7 Best FullEnrich Alternatives for B2B Enrichment in 2026
FullEnrich's 4.8/5 on G2 across 172 reviews is earned - the waterfall approach works, and the "only pay for found data" model is fair. But the credit math gets painful fast, and the Chrome extension shutdown left a real gap in daily workflows. If you're shopping for FullEnrich alternatives, here's what actually holds up after we tested each one.
Our Picks (TL;DR)
- Best for email accuracy + self-serve: Prospeo
- Best all-in-one platform: Apollo.io
- Best free tier for emails: Kaspr
Why Teams Switch from FullEnrich
The credit structure is the core issue. Work emails cost 1 credit, personal emails cost 3, and phone numbers cost 10. A 500-credit plan only gets you 50 phone lookups - that's it. For teams doing heavy phone prospecting, the math breaks down before the quarter's halfway done. On Reddit, buyers shopping for alternatives consistently describe FullEnrich pricing as "a bit high."
User reviews tell the rest of the story. Incorrect phone numbers top the complaints with 11 mentions, followed by "expensive" at 8, integration issues at 7, and slow loading at 5. For a tool whose entire value proposition is data quality, that incorrect-numbers count stings. The Chrome extension discontinuation in June 2024 compounds the friction - you're now copy-pasting profile URLs into the web app instead of enriching contacts while you browse.
One thing FullEnrich does well: unlimited users on all plans with shared credits. That's genuinely useful for larger teams. But the tooling around the data hasn't kept pace.
FullEnrich charges 10 credits per phone number and killed its Chrome extension. Prospeo gives you 125M+ verified mobiles, 98% email accuracy, and a Chrome extension used by 40K+ people - all refreshed every 7 days. Start free with 75 emails and 100 extension credits.
Stop overpaying for enrichment data that bounces.

Best FullEnrich Alternatives Compared
Prospeo
Prospeo's database covers 300M+ professional profiles, 143M+ verified emails, and 125M+ verified mobile numbers. It runs proprietary email-finding infrastructure rather than aggregating the same third-party providers most waterfall tools chain together - that's how it hits 98% email accuracy with a 7-day data refresh cycle, compared to the 6-week industry average.
The Chrome extension, used by 40K+ people, works across company websites, professional profiles, and CRMs. Intent data covers 15,000 Bombora topics for layering buying signals on firmographic filters. Native integrations push directly into Salesforce, HubSpot, Smartlead, Instantly, Lemlist, and Clay.
Real-world proof: Snyk's team of 50 AEs went from a 35-40% bounce rate to under 5% after switching, with AE-sourced pipeline up 180%. The free tier gives you 75 emails and 100 Chrome extension credits monthly - enough to validate the accuracy yourself before committing a dollar. Pair with Instantly or Lemlist for outbound execution and you've got a complete prospecting stack without the enterprise price tag.
Apollo.io
Use this if you want enrichment, sequences, and a lightweight CRM in a single platform.
Apollo's database covers 275M+ contacts, and the free plan is genuinely usable - limited credits but full access to search and the sequence builder. Paid plans run $49-$119/user/month on annual billing. For a team that needs to move fast without buying four separate tools, Apollo makes the most sense as a starting point.
The tradeoff is data quality. In our testing, Apollo's email accuracy runs noticeably below dedicated enrichment platforms, and mobile number coverage for director+ roles outside North America gets thin. Credit limits on phone numbers and exports can also surprise you mid-quarter. Apollo's strength is breadth, not precision - skip it if email deliverability is your top priority.
Kaspr
Ranked the #1 FullEnrich alternative on G2, Kaspr is built for teams that prospect heavily on professional networks and want unlimited B2B emails without credit anxiety. The free plan gives you 5 phone and 5 direct email credits monthly. Starter runs EUR 59/user/month with 100 phone credits and unlimited B2B emails. Business at EUR 99/user/month bumps phone credits to 200 and adds API access.
