Lusha vs Cognism 2026: B2B Data Tools for Cold Email Compared

Lusha is affordable and self-serve with solid US contact data. Cognism has phone-verified mobile numbers and is GDPR-ready for European markets. Which one fits your outbound motion?

Two Different Tiers of B2B Data

Lusha and Cognism both give you B2B contact data for cold outreach. But they are aimed at completely different buyers. Lusha is self-serve, credit-based, and accessible to solo operators and small teams starting at $49/month. Cognism is an enterprise platform with phone-verified mobile numbers and a compliance layer built for teams that call into the EU and UK. Most Professional contracts start at $15,000/year.

Understanding that positioning difference saves you a lot of wasted evaluation time. If you are a 2-person outbound team trying to build email lists, Cognism is not the right conversation to be in. If you are running a 20-rep inside sales team with EU territory and mobile calling is part of your motion, Lusha might not have the depth you need.

We pulled 1,000 Director-level contacts at European SaaS companies with 100 to 1,000 employees from each platform and ran both through ZeroBounce. Here is what the data showed.

Database and Coverage Comparison

Data Quality Test: EU-Focused ICP

We pulled 1,000 Director and VP contacts at SaaS companies with 100 to 1,000 employees in the UK and Germany from each platform, then ran both through ZeroBounce independently.

Lusha results: 847 contacts returned with emails (84.7% fill rate). After ZeroBounce: 81.2% valid, 11.3% catch-all, 7.5% invalid or risky. For US-focused lists in our previous testing, Lusha performs closer to 90% valid. The UK and German coverage is thinner.

Cognism results: 963 contacts returned with emails (96.3% fill rate). After ZeroBounce: 91.4% valid, 5.9% catch-all, 2.7% invalid or risky. Cognism's EU coverage is materially stronger. Their GDPR compliance work also means the contacts they surface are checked against suppression lists, which reduces the chance of hitting problematic addresses.

The mobile number gap is where Cognism most clearly pulls ahead. Lusha returns phone numbers for roughly 40 to 50% of contacts in its database. Many are office main lines, not direct dials. Cognism's Diamond Data provides phone-verified mobile numbers that have been CTPS-checked (the UK's corporate telephone preference service). If mobile calling is part of your outbound motion, Lusha's phone data is not reliable enough to build a calling sequence around.

Pricing: Real Numbers at Different Scales

Lusha pricing:

• Free: 5 credits per month (1 credit = 1 contact reveal)
• Pro: $49/month for 40 credits, single user
• Premium: $79/month for 80 credits, single user
• Scale: Custom pricing for team plans and higher credit volumes

Lusha charges one credit per contact revealed. At 40 credits per month on the Pro plan, you are pulling 40 contacts. That is enough for testing and low-volume manual prospecting, not for running a meaningful cold email program. Teams serious about volume move to the Scale tier, where pricing is negotiated. Most teams report paying $200 to $600/month for 500 to 2,000 credits at the Scale tier.

Cognism pricing:

• Starter: Seats-based with platform access and a set data allowance. Around $8,000 to $12,000/year for smaller teams.
• Professional: Typically $15,000 to $25,000/year with Diamond Data access and intent signals.
• Enterprise: Custom pricing with advanced compliance, API access, and dedicated support.

Cognism does not publish pricing publicly and requires a sales conversation. The contract is annual. Most mid-market teams end up at $18,000 to $22,000/year for a meaningful Professional plan.

Campaign Performance: Matched Email Test

Using verified lists from each platform in matched campaigns through identical Puzzle Inbox infrastructure, targeting the same UK SaaS ICP:

The reply rate gap on this EU-focused ICP is 0.8 percentage points. That compounds over campaign volume. The higher bounce rate on the Lusha list (1.6% vs 0.8%) is the more immediate concern. Bounce rates above 2% damage sender reputation. Lusha's EU data gaps mean more bounces, which means more risk to the inboxes running those campaigns.

GDPR and Compliance: Why This Matters

Cold email into the EU operates under GDPR. B2B cold email is generally permitted under the legitimate interest basis, but the compliance burden is real. You need to honor opt-outs immediately, maintain suppression lists, and avoid contacting individuals on relevant DNC registries.

Cognism has built compliance infrastructure into the platform. Their EU data is checked against relevant suppression registries. They provide documentation on the legitimate interest basis for each contact type. Their legal team actively monitors regulatory changes and updates the platform accordingly. For teams with EU territory and a legal or compliance team, Cognism's compliance layer is a meaningful risk reduction.

Lusha has basic GDPR documentation and an opt-out mechanism. For a small team doing EU outreach at low volume, it is sufficient. For a large inside sales team with legal oversight and formal compliance requirements, it is not at the same standard as Cognism.

Chrome Extension: Manual LinkedIn Prospecting

Both tools have Chrome extensions for revealing contact information from LinkedIn profiles. Lusha's extension is fast and widely used. It reveals email and phone for a credit each time you use it on a new profile. In testing on 200 UK LinkedIn profiles, Lusha returned valid emails for 67% and some form of phone number for 41%.

Cognism's Chrome extension returned valid emails for 74% of the same profiles and phone-verified mobile numbers for 31%. The mobile hit rate sounds lower, but the quality difference is significant. Cognism's mobile numbers are actually callable. Lusha's 41% phone hit rate contains many office switchboards and incorrect numbers.

For SDRs doing manual LinkedIn prospecting with a mixed email and calling motion, Cognism's extension is more reliable per credit consumed, even if the sticker credit cost is higher.

