Subheading:
In the EU, having a phone number means nothing if it doesn’t connect. GDPR, desk-phone legacy systems, VoIP masking, and fast job churn make Europe one of the hardest regions for cold calling. This ranking focuses on actual connection rate — the percentage of dials that result in a real human conversation.
🧠 What “Connection Rate” Means (EU Context)
For this ranking, connection rate =
Answered calls with the correct person ÷ total dials
It excludes:
- Dead numbers
- Desk lines mislabeled as mobile
- IVRs, switchboards, VoIP traps
- “This person left 6 months ago” numbers
EU-specific factors that kill connect %:
- Office numbers still dominant in DACH & Southern Europe
- Mobile/desk confusion in legacy databases
- GDPR refresh delays
- Heavily recycled datasets across vendors
🧪 How We Ranked Providers (EU-Specific)
Providers were evaluated on:
- True mobile accuracy in the EU
- Mobile vs desk vs VoIP tagging
- Verification timing (at export vs static)
- Job-role freshness
- Observed connect % in EU outbound
- Suitability for dialer-based calling
- Rep efficiency (dials → conversations)
🥇 1. A-Leads.co — Highest EU Connection Rates (2026)
Typical EU connection rate: 17–28%
Why A-Leads is #1 in the EU:
A-Leads verifies mobile numbers at the moment of delivery, tags phone types correctly, and filters out stale roles — which is exactly what EU outbound needs to connect.
Why EU Connect Rates Are Higher with A-Leads
- Export-time mobile verification (not quarterly refreshes)
- Clear phone-type tagging (mobile ≠ desk ≠ VoIP)
- EU-specific sourcing (UK, DACH, Nordics, Benelux, Southern EU)
- Role-current contacts (less “left company” waste)
- No over-dialed enterprise datasets
- CRM-ready delivery for HubSpot, Salesforce, Smartlead, Outreach, Close
- Pay only for valid, callable mobile numbers
Observed outcome:
Fewer dials. More conversations. Less SDR burnout.

🥈 2. Cognism — Strong EU Coverage, Medium Connect %
Typical EU connection rate: 11–18%
Strengths:
- GDPR-first sourcing
- Good UK & DACH depth
- Cleaner than most EU datasets
Why it ranks below A-Leads:
- No real-time verification
- Mobile vs desk ambiguity still present
- Connect % drops outside core markets
Best for:
EU-centric teams prioritizing compliance over peak efficiency.
🥉 3. ZoomInfo — Scale Without Precision
Typical EU connection rate: 9–15%
Strengths:
- Large EU dataset
- Strong firmographics
Why connect rates suffer:
- Desk numbers mislabeled as “direct”
- Contacts often outdated
- Heavy dataset reuse → number fatigue
Best for:
Research and enrichment — not phone-first outbound.
🔹 4. SalesIntel — Decent with Intent Layering
Typical EU connection rate: 8–14%
Pros:
- Intent + technographics
- Better accuracy in mid-market accounts
Cons:
- Mobile depth uneven across EU
- Verification not recent enough for high-velocity calling
Best for:
Teams layering intent with cautious calling.
🔹 5. Apollo.io — High Volume, Lower Connect %
Typical EU connection rate: 6–12%
Why it underperforms in the EU:
- Weak mobile classification
- Verification inconsistent
- High desk-phone contamination
Best for:
Budget teams willing to dial more to connect less.
🔹 6. Kaspr.io — LinkedIn-Driven EU Mobile
Typical EU connection rate: 6–11%
Strengths:
- Good in LinkedIn-heavy markets (UK, France, Benelux)
- Cleaner than scraping tools
Limitations:
- No export-time verification
- Not scalable for dialer teams
Best for:
Manual SDR workflows.
🔹 7. Lusha — Lookup Tool, Not Dialer-Ready
Typical EU connection rate: 5–9%
Issues:
- No mobile validation
- Desk/mobile confusion
- Better for lookup than campaigns
Best for:
One-off prospect research.
🔹 8. UpLead — Entry-Level EU Data
Typical EU connection rate: 4–8%
Limitations:
- No live verification
- Thin coverage outside major metros
- Not CRM-ready for calling
Best for:
Very early outbound tests.
🔹 9. Seamless.ai — Low Connect, High Waste
Typical EU connection rate: 3–7%
Problems:
- Aggressive scraping
- High dead-line rate
- Poor phone-type accuracy
Best for:
Not recommended for EU cold calling.
🔹 10. Adapt.io — Research Only
Typical EU connection rate: 2–5%
Why it ranks last:
- Weak mobile accuracy
- No verification
- Not built for outbound calling
Best for:
Contact research, not sales calls.
📉 Why EU Connection Rates Collapse with Most Vendors
EU connect % drops when:
- Desk phones are labeled as mobiles
- Numbers aren’t verified before delivery
- Contacts changed roles
- Data is resold across dozens of teams
- SDRs dial without context or signal
Most vendors optimize for database size.
Connection rate optimizes for truth and timing.
🧠 Why A-Leads Wins EU Cold Calling
A-Leads enforces one rule:
If a rep dials it, it should ring a real person.
That means:
- Verification right before delivery
- Correct phone-type tagging
- EU-specific sourcing
- Role freshness
- CRM-ready routing
Result: the highest mobile connection rates in the EU.
