Is FindLeadEmails a Kickbox replacement?

For verifying outbound prospect lists, yes. For email-marketing deliverability tooling beyond verification, Kickbox covers more.

Does FindLeadEmails send an email to verify an address?

No. The check talks to the receiving mail server and stops before any message is delivered.

Why outbound teams switch

Marketing verification and outbound verification are not quite the same job. A marketing list is people who gave you their address. An outbound list is people you found, where the address itself is the uncertain part. That is where a finder-plus-verifier earns its keep:

An invalid result can be repaired by trying the other patterns for that person's company.
A catch-all domain is labelled honestly and free, rather than counted as a pass.
A row with no address becomes a lookup, not a skipped line.

How verification is billed here

Import a CSV into a table, add a Verify email column, and every row gets one of four verdicts: valid, invalid, catch-all, or unknown. A check costs 0.25 credits, and only a definitive answer is billed. Catch-all and unknown results are refunded automatically, because the upstream check does not tell anyone anything there either.

That works out to $2.25 per 1,000 checks on the $9 Launch plan and $0.87 per 1,000 on Volume. Credits never expire, and the same wallet pays for finding emails when the address is missing in the first place. To try a single address first, the free email verifier runs without an account.

Verifying a list versus finding the address

A verifier answers one question: does this mailbox exist? It needs the address up front. Most outbound lists have gaps: a name and a company, but no email, or an old address for someone who has moved on. A pure verifier marks those rows invalid and stops.

Here the same row can go one step further. When the address is missing or comes back invalid, the finder generates the company's likely email patterns, checks each against the mail server, and returns the one that is accepted. You pay $3.49 per 1,000 found-and-verified emails at the best published rate, and nothing for a miss.
