EmailListVerify vs Kickbox
An independent, review-free comparison compiled by the SaaSTracker editorial team. Both products are profiled in full, and neither can pay for placement here.
The short answer
Both sides assessedEmailListVerify compared with Kickbox
Kickbox costs $500 for 100,000 addresses where EmailListVerify costs $168 to $186 for essentially the same checks. Kickbox adds a Ziff Davis parent, a SOC 2 posture, EU processing, roughly thirty native ESP connectors, scheduled automated cleaning, and a published refund on unknown results. Neither resolves catch-alls. If you need a vendor your security team will sign off on, pay the multiple; if you just need the list cleaned, EmailListVerify does the job for a third of the money.
Kickbox compared with EmailListVerify
EmailListVerify does the same core job at roughly a third of the price, with non-expiring credits and a similar ESP integration story. It is a small Slovak company with a thinner compliance posture and no refund policy on unknowns. If price per address is what you are optimising, EmailListVerify wins comfortably. If you need a vendor your security review will accept, Kickbox is worth the multiple.
Choose EmailListVerify if
Small and mid-sized marketing teams cleaning permission-based lists who want a competent, cheap, self-serve verifier with an API, ESP integrations, non-expiring credits, and a bag of free deliverability tools thrown in, and who do not need catch-all resolution or audited certifications.
Choose Kickbox if
Established email programmes at ecommerce, SaaS, and media companies that need a verifier their security team will approve, want native cleaning inside a major ESP, and care more about a predictable, defensible result than about the lowest possible price per credit.

| Setup time | Minutes. Register, use the 100 free credits on a sample, buy a package, upload a file. An ESP integration is a short OAuth flow. The API takes an hour or two to wire into a signup form and is available on the smallest plan. | Under ten minutes for a bulk clean: create an account, use the 100 free credits on a sample, buy a package, drag in the list. Connecting a native ESP integration adds a few minutes of OAuth. A real-time API integration on a signup form is a half-day job for a competent developer. |
| Learning curve | Very low. The result vocabulary is standard, the interface is plain, and there are no configurable quality levels or credit multipliers to reason about. The only judgement call is what to do with the catch-all segment, and the vendor's advice, skip it, is at least unambiguous. | Low. The four-state result model is the category standard, and the only concepts you have to learn are the Sendex score and the reason codes, both of which are documented. The judgement call, what to do with the risky segment, is a business decision Kickbox deliberately leaves to you. |