The caveat: your account needs a minimum of 20 connections to function, and "unlimited B2B emails" doesn't extend to phone numbers or direct emails - those are still credit-gated. Skip Kaspr if you need API-first enrichment at high volume or want a workflow that doesn't depend on browser-based prospecting.
Lusha
Here's the thing about Lusha: if you're leaving FullEnrich because of credit math, switching here doesn't fix that problem. The credit structure is identical - 1 credit per email, 10 per phone number. The free plan includes 70 credits monthly, and paid plans start around $22.45/user/month with rollover up to 2x your plan limit.
What you do get is a working Chrome extension and a cleaner UI. That's a real upgrade from FullEnrich's current copy-paste workflow. But the economics are the same, so don't expect your per-lead cost to drop.
Clay
Clay isn't a direct enrichment replacement - it's a workflow orchestration platform that happens to plug into enrichment providers. If you just need a database to pull emails from, this isn't your tool.
New pricing announced in March 2026 starts at $185/month for Launch with 2,500 data credits and 15,000 actions, or $495/month for Growth with 6,000 data credits. CRM integrations now live on the Growth tier. Best for teams building multi-step enrichment and outreach workflows where the automation itself is the value, not one-off lookups.
Cognism
Enterprise-grade enrichment with a strong EMEA and GDPR compliance story. Verified mobile numbers are the headline feature. Pricing is quote-based - expect roughly $22,500-$37,500/year for a 5-person team depending on the package. Best for teams with EMEA-heavy ICPs and budget to match. Skip this if your annual enrichment budget is under $20K or your ICP is North America-only.
Pipe0
API-first waterfall enrichment built for engineering teams. You configure which providers run in your waterfall and in what order - up to 15,000 inputs per request versus FullEnrich's 100. Plans run $49-$999/month, with per-email costs around 1.5-3 cents. Best for custom enrichment pipelines with granular provider control. Skip this if you want a GUI-first experience or don't have engineering resources to maintain the integration.
Which One Should You Pick?
Let's be honest: most teams overthink the enrichment stack. You need one data tool and one outbound platform. That's it.
We've tested each tool above, and every one beats FullEnrich on at least one axis. If email accuracy and data freshness are the priority, Prospeo is the clear pick - 98% accuracy with a 7-day refresh at roughly a penny per email is hard to beat, and the free tier lets you prove it before spending anything. If you want enrichment and outbound in one platform, Apollo gets you moving fastest. For unlimited B2B emails on a budget, Kaspr's paid plans deliver. EMEA compliance? Cognism. Workflow automation? Clay. API-scale custom pipelines? Pipe0.
Run a 500-lead pilot with your top pick for 30 days before committing annually. The data will tell you more than any comparison article - including this one.
Snyk's 50 AEs dropped their bounce rate from 35-40% to under 5% and grew AE-sourced pipeline 180% after switching. Prospeo's proprietary email infrastructure doesn't chain the same third-party providers as waterfall tools - that's why accuracy hits 98% at $0.01 per email.
Replace the waterfall with data that actually connects.
FAQ
What Is Waterfall Enrichment?
Waterfall enrichment sequentially queries multiple data providers until a match is found, improving coverage over any single source. FullEnrich uses this approach and reports an average ~80% find rate. One vendor benchmark showed waterfall methods hitting 98% email found rates versus 62% for single-source tools.
Does FullEnrich Have a Chrome Extension?
FullEnrich discontinued its Chrome extension in June 2024, forcing users to copy-paste profile URLs into the web app. Alternatives with working Chrome extensions include Prospeo (40K+ users), Kaspr, Lusha, and Apollo.io.
How Much Does FullEnrich Cost per Phone Number?
Each phone number costs 10 credits. On a 500-credit plan, that's only 50 phone lookups. Personal emails cost 3 credits each, and work emails cost 1 credit. Credits only deduct on successful finds.
