ColdIQCampaignStack vs ColdIQ, compared for agencies
ColdIQ put 42 data providers and more than 700 endpoints behind one API key, one credit balance and an MCP server, then published benchmarks measured on real contacts so you can see which provider actually wins. If you are building your own revenue engine inside Claude Code, that is the best shelf of parts you can buy. The engine is not on the shelf. Nothing holds a LinkedIn session, meters what an account can safely do today, decides who is worth contacting, or reads a draft before it goes out. Here is the honest side by side.
You want to build the system yourself and you want the best inputs to build it from. One key across 42 providers, credits charged per identified person or company and never for setup or reads, unused credits rolling over for three months, and a benchmark leaderboard run on 53 real sales contacts rather than vendor marketing. The provider routing and the published test methodology are real work nobody else in this set has done. If your team is comfortable writing the orchestration, ColdIQ replaces 40 procurement conversations with one card on file.
You want the orchestration to already exist. Accounts that stay connected through an encrypted browser profile, daily budgets and warm-up curves per action type, ICP scoring and live signals picking who gets contacted, a critic reading every AI draft before a prospect does, a review queue for the doubtful ones, and a shared inbox for the replies. All of it drivable from the same agent, through an MCP server with over 300 tools.
What each tool actually does
Capabilities as documented by each vendor, checked August 2026. The two products sit on different layers, which is why several rows below split rather than score.
| Capability | ColdIQ | CampaignStack |
|---|---|---|
| Data provider breadth | 42 providers and more than 700 endpoints on one key, with automatic routing between them and credits charged only on an identified person or company | Our own LinkedIn profile and company reads, plus funding, news, hiring and headcount tracking; contact enrichment routes to Apollo or Instantly once you connect them. Not a 40 vendor waterfall |
| Published provider benchmarks | 19 mobile finders tested on 53 real contacts across 15 companies, weighted on accuracy, coverage, price and speed, with statistical ties called out | We publish none |
| LinkedIn outreach | Unipile's 60 endpoints are resold through the marketplace, so invitations and messages can be sent by code you write; there is no campaign, no schedule and no sequence around them | Connection requests, messages, InMail and engagement through a persistent cloud browser per account, inside a workflow graph |
| Native email sending | Instantly's 147 endpoints and Lemlist's 38 are resold, so you drive whichever sender you already pay for; ColdIQ itself sends nothing | Gmail sending with its own daily budgets and warm-up, in the same workflow as the LinkedIn steps |
| LinkedIn session handling | Not its layer; whichever provider you route through holds the session, and the custody question moves to them | Session cookie is consumed into an encrypted browser profile on our server and never stored in the database |
| Account safety limits | Credits meter what you spend, not what an account can survive; no daily caps, warm-up curve or pause on a rate limit | Per-action-type daily budgets, usage-based warm-up, weekly caps, business-hours pacing, automatic risk pause |
| Buying signals | Funding, hiring and intent endpoints from PredictLeads, Signalbase and LinkUp; you poll them, store the answers and decide what changed | Job changes, title changes, post engagement, funding and headcount changes are detected on a schedule and feed campaign scoring |
| ICP scoring | An ICP Definer skill and ICP matching on some list building endpoints; no score that lives on a record and gates who gets contacted | Every lead is scored against every campaign's ICP, and the score decides campaign membership |
| AI-drafted messages | A skills library of copywriting and sequence prompts your agent runs on demand; nothing drafts inside a running campaign | Openers, follow-ups and inbound replies drafted against your playbook, the lead's live context and the sender's own voice |
| Quality control on AI drafts | Whatever your own prompt produces is what sends | A critic reads every draft against its full brief and objects; drafts that keep failing are flagged for a human |
| Human review queue | None; the agent acts when you tell it to | A persistent queue where you approve, edit, retry or reject, and approving resumes the withheld action |
| API and AI agents | REST API, MCP server and an agent chat on every plan including the free one, with one key and one bill across all 42 providers | MCP server with over 300 tools; an AI agent can operate the entire platform, including the review queue and the inbox |
| Pricing model | Free with 300 credits, then $99, $199 or $499 a month for 7,000, 15,000 or 40,000 credits; 10% off annually, credits roll over three months, implementation quoted separately | $299/mo per client workspace ($249 annual), 25,000 credits included; LinkedIn accounts and team members are unlimited |
Where ColdIQ is genuinely strong
The marketplace is the real product, and it is well built. 42 providers behind one key means one bill, one auth flow and no minimum commitment per vendor, and swapping Findymail for Prospeo is a parameter rather than a migration. The credit rule is unusually fair: charged per identified person or company, never for setup or reads, so a lookup that finds nothing costs nothing. Unused credits roll over for three months. The free tier hands you 300 credits without a card.