Strengths and limitations
EmailListVerify
Strengths
- Roughly a third the price of Kickbox and half the price of ZeroBounce for substantially the same core checks, with two fully published price ladders and no sales gate.
- The API is included on every plan including the smallest package, rather than gated behind an upgrade.
- Pay-as-you-go credits never expire, which suits agencies and project work far better than a subscription with a monthly allowance.
- An unusually broad set of free adjacent tools including inbox placement testing, blacklist checking, DMARC and SPF generation and validation, and an SPF flattening tool that solves a real DNS problem.
Limitations
- No catch-all resolution at all. The vendor detects accept-all domains and explicitly recommends skipping them, which leaves the risky bucket exactly where it was.
- No published policy on whether unknown or catch-all results consume credits, which is a meaningful gap for a vendor competing on price.
- Compliance stops at a GDPR statement. No SOC 2, no ISO 27001, no published data residency, retention window, or security contact.
- The published ladders stop at 100,000 pay-as-you-go and 250,000 per month on subscription, so genuinely high volume is not self-serve.
Kickbox
Strengths
- Refunding credits on risky and unknown results is the fairest billing policy in the category and removes the incentive to bill for non-answers.
- The largest and best-documented native ESP integration list of any verifier here, covering most platforms a mid-market marketing team is likely to run.
- Real corporate backing through Ziff Davis, with SOC 2, GDPR, a trust centre, a status page, US and EU processing, and a named team, which clears procurement in a way anonymous competitors cannot.
- The Sendex quality score and did-you-mean typo suggestion give you more to act on than a bare deliverable or undeliverable verdict.
Limitations
- No attempt to resolve catch-all addresses. Accept-all domains are detected and then abandoned, which makes Kickbox a poor fit for most B2B outbound work.
- The most expensive published ladder in this category at every volume, roughly five times MyEmailVerifier and three times EmailListVerify at 100,000 addresses.
- Credits expire after twelve months, unlike most competitors, which punishes buying ahead for a project that slips.
- Free allowance is 100 credits once, not 100 per day, so extended evaluation costs money.
Pricing compared
EmailListVerify
Two published ladders on the same platform: prepaid pay-as-you-go credits that never expire, and monthly subscriptions roughly 10 percent cheaper per credit that renew each month. One credit per address, API included on every plan.
- Free credits$0
- Pay as you go$5 to $186
- Monthly subscription$16 to $346
- Higher volumesOn request
EmailListVerify is priced exactly where it should be for what it does. It is not the cheapest, MyEmailVerifier and Reoon both undercut it by roughly half, and it is not the most capable, since it makes no attempt at catch-all resolution and publishes no certifications. What it offers is a well-rounded, competent product at roughly a third of what the establishment vendors charge, with the API included at every tier, non-expiring credits, ESP connectors, and a surprisingly useful pile of free deliverability tools attached. For a small marketing team cleaning a permission-based list, that combination is better value than either the budget floor or the premium ceiling. The unpublished credit policy on unknowns is the one thing that undermines a price-led pitch, and it is worth an email to support before you buy a large package.
Kickbox
Prepaid verification credits on a published volume ladder, bought self-serve with no subscription requirement, with credits refunded automatically on risky and unknown results.
- Free credits$0
- Entry volumes$5 to $150
- Mid volumes$275 to $1,100
- High volumes$1,800 to $2,999
Kickbox is expensive per credit and cheap per problem avoided, which is the correct way to read it. Against MyEmailVerifier at $99 for 100,000 or EmailListVerify at $186, paying $500 looks indefensible on a spreadsheet, and for a pure bulk clean of a consumer list it probably is. What the premium actually buys is vendor risk reduction: a Ziff Davis parent, SOC 2, EU processing, a support team, roughly thirty native ESP connectors, and a published policy of refunding credits it cannot resolve. If your list lives inside Klaviyo or Braze and your security team reviews vendors, that bundle is worth several times the price difference. If your list is a scraped B2B file full of accept-all domains, Kickbox is the worst possible value, because the segment you most need answered is the one it will refund your credits for and decline to touch.
Editorial verdict on each
EmailListVerify
EmailListVerify is the competent middle of this category, and there is more merit in that than the description suggests. It runs every check a permission-based marketing list needs, includes the API on the cheapest plan, sells non-expiring credits, connects to the ESPs small senders actually use, and costs about a third of what the establishment vendors charge for the same work. The free tools around it, particularly the inbox placement test, the blacklist checkers, and the SPF flattening utility, give a small team a rough deliverability toolkit they would otherwise buy separately. Two things keep it from being a default recommendation. It will not touch a catch-all domain, so B2B outbound teams should look elsewhere, and it does not publish whether unresolved results cost you a credit, which is a strange gap for a vendor whose entire pitch is price. Buy the $5 thousand-credit package, run a list you already know the answers to, and ask support the credit question. If both check out, this is a sensible, unglamorous purchase.

Kickbox is the safe, expensive, well-run choice, and it is honest about what it will and will not do. Refunding credits on risky and unknown results is the fairest billing policy in the category and should be table stakes everywhere; the Sendex score and typo suggestions give you more than a bare verdict; the ESP integration list and scheduled automations mean cleaning actually happens instead of being scheduled and forgotten; and the Ziff Davis parent, SOC 2 posture, and EU processing clear vendor reviews that anonymous competitors cannot. The two reasons not to buy it are both decisive when they apply. It is roughly three to five times the price of the budget field at every volume, and it will not touch a catch-all address. For a marketing team running a permission-based list inside Klaviyo, HubSpot, or Braze, that is a fine trade. For an outbound team whose value sits in the accept-all bucket, Kickbox is the most expensive way to be told no.
