EmailListValidation Validates Lists.1Lookup Validates Intelligently.
EmailListValidation provides bulk email validation services, but 1Lookup delivers superior real-time validation with advanced intelligence and fraud detection. While EmailListValidation focuses on batch processing, 1Lookup provides instant API validation plus multi-service intelligence for modern applications.
Real-Time Intelligence
While EmailListValidation requires batch processing and file uploads, 1Lookup validates emails one at a time over the API, with fraud signals on the same call. Perfect for form validation, user registration, and security workflows that need immediate intelligence.
Superior Accuracy & Platform
Experience Enterprise deliverability accuracy vs. EmailListValidation's 95%, plus validation for phone, email, and IP in one platform. Our AI-powered algorithms deliver better protection and multi-service intelligence.

Every lookup returns a risk signal, not just valid or invalid
A number can be perfectly well-formed and still be a burner, a VOIP line opened this morning, or a number other businesses have already reported. 1Lookup returns a risk score, a spam indicator and line type on the same call as the validation, so the decision to block, challenge or allow can be made in one request.
Real-time Risk Scoring
Instant fraud probability assessment for every number
Pattern Recognition
Detect suspicious behavior patterns across millions of numbers
Adaptive Learning
AI that improves fraud detection accuracy over time
Example response
One credit balance
Every product below draws from the same credits, at $0.00200–$0.00495 per credit depending on plan.
- Phone validation1 credit
- Email verification1 credit
- IP intelligence1 credit
- Spam and risk score1 credit
Buy credits once, spend them on whatever you need to check
Most validation tools sell one channel, so a team checking phones, emails and IPs ends up with three vendors, three invoices and three unused balances. 1Lookup bills all of them from a single credit pool on a monthly plan, with no contract, and leftover credits carry into the next quarter instead of expiring at midnight.
Phone, email and IP on one API
One key, one balance, one integration
Phone data refreshed daily
From FCC and carrier sources
No contract
Monthly plans, with three-month credit rollover
A full line profile, not a status code
The same call returns HLR data, subscriber status, porting history, network type and roaming state. That is the difference between knowing a number is formatted correctly and knowing whether a message sent to it will arrive.

Simple Migration from EmailListValidation
const formData = new FormData();
formData.append('file', emailList);
const upload = await fetch(
'https://api.emaillistvalidation.com/v1/upload',
{method: 'POST', body: formData}
);
// Wait for batch processing
`https://api.1lookup.io/v1/email/validate`,
{
method: 'POST',
headers: {'X-API-Key': key},
body: JSON.stringify({email})
}
);
What migrating from EmailListValidation actually involves
Both are REST APIs returning JSON, so the move is a URL, a key and a field mapping rather than a rewrite. The call above is the real shape of each request. Where the work usually goes is the response: our field names differ, and anything you were deriving from a status code may already be a field you can read directly.
One endpoint per channel
Phone, email and IP, same key and same balance
Email Support to Dedicated CSM
Support level rises with the plan, not with a separate fee

EmailListValidation vs 1Lookup FAQ
Common questions about EmailListValidation and switching to 1Lookup
What is EmailListValidation?
EmailListValidation is an email verification service that cleans mailing lists by detecting invalid, mistyped, disposable, and risky email addresses before you send. It supports both bulk list cleaning through file uploads and real-time verification through an API, and it advertises high deliverability accuracy backed by a money-back guarantee. Marketers and senders typically use it to reduce bounce rates and protect their sender reputation.
How much does EmailListValidation cost?
As of publication, EmailListValidation uses pay-as-you-go, credit-based pricing that starts around $0.001 per email, with a small minimum purchase to get started and volume discounts as your list grows. Monthly subscription plans are offered at a lower per-email rate than pay-as-you-go, and new accounts receive a limited batch of free credits to test the service. Because pricing is volume-tiered, your actual cost depends on how many addresses you verify.
What is the best EmailListValidation alternative?
The best alternative depends on your needs, but 1Lookup is a strong option for teams that want more than email verification alone. Instead of validating only email addresses, 1Lookup checks phone numbers, emails, and IPs through one API and one universal credit system, with data refreshed daily from FCC and carrier sources. A 7-day free trial lets you compare results against EmailListValidation before you commit.
How is 1Lookup different from EmailListValidation?
Both services validate email addresses well, and EmailListValidation is focused specifically on email list hygiene. 1Lookup’s main difference is scope: it unifies phone, email, and IP verification in a single API and one credit system, and adds carrier/HLR lookup, reverse lookup, and fraud/IP intelligence. That makes 1Lookup a better fit when you need real-time validation across multiple data types rather than email cleaning alone.
Can I try 1Lookup for free?
Yes. 1Lookup offers a 7-day free trial so you can test phone, email, and IP verification with your own data before paying. You can sign up and start validating through the single API and shared credit system right away, which makes it easy to benchmark 1Lookup against EmailListValidation.

The same month, priced both ways
Pick one of EmailListValidation’s own published volumes. Their figure is their published price at that tier; ours is the cheapest plan on our rate card that covers it. Nothing here is interpolated.
1Lookup
$99/mo
The Starter plan, 20,000 credits a month at $4.95 per 1,000. Using 2,500 of them is 13% of the plan, so $39.60 per 1,000 effective.
EmailListValidation
$19
Their published price for “2,500 credits”, at $7.60 per 1,000.
At 2,500 a month, EmailListValidation is $80 cheaper. Our smallest plan that covers this volume includes 20,000 credits, so the gap closes as you use more of it.

Before you sign: EmailListValidation and 1Lookup on the operational terms
The terms that decide what a year actually costs, rather than what the first month does. A blank means we could not verify it on either product’s published pages, not that the answer is nothing.
| Term | 1Lookup | EmailListValidation |
|---|---|---|
| Minimum commitment | None. Monthly plans with no contract and no minimum volume; cancel any time | Minimum purchase is 2,500 credits ($19 pay-as-you-go). No minimum contract term published. |
| Cost per extra seat | — | No per-seat charge. 'Team accounts let you invite your colleagues to collaborate in the same workspace while drawing from one shared pool of credits, with no extra per-seat fees.' |
| API access | Included on every plan and during the free trial; there is no tier that unlocks it | API is available on all plans with no tier gate. 'API verifications draw from the same credit pool as dashboard verifications — one credit per email, with the same volume discounts.' |
| Rate limit | 1,000 requests per minute on standard accounts, with higher limits available on request | No per-request rate limit published. The API page answers 'Is the API rate-limited?' with 'our infrastructure verifies over 100,000 emails per hour per customer. If you expect sustained bursts beyond that, contact us and we'll provision capacity.' |
| Compliance | — | GDPR (help centre states 'Email List Validation is 100% compliant with the GDPR'). No SOC 2, ISO 27001, HIPAA or named DPA published. |

Enterprise adds a dedicated account manager. No public support email or phone number listed. |
EmailListValidation fine print worth reading twice
Published terms that change what EmailListValidation costs or what you can do with it. Each one links to the EmailListValidation page it was read on, because a claim about somebody else’s contract should be checkable in one click.
The 'credits never expire' promise covers pay-as-you-go only; the terms state 'Pay-as-you-go credits never expire. Monthly subscription credits renew each billing cycle', so unused monthly credits are not stated to carry over.
