Email Verifier — Zero Bounce Rate for 1 Cent, Not $1

They charge $0.008 per email. We charge $0.01 for a hundred.

Same SMTP technology. Same accuracy. Same catch-all detection. 80x less money leaving your wallet.

The "premium" tools hope you never do this math. Now you have.

Built by GeniusLead.de — B2B lead generation that actually makes sense.

The Math They Don't Want You To See

Let's talk about what email verification actually is: Your server sends a TCP packet to port 25. The mail server says "yes" or "no." That's it. That's the whole technology.

Now let's talk about what "premium" tools charge for this TCP packet:

	This Tool	Tool Z*	Tool N*	Tool M*
1,000 emails	$0.10	$8	$8	$3
10,000 emails	$1.00	$65	$50	$29
100,000 emails	$10.00	$350	$300	$189
SMTP Verification	Yes	Yes	Yes	Yes
Disposable Detection	Yes (500+)	Yes	Yes	Yes
Catch-All Detection	Yes	Yes	Yes	Yes
Role-Based Detection	Yes	Yes	No	No
Typo Auto-Correction	Yes	Yes	No	No
Free Provider Flagging	Yes	No	No	No
DACH-Optimized	Yes	No	No	No
API Key Required	No	Yes	Yes	Yes
Credit Card Required	No	Yes	Yes	Yes

*You know exactly which tools these are. They charge 80x more for sending the same TCP packet.

$0.01 per email. $1 for 10,000. That's the actual cost of verification.

The rest? That's their marketing budget. Their office in Vegas. Their Series B investors expecting 40x returns on your email list.

7-Layer Deep Verification

Every email goes through 7 checks — more than most "premium" tools:

YOUR EMAIL                john.doe@gmial.com
      |
      v
  1. RFC 5322 SYNTAX        Valid format? Yes
      |
      v
  2. TYPO DETECTION          "gmial.com" --> Did you mean "gmail.com"?
      |
      v
  3. DISPOSABLE CHECK        tempmail.com? guerrillamail? 500+ domains checked
      |
      v
  4. ROLE-BASED CHECK        info@? sales@? support@? Flagged.
      |
      v
  5. FREE PROVIDER CHECK     Gmail? GMX? web.de? Flagged.
      |
      v
  6. MX RECORD LOOKUP        Does the domain have a mail server?
      |                      (with A-record fallback)
      v
  7. REAL-TIME SMTP CHECK    Connect to mail server. Ask if mailbox exists.
      |                      Detect catch-all servers.
      v
  RESULT                     valid | invalid | catch-all | unknown
                             + score 0-100 + detailed reason

Why Does This Exist?

Because we got tired of paying rent on someone else's TCP connection.

Email verification is a solved problem. The code is simple. The infrastructure costs pennies. Yet somehow it became a $100M+ industry charging $0.008 per "yes or no" answer.

We built this for GeniusLead — our B2B lead generation platform. We needed to verify millions of emails. We looked at the prices. We laughed. Then we built our own.

Now you can use it too.

$0.01 per email. Not $0.008. Not $0.003. One cent. For a hundred emails.

How to Use

Simple — Paste and Go

Paste emails separated by commas, newlines, or semicolons:

john@example.com, jane@company.de
max.mueller@firma.de
fake@tempmail.com; info@apple.com

Bulk — Up to 10,000 Emails

Paste your entire list. The Actor processes them in parallel with real-time SMTP verification.

Programmatic — JSON Input

{
  "emails": ["john@example.com", "jane@company.de", "max@firma.de"],
  "concurrency": 15,
  "timeout": 12
}

Input

Parameter	Type	Required	Default	Description
emails	string	Yes	—	Emails to verify (comma/newline/semicolon separated)
concurrency	number	No	10	Parallel checks (1-20). Higher = faster.
timeout	number	No	10	Seconds per SMTP check (1-30).

Output — What You Get Back

Every email returns a full verification report:

{
  "email": "john.doe@gmail.com",
  "status": "valid",
  "valid": true,
  "score": 90,
  "reason": "Email address verified via SMTP",
  "isDisposable": false,
  "isRoleBased": false,
  "isFreeProvider": true,
  "isCatchAll": false,
  "hasMxRecords": true,
  "syntaxValid": true
}

Disposable Caught

{
  "email": "test@guerrillamail.com",
  "status": "invalid",
  "valid": false,
  "score": 5,
  "reason": "Disposable/temporary email domain",
  "isDisposable": true
}

Typo Detected

{
  "email": "john@gmial.com",
  "status": "invalid",
  "valid": false,
  "score": 5,
  "reason": "No MX or A records",
  "typoSuggestion": "john@gmail.com"
}

Role-Based Flagged

{
  "email": "info@big-company.de",
  "status": "valid",
  "valid": true,
  "score": 85,
  "reason": "Email address verified via SMTP",
  "isRoleBased": true
}

Score Guide

Score	Verdict	What To Do
90-100	Verified	Safe to send
70-89	Likely valid	Send — minor flags (role-based or free provider)
50-69	Catch-all	Server accepts everything — can't confirm this specific address
20-49	Risky	Greylisting or timeout — consider removing
0-19	Dead	Invalid, disposable, or no mail server. Do not send.

Pricing

$0.01 per email verified. That's it.

Emails	Cost Here	Cost at "Premium" Tools
1,000	$0.10	$3 - $8
10,000	$1.00	$29 - $65
50,000	$5.00	$150 - $300
100,000	$10.00	$189 - $350

You save 80-97% on every single verification. Same SMTP check. Same result. Different price.

Technical Details

• Real-time SMTP — direct connection to mail servers on port 25
• MX Priority Sorting — tries highest-priority mail server first
• A-Record Fallback — for domains without MX records
• 5-Minute MX Cache — same domain = one DNS lookup (fast for bulk)
• Catch-All Probe — random address test to detect catch-all servers
• Zero external APIs — no third-party dependencies

Limitations

• Gmail/Google Workspace — often returns catch-all (Google doesn't reject at SMTP level)
• Rate limiting — aggressive mail servers may throttle. Use concurrency 5-10 for sensitive domains.
• Accuracy — 85-95% industry standard. Catch-all domains reduce certainty.
• For best results on large lists: concurrency 10, timeout 15s.

FAQ

Why only $0.01? Because that's what it actually costs. The other tools aren't charging for technology — they're charging because you didn't know any better. Now you do.

How does this compare to "premium" tools? Same core technology (SMTP verification). We add DACH-specific typo detection and free provider flagging they don't have. They add proprietary checks (spam trap scores) that require expensive third-party data. For 95% of use cases, the result is identical. The price is not.

Can I do 100,000 emails? Yes. Split into batches of 10,000. Set memory to 2-4 GB and concurrency 10-15. Total cost: $10.

Does it work with German business emails? Absolutely. Built and tested for DACH markets. Handles Umlauts, German TLDs, and DACH-specific providers.

Why should I trust a $0.01 tool? Because the $0.008 tool uses the same SMTP check. The price difference isn't quality — it's margin. We run this on dedicated infrastructure with zero middlemen. You get the same TCP packet for less.
