Kaspr vs Apollo 2026: B2B Contact Data for Cold Email
Kaspr extracts verified contact data from LinkedIn profiles in real time, with strong European coverage. Apollo is a bulk contact database for filtering and exporting at scale. They fit different prospecting workflows.
Two Different Ways to Build a Prospect List
Kaspr and Apollo both get you email addresses and phone numbers for B2B prospects. The path each tool takes to that data is completely different, and so is the cold email workflow each one fits. Kaspr extracts data from LinkedIn profiles as you browse them, producing real-time accuracy with strong European coverage. Apollo is a bulk database with 275 million-plus contacts you can filter and export in large batches. Picking the right tool for your ICP and workflow prevents wasted budget and produces more sendable emails per list.
What Kaspr Does
Kaspr (kaspr.io) is a Chrome extension that sits on top of LinkedIn. Open a LinkedIn profile and Kaspr shows you that person's verified email address and direct phone number in a sidebar panel. It also works on LinkedIn search results pages, letting you bulk-reveal contact data for everyone visible in your search results. Because Kaspr pulls data from LinkedIn in real time, the contact information reflects the prospect's current employer, not a stale database record from six months ago.
This real-time data pull is where Kaspr earns its strongest advantage. People change jobs frequently in B2B. A database captured six months ago may have 10 to 20% of records showing outdated companies for fast-moving roles like SDRs, account executives, and marketing managers. Kaspr's LinkedIn-native approach catches current-state data that Apollo's periodic refresh misses.
European data coverage is Kaspr's other major edge. Email find rates for UK, France, Germany, Netherlands, and Nordics run 75 to 85% with Kaspr, compared to 55 to 70% in the same geographies with Apollo. For a cold email operation targeting EU markets, that gap means materially more emails per prospect list.
Kaspr pricing: Free plan with 5 phone credits and 5 email credits per month. Starter at $49/month for 1,200 email credits and 60 phone credits. Business at $79/month for 12,000 email credits and 120 phone credits.
What Apollo Does
Apollo.io holds 275 million-plus professional records you can filter by job title, industry, company size, technology stack, funding status, geography, and revenue range. You build a target list using those filters and export bulk contact data ready for verification and sending. In a few minutes, you can filter to 2,000 Director-level SaaS contacts at companies with 50 to 500 employees using HubSpot who raised Series A or B in the last 18 months. Apollo returns emails and phone numbers for the majority of those records.
The bulk workflow is where Apollo has no real competitor at its price point. Kaspr's profile-by-profile workflow is efficient for targeted account research, but it cannot match Apollo's speed when you need a 2,000-contact export in minutes. For US-centric outbound at scale, Apollo's filter depth and database size are the standard choice.
Apollo also includes buyer intent signals, a built-in email sending tool, and an AI research assistant. Most cold email operators use Apollo only for data and route it through Instantly or Smartlead for sending, where deliverability controls are significantly stronger.
Pricing: Free plan with 10 email credits per month. Basic at $49/user/month for 1,200 email credits. Professional at $99/user/month for 24,000 credits and advanced filters. Organization at $149/user/month for enterprise features.

When Kaspr Is the Right Choice
Kaspr is the right tool when your ICP is primarily in European markets. UK, France, Germany, Benelux, and Nordics are where Kaspr consistently outperforms Apollo on find rate and data freshness. It also fits targeted, account-based prospecting where you are researching 200 specific companies and want accurate contact data for 3 to 5 people at each account. For teams running account-based cold email in European markets, Kaspr at $49 to $79/month delivers the data quality that matters without the per-seat cost of larger enterprise data tools.
When Apollo Is the Right Choice
Apollo is the right choice for US-centric outbound and any workflow where you need to build large contact exports quickly. The filter depth, technographic data, and bulk export capability have no equivalent in Kaspr at this price point. If your ICP is US mid-market SaaS and you want 1,000 to 5,000 contacts exported weekly for campaigns in Instantly or Smartlead, Apollo handles this workflow efficiently. Pair it with ZeroBounce verification before every send and pre-warmed Puzzle Inbox inboxes for the infrastructure layer.
Running Both
High-performing cold email operations often run both tools: Apollo for US bulk campaigns and Kaspr for European named account research. The combined cost runs $130 to $150 per month, appropriate for any team sending 200-plus cold emails per day to diversified geographies. Verify all lists through ZeroBounce before uploading to your sending platform regardless of which tool built the list.
Kaspr vs Apollo: what cold email operators actually need to compare
Most "Kaspr vs Apollo" 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: Kaspr vs Apollo
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 Kaspr and Apollo, 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 Kaspr and Apollo 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 Kaspr or Apollo 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 Kaspr and Apollo 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 Kaspr or Apollo 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. See the pricing page, Google Workspace plans, or Outlook 365 plans for current per-inbox numbers. Reviews follow our published editorial methodology.
Kaspr vs Apollo FAQ
Which is cheaper, Kaspr or Apollo?
The cheaper of Kaspr and Apollo 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, Kaspr or Apollo?
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 Kaspr and Apollo 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 Kaspr and Apollo 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.
