Kickbox vs Listmint

Choosing between Kickbox and Listmint usually comes down to how each one deals with the addresses your list actually struggles with. Kickbox is a developer-first verifier with a clean real-time API and a deliverability score. Listmint is a verifier that reports catch-all outcomes as their own explicit status codes. Below we walk through how they price, what they do with catch-all addresses, and how accurate each claims to be, and we show where Giggal.ai lands on the same list so you have a third number to weigh.

Every price and policy here comes from the vendor's own pricing. Where a tool does not sell by volume, the cell shows "Quote only", "Per seat" or its monthly plan price instead.

How Kickbox and Listmint handle catch-all

Kickbox flags accept-all addresses with a field rather than resolving them. Listmint resolves catch-all addresses and returns them as catch_all_valid or catch_all_invalid. Catch-all domains accept mail for every name, so a normal check cannot tell a real mailbox from a dead one, and this is usually where a list quietly loses good contacts.

How Giggal.ai handles catch-all. Giggal.ai resolves catch-all addresses to a real deliverable or undeliverable result at 1.5 credits in a run, or 2 standalone.

Kickbox vs Listmint pricing

Kickbox is $70 at 10,000, $500 at 100,000 and $2,999 at a million. Listmint is sold by monthly plan, from Not published for 10,000 verifications a month. Both numbers come straight from each vendor's own pricing, so put them next to the volume you send each month.

How Giggal.ai prices it. Giggal.ai publishes a flat pay-as-you-go price, $9.90 at 10,000, $76 at 100,000 and $680 at a million, with credits that never expire.

Secure email gateway support

On enterprise domains a gateway like Mimecast, Proofpoint or Barracuda often sits in front of the mailbox and blocks the usual check. Kickbox does not cover those gateways, and Listmint does not.

How Giggal.ai handles gateways. Giggal.ai detects 15 named secure email gateways including Mimecast, Proofpoint and Barracuda, and returns a real result on addresses behind them.

Credits, free tiers and expiry

Kickbox does not publish a credit-expiry policy, and offers 100 verifications to start. Listmint does not publish a credit-expiry policy, and lists no free tier.

How Giggal.ai treats credits. Giggal.ai credits never expire, it does not charge for unknown results, and every list starts on 1,000 free credits with no card.

Why teams pick Giggal.ai over both

Kickbox and Listmint each leave a pile of catch-all and gateway-protected addresses unconfirmed. Giggal.ai returns a real result on those at 1.5 credits, verifies behind 15 secure email gateways, and publishes a flat $9.90 per 10,000 with credits that never expire.
