Kickbox Validates Emails.1Lookup Validates Intelligently.
Kickbox pricing at $50+ monthly adds up fast for high-volume validation. Customer reviews praise 1Lookup's superior accuracy and simple pay-as-you-go pricing. As the leading Kickbox alternative, we deliver faster response times, advanced fraud detection, and transparent pricing without complex credit systems.
Good tool, no fluff
Been using 1Lookup for a couple months now. We verify leads before pushing them into Pipedrive. Honestly it just works. Not fancy, not buggy, and the support actually answers when you write them. Can't really ask for more.
Brian LetzterUnited States · October 2025The most practical data tool I've used
I've seen hundreds of validation APIs come and go. 1Lookup stands out because they don't oversell. Their data is solid, support is honest, and they're transparent about limitations, which is rare in this industry. I've replaced three tools with this one. They listen, they iterate, and they keep improving. You can feel there are actual engineers behind it, not just salespeople.
Bùi Thị Thanh NgọcVietnam · October 2025Solid phone validation API
We use 1Lookup inside our telemarketing app to verify numbers before they go to the dialer. Setup was simple and the results have been consistent. It's not overloaded with features, just fast, accurate, and reliable. Docs could be a bit deeper, but honestly, it works out of the box.
Dirk van MeerUnited States · December 2025Saved us from hundreds of spam signups
We run a SaaS product with free trials and were getting flooded with bots and fake users. After integrating 1Lookup, the difference was night and day. It quietly filters out junk signups without blocking legitimate customers. The support team even helped us fine-tune our risk thresholds on a quick Zoom call. Being honest, we couldn't ask for more.
Ido ShachamUnited States · January 2026A good addition to our workflow
1Lookup has been a good addition to our workflow over the last few months. We use it to verify IPs, emails, and phone numbers, which has noticeably cut down the time we spend chasing dead-end applications. It's reasonably priced and their support team is actually helpful. It's a very practical tool for what we need.

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 Kickbox
What migrating from Kickbox 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

Kickbox vs 1Lookup FAQ
Common questions about Kickbox and switching to 1Lookup
What is Kickbox?
Kickbox is an email verification service that checks whether email addresses are valid and deliverable before you send to them. It flags risky, disposable, role-based, and free-provider addresses and returns a deliverability result and quality score through its API or bulk list-cleaning tools. Teams use it mainly to reduce bounces and protect sender reputation for email marketing.
How much does Kickbox cost?
As of publication, Kickbox uses a credit-based, pay-as-you-go pricing model that starts around $5 for 500 verifications (roughly $0.01 per email), with lower per-verification rates at higher volumes and custom quotes for enterprise needs. New accounts also receive a small batch of free verifications to test the service. Because pricing and credit terms can change, check Kickbox’s official pricing page for the current rates.
What is the best Kickbox alternative?
The best alternative depends on what you need to verify. If you only clean email lists, Kickbox is a strong, focused option; if you also verify phone numbers and IP addresses, 1Lookup covers email, phone, and IP through one API and one universal credit system. Teams consolidating several verification vendors often choose 1Lookup to avoid juggling separate tools and credit pools.
How is 1Lookup different from Kickbox?
Kickbox specializes in email verification, while 1Lookup is a broader data-verification API that validates emails, phone numbers, and IP addresses through a single API and one shared credit system. 1Lookup also offers carrier/HLR lookup, reverse lookup, and fraud/IP intelligence, with data updated daily from FCC and carrier sources. Both handle email validation well; 1Lookup’s edge is unifying phone, email, and IP checks in one place.
Can I try 1Lookup for free?
Yes. 1Lookup offers a 7-day free trial so you can test email, phone, and IP verification before you commit. The same universal credit system applies across every lookup type, so your trial credits work for whatever you need to validate.
Is Kickbox worth it in 2026?
Kickbox is worth it for deliverability-focused senders who want more than a checker: unknown results are refunded, the compliance posture is strong (SOC 2, GDPR, infrastructure in both the US and EU), and it is proven at enterprise scale with customers like Reddit and Mulesoft. The trade-off is the buying shape: purchased credits expire 12 months from purchase, purchases are non-refundable, and per-unit pricing runs higher than some rivals at $7.00 per 1,000 at the 10,000 tier, with the roughly $3 per 1,000 rate only reached at 1M volume. It is also email only, with no phone or IP products. Teams that need multi-channel checks or dislike expiring credit blocks often fit better with a per-lookup API like 1Lookup that spans email, phone, and IP.
The Superior Kickbox Alternative
Switching from Kickbox gets you more than email checks. One API and one credit system cover email, phone, and IP validation, with results cached for 7 days. Try it free for 7 days.

