Same SMTP check. Same catch-all handling. Credits that never expire. We just charge a fraction of what they do.

Three real buyer profiles. Twelve months of monthly purchases. The dollars-saved column is the answer.
Same SMTP verification, same deliverability after sending, fraction of the invoice. The math does the convincing.
"We integrated Kickbox into our signup flow back in 2019 and never looked at it again. Five years later I checked the billing page and we were paying $800 per 100k verifications. Tested Bulk Email Checker's API on the same traffic for a week. Same results. I still can't believe we let that run for five years without questioning it."
"Kickbox returned unknown on about 28% of a list we tested. Ran the same file through Bulk Email Checker and got 21%. Seven percent fewer question marks on the same data. That is seven percent more of your list you can actually make a decision on."
"Our contact form was getting hammered with fake signups. We needed real-time verification on every submission but Kickbox doesn't offer a flat-rate API. At our volume the per-check cost was adding up to more than the leads were worth. Switched to the unlimited API here and stopped worrying about the bill every time a bot hit our forms."

Depends on what you optimize for. If price-per-email matters most, we're typically 85%+ cheaper across every published tier. If credit-expiry has burned you, ours never expire. If you need a flat-rate Unlimited tier, we offer one and Kickbox doesn't. Try 25 verifications free in our dashboard and decide for yourself.
Per published list pricing, we are. $2.95 for 1,000 verifications scaling to $409.95 for 1M, which is roughly 71-86% below Kickbox's tiers. The Pricing panel above has the full side-by-side.
No. They remain in your Kickbox account until used or until the 12 months (365 days) window closes. Nothing migrates automatically.
Lower overhead, lean operations, no acquisition pricing pressure. Our pricing structure has not changed on renewal in over a decade.
Both services perform SMTP-level mailbox verification with handshake-stage RCPT checks, MX validation, catch-all detection, disposable filtering, and role-address flagging.
One base URL change. Endpoint shapes match closely. Our docs include a side-by-side mapping for the common verification calls.
Yes. Most teams above 1M move to our Unlimited flat-rate API, which removes per-email billing in exchange for dedicated cloud capacity at a fixed monthly rate.
Yes. Our team accounts use a shared credit pool, so multiple users on the same account draw from one balance. No per-seat fees, no separate billing.
Simple. We own our own infrastructure and don't pay for advertising. The price reflects that.
Not a dollar on Google Ads. Not a dollar on Facebook. No sales floor, no affiliate kickbacks, no conference booths, no influencer deals. Nothing.
Every other vendor in this category bakes these into their pricing. We don't carry any of them, so neither does the price tag.
We focus on one thing: email verification.
No platform pivots, no second product line, no marketing or sales departments to feed. Our biggest source of new customers is existing customers spreading the word. Over 400,000 customers and growing every single day.
Identical verification. Dramatically smaller invoice.
