Email Finder

Email Finder: Find Anyone's Verified Business Email.

ListPlus is an email finder built on a waterfall of 15+ providers. Enter a name and company, or a LinkedIn URL, and get a verified business email in under 2 seconds. Every result runs through SMTP verification before it reaches you. You pay only when an email is found — €0.02 per verified email.

The Problem

Why single-provider email finders miss half your prospects

Hunter.io, Snov.io, and Lusha are all built on single data sets. Coverage stops at 40-60% for any individual B2B contact. If you use only one, you miss half your prospects — and you still pay full price for the empty lookups.

Coverage Gap
40–60%
Coverage per provider

No single email database covers more than 60% of B2B contacts. Hunter, Apollo, Lusha, Cognism — each misses the other half. Using one means guessing which half you'll find.

Tool Sprawl
3–5
Tools a typical team juggles

RevOps teams end up with Hunter for domain search, Apollo for list building, Lusha for phone, ContactOut for LinkedIn, and a CSV cleaner for the mess. Every tool has its own credits, pricing and API key.

Deliverability
15–25%
Bounce rate on unverified emails

Even when the email exists, many finders return generic addresses (info@, contact@, team@) or outdated data. Without SMTP verification, one in four sends bounces — and Gmail/Outlook start throttling your domain.

Wasted Spend
€€€
Wasted spend on empty results

Most providers charge per lookup, not per hit. Run 1,000 searches at €0.05 each on Hunter and pay €50 whether you found 400 emails or zero. ListPlus charges only for verified hits.

The Bottom Line
You're paying three vendors to find half the emails — and burning your sender reputation on the bounces.

A real email finder needs every database behind it, every result verified before delivery.

The Solution

One email finder. 15+ sources. Pay only for verified results.

ListPlus cascades every lookup through a waterfall of email finders — FullEnrich, Prospeo, Hunter, Apollo, Lusha, Cognism, ContactOut, Snov — until a verified address is returned. Single API, single subscription, single credit system.

Waterfall
15+ email providers in one cascade

FullEnrich alone waterfalls through Apollo, Hunter, Lusha, Cognism, ContactOut, and LeadMagic. Add Prospeo (LinkedIn URL → verified email), Enrich.so, Serper, and CompanyEnrich, and you hit coverage no single provider can match.

  • Coverage ceiling: 85–90% of B2B contacts
  • Order optimized for hit rate and cost per email
  • Fallback sources kick in only when earlier ones miss
  • Zero cost on misses with verified-only mode

Verification
SMTP verification on every email

Every email the waterfall returns runs through MX lookup plus SMTP ping before it reaches you. Catch-all domains, disposable addresses, and role-based emails (info@, support@) are detected and flagged — not silently delivered.

  • MX record lookup
  • SMTP handshake test
  • Disposable domain detection
  • Role-based address flagging
  • Catch-all domain detection

Inputs
Four ways to trigger an email lookup

Find business emails from almost any starting signal. ListPlus picks the best provider for the input type so you don't have to.

  • LinkedIn URL → email (Prospeo, ~2s)
  • First name + last name + company → email
  • First name + last name + domain → email
  • Full name on its own (best-effort via enrichment)
Four inputs for email lookup: LinkedIn URL, name+company, name+domain, full name
Bulk
Bulk email finder for lists of any size

Paste 10 rows or upload 100,000. ListPlus runs the waterfall in parallel, respects provider rate limits, and ships clean results with verification status and source attribution per row.

  • Paste list, upload CSV, connect Google Sheet, or call the API
  • Live progress bar per row
  • Parallel execution with per-provider rate limiting
  • Verification status + source per result

Compare

ListPlus vs. other email finders

Honest comparison — each of these tools is good at what it does. ListPlus is different because it combines them under one API instead of replacing them.

Hunter.io

Best for domain search and email pattern guessing. Coverage drops fast outside tech hubs. ListPlus includes Hunter-style lookups as one of 15+ cascading sources.

Snov.io

Strong for LinkedIn bulk extraction, but limited outside that channel. ListPlus handles LinkedIn lookups via Prospeo with full SMTP verification included.

Apollo

Huge contact database — bundled with outreach that most teams don't need. ListPlus uses Apollo data (via FullEnrich waterfall) without locking you into the outreach suite.

Lusha

Phone-first. Email coverage is a side product. ListPlus waterfalls through Lusha plus 14 others, so you never hit a provider's individual ceiling.

ContactOut

Deep on LinkedIn profile data, thin on company enrichment. ListPlus covers both in one flow via the same API.

Cognism

Strong EMEA phone data. Email finder is secondary. ListPlus waterfalls Cognism data alongside five other EMEA-strong sources.

Pricing — pay only for verified emails

Free plan includes 50 email lookups. Pro is €39/month for 5,000 records with full waterfall. Premium adds CRM sync, AI Agent API, and your own provider API keys (50-80% cheaper).

FAQ

Email finder — frequently asked questions

What is an email finder?
An email finder is a tool that returns a person's business email from inputs like their name, company, LinkedIn URL, or domain. ListPlus is a waterfall email finder — it cascades each lookup through 15+ providers (FullEnrich, Prospeo, Hunter, Apollo, Lusha, Cognism, ContactOut and more) until a verified address is found, then runs SMTP verification before delivering the result.
How accurate is the email finder?
ListPlus only returns SMTP-verified emails. Every result from the provider waterfall runs through MX lookup plus SMTP handshake. Catch-all domains and disposable addresses are flagged separately so you can decide whether to include them. Typical verified-email accuracy is 92-95%, compared to 70-80% for single-provider finders that don't verify.
How does waterfall email finding work?
For every lookup, ListPlus tries the most accurate provider for that input type first. If it returns no result, the next provider in the chain is called — and so on through 15+ sources. A single provider typically covers 40-60% of B2B contacts. A waterfall covers 85%+, because providers overlap differently and coverage gaps rarely align.
Can I find emails from LinkedIn URLs?
Yes. Paste a LinkedIn profile URL and ListPlus returns the verified business email in under two seconds via Prospeo. If Prospeo misses, the waterfall falls back to Enrich.so, FullEnrich person lookup (name + company), and additional sources. You only pay when a verified email is returned.
Does ListPlus include email verification?
Yes — SMTP verification runs on every email before delivery. No separate tool or subscription needed. Disposable addresses, role-based emails (info@, support@), and catch-all domains are detected and flagged. Verified-only mode can be enabled so you only get charged for emails that pass all checks.
Is the email finder GDPR-compliant?
Yes. Infrastructure runs in Frankfurt (Germany) on AWS eu-central-1. All email lookups and verification happen in the EU, and personal data is auto-deleted after enrichment. ListPlus is data processor per GDPR Art. 28 with a standard DPA available on Premium.
How does pricing work for the email finder?
Free plan includes 50 email lookups and no credit card. Pro at €39/month covers 5,000 records with the full waterfall. On verified-only mode, misses cost nothing. Premium at €79/month lets you use your own Hunter, Apollo, or Lusha API keys — typically 50-80% cheaper than managed pricing.
Can I bulk-find emails from a list?
Yes. Paste a list of names and companies, upload a CSV, connect a Google Sheet, or call the API. ListPlus runs the waterfall in parallel with per-provider rate limiting, shows live progress, and delivers results with verification status and source attribution per row — ready to push to HubSpot, Salesforce, or Pipedrive automatically.
