CampaignStack vs Lusha: the data is the product
Lusha's contact data is the reason people pay for it: 290M contacts and 26M companies by its own count, verified emails and direct dials revealed at a click, with audited GDPR and CCPA compliance and a free tier to try it on. It also bundles Engage, a free email sequencer, and a 24-tool MCP server. What Lusha never does is send anything on LinkedIn: the extension reveals contact details while you browse, and that is where its LinkedIn story ends. This page walks that line.
You need verified emails and phone numbers, and compliance sign-off matters to whoever approves the purchase. Lusha publishes its accuracy claims (98% on emails, 86% on phones), holds audited GDPR and CCPA validations plus ISO 31700 and SOC 2 Type 2, and the free plan gives you 40 reveals a month to judge the data yourself. Engage adds email sequences at no extra charge on every plan.
LinkedIn has to actually run, unattended, on accounts that belong to your clients. Each account gets its own cloud browser and residential proxy with per-action budgets, drafts face a critic before a human ever sees them, and doubtful ones wait in a review queue. Lusha has no LinkedIn delivery to hand this to; here the delivery is the product.
A data platform and a delivery platform
Capabilities as documented by each vendor, checked August 2026. Lusha wins the data rows outright and the table says so; the outreach rows are where the two stop being comparable.
| Capability | Lusha | CampaignStack |
|---|---|---|
| B2B contact database | 290M contacts and 26M companies by its own count; an email reveal costs 1 credit, a phone number 10 | None. Leads come from LinkedIn sourcing, imports, or a connected provider such as Apollo |
| Browser extension prospecting | Reveals verified contacts on LinkedIn, Sales Navigator, Recruiter and company sites, up to 25 profiles at once from a search page on paid plans | Not offered. Sourcing runs server-side from searches, post engagements, groups and imports |
| LinkedIn outreach | Nothing sends. The extension reads LinkedIn pages to reveal contact details; invites and messages are not part of the product | Connection requests, messages, InMail and engagement through a persistent cloud browser per account |
| Native email sending | Engage sends sequences from a connected Gmail or Outlook account, up to 1,000 emails a day, included on every plan | Gmail sending with its own daily budgets and warm-up, inside the same workflow graph |
| LinkedIn account safety | Nothing to govern, since nothing runs on LinkedIn; the extension reads pages in your own browser | Per-action-type daily budgets, usage-based warm-up, weekly caps, business-hours pacing, automatic risk pause |
| AI-drafted messages | The AI Email Assistant generates a sequence from your goal and the prospect's data, with tone control and personalization tags | Openers, follow-ups and inbound replies drafted against your playbook and the lead's live context |
| Quality control on AI drafts | You edit the generated sequence yourself before launch; no documented critique or scoring pass on a draft | A critic reads every draft against its full brief and objects; drafts that keep failing are flagged for a human |
| Human review queue | Sequences send on schedule once live; no queue holds individual sends for sign-off | A persistent, skippable queue where you approve, edit, retry or reject, and approving resumes the withheld action |
| Buying signals | 24 real-time signals by its own count, from job changes and funding to intent topics and website visitors, delivered as alerts, API and MCP | Job changes, title changes, post engagement, funding and headcount changes feed campaign scoring |
| ICP scoring | Target Profiles in its ICP Hub produce a fit score, and AI recommendations rank accounts and contacts against it | Every lead is scored against every campaign's ICP; the score decides campaign membership |
| API and AI agents | Public API plus a hosted MCP server with 24 tools, one-click OAuth in Claude and ChatGPT, API-key access from other clients | MCP server with over 300 tools; an AI agent can operate the entire platform |
| Pricing model | Free plan with 40 monthly credits; $49.90, $69.90 or $399.90 per month for 400, 600 or 3,400 shared credits, less on annual billing; teams over 5 users go through sales | $299/mo per client workspace ($249 annual), 25,000 credits included; LinkedIn accounts and team members are unlimited |
Where Lusha is genuinely strong
Lusha's pitch is trust in the data, and it backs that up in ways most of this category does not. It publishes its own accuracy claims, 98% on emails and 86% on phone numbers, and it carries audits few data vendors bother with: GDPR validated by ePrivacyseal, CCPA by TrustArc, ISO 31700 and SOC 2 Type 2. If your buyer's legal team asks where the phone numbers came from, Lusha has the better answer on paper than almost anyone.