The benchmark leaderboard is the part we would pay for. 19 mobile finders were run against the same 53 sales contacts, 28 in the EU and 25 in the US, across 15 companies and 6 verticals, scored on accuracy, coverage, price and speed, with providers inside the margin of error called statistical ties instead of ranked. That is more methodological honesty than most vendors apply to their own numbers, and no one else in this comparison set publishes anything like it.
Endpoints are not an engine
ColdIQ can send a LinkedIn invitation today: Unipile's 60 endpoints are in the marketplace and they cover invitations, messages and chats. What is missing is everything around the call. Nothing tracks that this account already sent 43 invitations today, that LinkedIn's practical ceiling is about 100 a week, that this one came back rate limited an hour ago, or that the person you are about to message replied to a different campaign yesterday. That state is what an outreach system mostly is, and with a marketplace you own all of it: the scheduler, the retries, the dedup, the record of who was contacted when.
CampaignStack is the other half. A cookie becomes an encrypted browser profile that keeps working while the laptop is closed. Each action type carries its own daily budget and a warm-up curve that only rises with use. Connection requests hold a rolling weekly cap. Three rate limits in a day pause that family of actions for 24 hours without touching the replies. None of that is exotic, but all of it has to exist before the first send, and none of it comes out of a data endpoint.
What it costs to get running
The two prices do not compare, because the units are not the same thing. ColdIQ credits buy identified records: $99 a month for 7,000, $199 for 15,000, $499 for 40,000. That works out to about 1.4 cents a record on Starter and 1.2 cents on Scale. CampaignStack's $299 per client workspace ($249 annual) buys 25,000 credits of delivery, where the units are connection requests, sends, profile scrapes and AI drafts. One prices what you learn, the other prices what you do. An agency running both pays both, and that is a sensible stack, not a duplicated one.
There is a third line on the bill. ColdIQ's own answer to who assembles the system is its implementation service: 90 days, first play live inside two weeks, three plays by day 45, your team running it alone by day 90, on the condition that you name one operator on day one and reserve four to six hours a week for them. The price is scoped per engagement and quoted after a call. That engagement, plus those weekly hours, is the honest cost of building it yourself, and it belongs next to the subscription before anyone decides which route is cheaper for a shop running eight clients.
CampaignStack vs ColdIQ: common questions
Is ColdIQ a competitor to CampaignStack or something I can use alongside it?
Mostly alongside. ColdIQ sells data: 42 providers and more than 700 endpoints behind one API key and one credit balance. CampaignStack sells delivery: LinkedIn and email execution, account safety budgets, ICP scoring, reviewed AI drafts and a shared inbox. They only compete on the question of who builds the system, because ColdIQ's pitch is that you assemble your revenue engine inside Claude Code from its endpoints, and ours is that the engine already exists and your agent drives it through an MCP server with over 300 tools.
Can ColdIQ send LinkedIn connection requests and messages?
Through a resold provider, yes. Unipile is in the marketplace with 60 endpoints covering LinkedIn, WhatsApp, Gmail and Outlook, including sending messages and handling invitations, and Instantly and Lemlist are there for email with 147 and 38 endpoints. What ColdIQ does not document is anything above the call: no daily caps per account, no warm-up curve, no weekly invitation ceiling, no pause when a rate limit comes back, no inbox for the replies. You write that yourself, or you accept the risk on your client's account.
Which one is cheaper?
They bill in different units, so the honest answer is that it depends what you are buying. ColdIQ is free for 300 credits, then $99, $199 or $499 a month for 7,000, 15,000 or 40,000 credits, charged per identified person or company, with 10% off annual billing and unused credits rolling over for three months. CampaignStack is $299 per client workspace ($249 annual) with 25,000 credits of delivery included and no per-seat or per-LinkedIn-account charge. Neither number includes the engineering time to connect them, which is why ColdIQ also sells a 90-day implementation engagement.
Do I still need a data marketplace if I run CampaignStack?
For phone numbers and personal emails at volume, probably yes, and ColdIQ is a good way to buy them. CampaignStack reads LinkedIn profiles and companies itself and tracks funding, hiring, headcount and news without a data vendor, and it routes contact enrichment to Apollo or Instantly when you connect either one. What it does not run is a waterfall across nine email finders. If that is your bottleneck, the two products stack cleanly.
Can I migrate from ColdIQ to CampaignStack?
There is not much to migrate, which cuts both ways. ColdIQ holds an API key and a credit balance rather than your campaigns, so nothing is locked in, but nothing transfers either: any scheduling, state or reply handling you wrote around its endpoints is yours and stays yours. Export the leads you have built to CSV and import them, connect each LinkedIn account with a session cookie in about two minutes, and rebuild the sequence as a workflow. Keep the ColdIQ key for enrichment if you use it.
