BounceHalt vs. ZeroBounce, NeverBounce, Bouncer & MillionVerifier
Choosing an email verification API for cold outbound or deliverability? The number that matters isn't a marketing accuracy claim — it's your real bounce rate after sending, ideally under 2%. That comes down to how well a tool handles the hard cases: catch-all domains, Microsoft 365, Google Workspace, and SEG-protected inboxes. Here's how BounceHalt stacks up on price and what's included — then run your own test rather than trusting anyone's claims.
Price comparison
Normalized to cost per 1,000 verifications at ~100,000 volume, plus the two things buyers get burned on: credit expiry and the free tier.
| Provider | Price / 1,000 | Credits expire? | Free tier |
|---|---|---|---|
| BounceHalt | $2.29 credit pack · $1.49 on subscription | Never | 250 / month |
| ZeroBounce | ~$3.50 | Never | 100 / month |
| NeverBounce | ~$3.50 | After 12 months | 1,000 (one-time) |
| Bouncer | ~$3.25 (down to ~$2 at 1M) | Never | 100 (one-time) |
| Kickbox | ~$8.00 | After 12 months | 100 (one-time) |
| MillionVerifier | ~$1.29 (budget) | Never | Trial |
Competitor pricing, credit-expiry and free-tier figures are published terms, approximate and normalized to ~100,000 verifications, as of 2026 — providers change rates, policies and bundle tiers, so always confirm the current terms on each provider's site before deciding.

Where BounceHalt fits
We deliberately undercut every mid-tier verifier — ZeroBounce, NeverBounce, Bouncer and Kickbox — while including never-expiring credits, a 0–100 deliverability score with a safe_to_send flag, spam-trap and disposable detection, and a developer-first REST API — plus a recurring 250-checks-a-month free tier (Bouncer and Kickbox give 100 once; ZeroBounce gives 100 a month).
Rock-bottom budget tools like MillionVerifier or DeBounce can cost less per check, but they're barebones — fewer signals, lighter tooling, no recurring free tier. We're not going to claim we're more accurate than a tool you haven't tested on your own list. So we make it easy to find out: run a bake-off.

Run your own bake-off
Take a sample of your leads — a few hundred on the free tier (250/month, no card), or a credit pack for a full 5,000–10,000 run. Verify the same list with BounceHalt and any competitor, compare valid / invalid / catch-all rates, send only the approved emails from a warmed domain, and measure your actual bounce rate. Under 1–2%? You've found your verifier. That's the only benchmark that matters.