The bundle is generous too. Engage, its email sequencer with an AI assistant, costs nothing extra on any plan including free. And its agent story arrived early: a hosted MCP server with 24 tools across search, enrichment, signals and recommendations, with one-click OAuth from Claude and ChatGPT. For a data company, that is a serious surface.
Lusha reads LinkedIn. It never sends on it
The extension is Lusha's whole LinkedIn presence, and it is a reader. It sits on a profile, a search page or Sales Navigator and reveals the person's verified email and phone number. It does not send an invite, a message or an InMail, and nothing in the product queues one. When Lusha's materials talk about outreach, they mean Engage, which is email.
Because nothing automated touches LinkedIn, Lusha needs no session handling and no safety system, and it has neither. That is coherent for what it sells. It also means the LinkedIn half of your outbound is entirely yours to execute: every invite, follow-up and reply is a person with a browser tab, at whatever pace they can sustain.
CampaignStack runs each account in its own encrypted browser profile on our server behind a static residential proxy, with per-action-type 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. The messages go out while nobody is watching, which is the only version of this that scales past one client.
The credits ration different things
Both products meter usage in credits, and the word means something different on each side. A Lusha credit buys one contact reveal: 1 credit for a verified email, 10 for a phone number, from a monthly pool of 400, 600 or 3,400 depending on plan. A CampaignStack credit buys an action: a profile enriched, a message drafted and sent, a post engaged, from a pool of 25,000 per workspace. Comparing the two numbers tells you nothing; each rations the thing its platform actually does.
The two are not wired together today. Apollo and Instantly connect as enrichment providers inside CampaignStack; Lusha does not, so the practical bridge is an export. A Lusha list lands here as a CSV import, private to the workspace it enters, and the leads deduplicate on LinkedIn identity once enrichment runs.
So the honest split: if the job is knowing who to call and having a number that connects, Lusha is built for it and this platform is not. If the job is a hundred LinkedIn conversations a week that your team did not type, that is what CampaignStack does and Lusha does not enter the building.
CampaignStack vs Lusha: common questions
Does Lusha automate LinkedIn?
No. Lusha's extension reveals verified emails and phone numbers while you browse LinkedIn, Sales Navigator or Recruiter; it does not send connection requests, messages or InMail, and no part of the product automates LinkedIn actions. Lusha's outreach product, Engage, sends email sequences from a connected Gmail or Outlook account. CampaignStack runs LinkedIn actions server-side in a persistent browser profile per account, with per-action daily budgets.
Is Lusha cheaper than CampaignStack?
For contact data, yes; the products price different things. Lusha's paid plans run $49.90, $69.90 or $399.90 per month for 400, 600 or 3,400 credits, where a credit is a contact reveal (1 for an email, 10 for a phone number), and a free plan gives 40 credits monthly. CampaignStack costs $299 per month per client workspace ($249 on annual billing) with 25,000 action credits and unlimited LinkedIn accounts and team members. If you only need verified contact details, Lusha is the cheaper and better fit.
Lusha has an MCP server too. What is actually different?
Scope. Lusha's MCP server exposes 24 tools over its data: contact and company search, enrichment, lookalikes, signals and recommendations, with one-click OAuth from Claude and ChatGPT. It is a data faucet for agents, and a good one. CampaignStack's MCP server exposes over 300 tools spanning sourcing, campaigns, drafting, the inbox, the review queue and admin, because the agent is expected to operate the delivery itself rather than fetch records.
Can I use Lusha and CampaignStack together?
Yes, through exports rather than a native integration. Lusha is not a connected enrichment provider in CampaignStack today (Apollo and Instantly are), so the working pattern is: build and reveal your list in Lusha, export it, and import the CSV into a CampaignStack workspace, where leads deduplicate on LinkedIn identity. Lusha keeps the reveal work and the phone numbers; CampaignStack takes the LinkedIn delivery, the drafting and the review queue.
Can I migrate from Lusha to CampaignStack?
Only the outreach half, and most teams should not cancel the data side. Engage sequences rebuild as CampaignStack workflows, your lists come over as CSV imports, and LinkedIn accounts onboard with a session cookie in about two minutes each. What does not transfer is the database: cancel Lusha and the reveals stop, so if verified phone numbers matter to your motion, keep a Lusha plan for the data and let CampaignStack own the delivery.