For scale: 1Lookup’s plans work out to $4.95 per 1,000 lookups on Starter down to $2.00 per 1,000 on Enterprise, with every lookup type (phone, email, IP, spam) drawing from the same credits. Pricing models differ (subscription vs pay-as-you-go), so compare at your real monthly volume.
The same month, priced both ways
Pick one of Kickbox’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 10,000 of them is 50% of the plan, so $9.90 per 1,000 effective.
Kickbox
$70
Their published price for “10,000 verifications”, at $7 per 1,000.
At 10,000 a month, Kickbox is $29 cheaper. Our smallest plan that covers this volume includes 20,000 credits, so the gap closes as you use more of it.
Kickbox rates as published on kickbox.com, verified July 2026. Pricing models differ (a monthly plan is not a credit pack), so a like-for-like month depends on your real mix of lookups. Check their pricing page
Kickbox’s pricing page, as we read it

Before you sign: Kickbox 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 | Kickbox |
|---|---|---|
| Minimum commitment | None. Monthly plans with no contract and no minimum volume; cancel any time | No minimum term published for self-serve credit purchases. The Master Services Agreement runs for the duration of use and terminates on termination of any Statement of Work or 60 days after all verification credits expire. Enterprise customers contract through Statements of Work or custom agreements. |
| Going over your quota | — | No overage billing published. Credits are prepaid and the verification API returns a "Balance Depleted" error message when credits run out; an optional Auto Recharge setting buys further credits automatically. |
| API access | Included on every plan and during the free trial; there is no tier that unlocks it | No tier gate published. The verification API is documented for all accounts and a Sandbox Mode is available for testing without consuming credits. |
| Rate limit | 1,000 requests per minute on standard accounts, with higher limits available on request | 25 parallel requests per IP address, plus a separate limit of 8,000 requests per clock minute. Exceeding either returns HTTP 429 Rate Limit Exceeded, and the docs state you can immediately retry. |
| Uptime SLA | — | 99.9% guaranteed API uptime SLA for enterprise customers using the Kickbox API |
| Compliance | — | The pricing page states Kickbox is "fully GDPR-compliant and SOC II certified" and footer badges show SOC II Compliant, M3AAWG membership and GDPR. The docs Security and Compliance page instead refers to "our current progress towards SOC2 compliance" and describes Kickbox as "CCPA and GDPR ready". Dedicated EU servers and an EU app are offered for EU customers. |
| Support | Starter: Email Support; Growth: Priority Email & Chat Support; Professional: Chat + Live Meeting; Enterprise: Dedicated CSM | Support via live chat and email (support address published in the docs). The pricing page lists "First Class Support" for all accounts. Enterprise customers additionally receive a dedicated account manager and priority technical support. |
Kickbox fine print worth reading twice
Published terms that change what Kickbox costs or what you can do with it. Each one links to the Kickbox page it was read on, because a claim about somebody else’s contract should be checkable in one click.
Email verification credits automatically expire one year from the date of purchase, a term stated only in the Master Services Agreement and not on the pricing page.

Who this is for
A quick, honest read on which tool fits your use case.

Consider Kickbox instead if: email list hygiene is your only goal and you want a focused, deliverability-first email verifier.
