Where they pull apart

Kickbox

Stands out: Unknown results are refunded as credits, so you do not pay for a check that returns no clear answer.

Watch out: Packs are paid upfront, not billed monthly. Very large volumes move to custom pricing through sales.

Not the right fit for

Buyers who want a flat monthly subscription
Teams that need lead search and verification together

MillionVerifier

Stands out: Risky results are refunded, credits never expire, and catch-all checks are included at no extra cost.

Watch out: You pay upfront for a pack, not a monthly plan. The $39 entry pack is 10,000 credits, so small one-off lists cost more per email.

Not the right fit for

Teams that only verify a few hundred emails
Buyers who want lead search built into the verifier