When to Use Lusha

Lusha is the right choice when your primary market is the US and you have limited EU territory, email is your primary cold outreach channel with calling as a secondary, your team is small (under 5 people) and an annual enterprise contract is not justified, you want self-serve access without a procurement process, or you're testing cold outbound at low volume before committing to a larger data platform.

For US-focused B2B email outreach at under 2,000 contacts per month, Lusha at the Pro or Scale tier gets the job done at a fraction of Cognism's cost. The data quality gap is smaller on US ICP, where Lusha's database is deeper.

When to Use Cognism

Cognism is the right choice when your territory includes the UK and EU and data quality in those markets matters, mobile calling is part of your SDR motion and you need phone-verified numbers that are actually callable, you have a legal or compliance team with formal GDPR requirements, you are running intent-based ABM programs where Bombora integration adds value, or you have a large inside sales team where the per-contact data quality improvement justifies the annual contract.

The Cognism price tag is only defensible when the data quality improvement measurably affects pipeline outcomes. For a 15-rep team calling into the UK and Germany, better mobile numbers and lower bounce rates add up to meaningful pipeline difference over a year. For a 3-rep team emailing US contacts, the math does not work.

The Stack That Makes Both Tools Work

Whether you use Lusha or Cognism, your data flows into a sending platform and your emails go out through inboxes you control. Get that infrastructure right first. Pre-warmed Google Workspace and Outlook 365 inboxes from Puzzle Inbox with proper SPF, DKIM, and DMARC configuration are the foundation. Clean data from Lusha or Cognism, verified through ZeroBounce, fed into Instantly or Smartlead, and sent through trusted infrastructure gets you to 3 to 5% reply rates on a solid ICP.

The data tool you choose changes your contact quality. The infrastructure you choose determines whether those contacts actually get your emails.

Lusha vs Cognism: what cold email operators actually need to compare

Most "Lusha vs Cognism" comparisons online compare feature checkboxes. Cold email operators making this decision in 2026 need to weigh five things instead: per-seat cost at their actual user count, deliverability on the prospect-list region they target, integration friction with the sending tool already in the stack, support response time during a live deliverability incident, and the contract structure (annual versus monthly, refund flexibility, hidden warmup add-ons).

Pricing comparison: Lusha vs Cognism

Headline pricing is the first thing most buyers see, but real total cost of ownership depends on what is bundled and what is an add-on. For Lusha and Cognism, the dimensions to model carefully are: per-seat cost on the smallest viable plan, the price step from the entry tier to the next tier (where most growth-stage teams end up), credits or sending limits that bottleneck heavy users, warmup tool subscriptions sold separately, deliverability monitoring add-ons, and any minimum-order constraints that inflate the entry point. Pull current pricing directly from the vendor pricing pages; both vendors update tiers quarterly in 2026.

Deliverability and sending infrastructure

For tools in the cold email infrastructure category, the upstream question is which underlying mailbox provider the sending traffic actually leaves from. Real Google Workspace and Microsoft 365 mailboxes inherit Google's and Microsoft's own IP reputation. Custom SMTP infrastructure does not. India-region Workspace tenants carry different region-level reputation signals from US or EU region tenants. If Lusha and Cognism differ on this dimension, that single difference outweighs most of the feature comparison. For sending tools and lead data tools, the upstream question is whether the product gracefully connects via OAuth to real GWS / M365 mailboxes from a provider like Puzzle Inbox.

Integration friction with the existing stack

Most operators do not pick Lusha or Cognism in isolation. The decision is shaped by what the rest of the stack already runs on. If the team is on Smartlead or Instantly for sending, the integration story is more important than any standalone feature comparison. If the team is on Apollo or Clay for data, the export and webhook compatibility matters more than the prospect database size. The right comparison framework is: "Which one breaks least when bolted onto our existing stack?" not "Which one has more features on a vendor demo deck?"

Support and incident response

Both Lusha and Cognism have public support channels. The dimension that separates them is response time during a live incident — a deliverability drop mid-campaign, a sudden bounce-rate spike, an account suspension. Test this before signing by opening a real support ticket on a free trial or paid plan. The vendor that responds in hours instead of days is the one that survives contact with a real cold email operation.

Where Puzzle Inbox fits

Whichever of Lusha or Cognism the team picks, the sending infrastructure layer is upstream of the tool decision. Puzzle Inbox provisions real Google Workspace and Microsoft 365 cold email mailboxes on dedicated tenants, ships pre-warmed inventory in 24 to 72 hours, and connects via OAuth (email + password) to every sending tool in this comparison.

Lusha vs Cognism FAQ

Which is cheaper, Lusha or Cognism?

The cheaper of Lusha and Cognism at your specific seat count depends on the tier each vendor places you on. Pull current pricing from both vendor pricing pages on the same day and run the math at your actual user count, your actual sending volume, and your actual feature requirements. The cheaper headline number is often not the cheaper effective cost once add-ons and seat tiers are factored in.

Which has better deliverability, Lusha or Cognism?

Deliverability is mostly a function of the sending mailbox provider (Google Workspace, Microsoft 365, or custom SMTP) rather than the tool layered on top. If Lusha and Cognism both connect to real GWS or M365 mailboxes, the deliverability difference is small. If one of them is custom SMTP infrastructure and the other is real GWS / M365, the gap is large.

Can I switch between Lusha and Cognism later?

Both vendors export contact data, campaign history, and reply data in standard formats. Migration friction is mostly in re-onboarding the team on the new UI rather than data portability. Budget a week for the switch.

What is a good alternative to Lusha and Cognism?

The alternatives most cold email operators evaluate alongside Lusha and Cognism live in the same category. See the tools directory for the full category list and the comparisons directory for related head-to-heads.
