nobody owns the space between the tools
Each tool is accountable for its own step and nothing else. Clay hands off enriched rows. n8n hands off a webhook. The sequencer sends. When something goes wrong between two of them, both vendors' status pages are green and both support teams are correct.
The failures are always the same four. A lead that got enriched and never entered a sequence, because the webhook returned 200 and the row was dropped downstream. A reply that landed in a sequencer nobody watches, so a follow-up went out three days later as if the person had said nothing. An account that hit a limit at 2am and kept being handed work by a workflow with no idea what a limit is. A lead touched twice because two workflows both had a claim on it.
None of those are bugs in Clay, n8n or the sequencer. They are seams. CampaignStack does not have them because there is nothing to hand off: one workflow graph moves the lead, and the safety budgets, the review queue and the reply router read the same lead state the send step reads.
What the stack costs, with published numbers
Clay's Launch plan is $167 per month billed monthly, or from $54 per month billed annually. Growth is $446 per month billed monthly, or from $185 per month annually, before expanding actions or data credits. n8n Cloud lists Starter at 20€ per month billed annually, Pro at 50€ and Business at 667€, while the self-hosted Community edition is free if you run it yourself. Lemlist's Multichannel plan, the one that includes LinkedIn steps, is $109 per seat monthly or $87 annually. All read from those pricing pages in August 2026.
Depending on the tiers you actually need, that adds up to anything from below CampaignStack's $299 per workspace per month to several times it. Clay's entry tier plus self-hosted n8n plus one sequencer seat is cheaper than we are. Clay Growth plus a handful of sequencer seats is not.
The line nobody puts in the spreadsheet is maintenance. Every provider change, every LinkedIn layout change and every schema tweak in one tool becomes a change request in the other two. That cost arrives as hours instead of an invoice, which is why the cheapest-looking column on a pricing page is rarely the one you end up paying.
You do not have to rip anything out
The usual move here is not a migration. One system takes over the outreach half, and the enrichment half stays exactly where it already runs.
A webhook step in any CampaignStack workflow posts the lead wherever you want, including into an n8n workflow, and n8n can drive CampaignStack back through its MCP server with an API key. Push-to-sequence and push-to-list steps hand a scored, drafted, approved lead to Instantly or to one of your own lists, and Apollo and Instantly connect as enrichment providers inside the workflow graph.
What changes is where the lead lives while it is being worked. Safety limits, drafts, the review queue and reply handling stop being four tools' problems and become one system's.
CampaignStack vs the Clay and n8n stack: common questions
Is CampaignStack a Clay replacement?
No. Clay is an enrichment and data platform, and its waterfalls go deeper than anything built into CampaignStack. What CampaignStack replaces is the glue and the outreach half: the workflow engine, the account safety limits, the drafting, the review queue and the reply handling. Running both is a reasonable setup.
Can I keep n8n?
Yes. A webhook step in any workflow posts to an n8n endpoint, and n8n can call back into CampaignStack through its MCP server with an API key. What changes is n8n's job: moving data between systems rather than being the place a lead's state lives.
Is the DIY stack cheaper?
Sometimes. Self-hosted n8n plus Clay's entry tier plus one sequencer seat comes in under $299 per workspace per month. Clay's Growth tier plus several sequencer seats comes in well over it. The variable nobody prices is maintenance, and it gets charged in your team's time.
What actually breaks in a Clay plus n8n plus sequencer setup?
The handoffs. A lead enriched but never sequenced. A reply that arrives while three follow-ups are still queued somewhere else. A LinkedIn account that hit a limit while a workflow kept feeding it. The same person contacted by two campaigns. In each of those, every tool did its own job correctly.
If I move to CampaignStack, can I get out again?
Your structure and your data come with you: workflows export as versioned JSON, lead lists export as CSV. The runtime does not, because a CampaignStack workflow only runs on CampaignStack, the same way an n8n workflow only runs on n8n. Self-hosted n8n is more portable than we are, and that is a fair reason to pick it.
