Kickbox vs Verifalia (2026): which should you pick?

Pick Kickbox if

• Fits if you check sign-ups in real time and want a sandbox to test against
• Works for teams on Braze, Iterable or Klaviyo who want checks built in

Look elsewhere if

• Pricey if you clean big lists, as a million checks cost $2,999
• Not for you if you need warm-up, placement tests or DMARC tools as well
• Watch out: Threat Score costs one more credit when it finds a signal, which can double the price of an address
• Tight if you want a monthly plan, as only one-off packs are listed
• Tight if you want to try it on a real list, as only the first 100 checks are free

Pick Verifalia if

• Fits if you clean a list now and then and want credit packs that do not expire
• Works for developers who want to verify addresses at signup through an API

Look elsewhere if

• Tight if you want more than 25 free checks a day, because the allowance resets daily and does not roll over
• Watch out: higher quality levels use more credits per address, so the headline price per check goes up
• Skip it if you want an app on your phone or desktop, as it is a web client and API only
• Pricey if you clean big lists often: Enterprise is $199 a month and Ultimate $499, before any credit packs
• Watch out: the pricing page shows monthly-billing prices nowhere we could read, only per month billed yearly

Kickbox

• Only pay-as-you-go packs are listed; there is no monthly plan on the pricing page.
• Kickbox verifies addresses only; it has no warm-up, inbox placement testing or DMARC tools.
• Threat Score can double the cost per address when it finds a signal.

Verifalia

• Every plan includes only a daily allowance of credits that expires at day's end; anything beyond it is bought as credit packs, such as 10,000 credits for $49.90.
• One credit covers one standard-quality check; higher quality levels cost more per address.
• The pricing page shows plan prices as per month billed yearly; the monthly-billing prices were not displayed when read.
• Web client area and API only; there is no desktop or mobile app.

Kickbox

List verification

Upload a list and Kickbox sorts each address by deliverability; the vendor says 100,000 addresses take about an hour.

Verification API

Checks addresses at sign-up in real time, with a sandbox mode for testing without spending credits and a free endpoint for spotting disposable domains.

Threat Score

Flags addresses linked to abuse, complaints or a poor sending reputation, for one extra credit only when a threat signal is found.

Native integrations

Verifies lists inside Mailchimp, Klaviyo, HubSpot, Braze, Iterable, SendGrid and others, with more through Zapier.

Deliverability consulting

Deliverability audits and consulting from Kickbox's own team are offered as a separate service beside verification.

Verifalia

Bulk list cleaning

Upload a list as plain text, CSV or Excel (.xls or .xlsx), up to 100 MB per list, then download the results and choose which addresses to keep.

Real-time verification API

A real-time API with free, open-source SDKs for .NET, Go, Java, JavaScript, PHP and Ruby, usable for single checks or for batches.

Detailed status codes

Each address is marked Deliverable, Undeliverable, Risky or Unknown and given one of more than 40 status codes with an explanation.

Quality levels

Standard, High and Extreme levels trade more credits for extra attempts on mail servers that give temporary or unclear answers.

Disposable, free-mail and typo detection

Flags disposable and free-mail addresses, suggests fixes for common typos, and removes duplicates at no charge.

Classification overrides

Wildcard rules such as *@example.com set how matching addresses are classified; the rule limit runs from 5 to 100 depending on the plan.
