ZeroBounce alternative
The ZeroBounce alternative that resolves catch-alls.
ZeroBounce is a capable deliverability platform. People go looking for an alternative for four fairly consistent reasons: results disappear after 30 days, the bill covers a suite they are not using, the entry price per email is steep, and a quarter of every B2B list comes back as catch-all with no verdict attached.
If any of that is why you are here, this page covers what changes when you switch and how to migrate without paying to re-verify a list you have already paid for.
The honest reasons
Why teams leave ZeroBounce.
None of these make ZeroBounce a bad product. They are structural choices that suit some teams and actively work against others.
01
Results expire after 30 days
ZeroBounce retains bulk validation results for 30 days, after which the file is no longer downloadable from your account. If you verify a list in January and want to re-segment it in March, the work is gone and the addresses have to be paid for again. Teams that verify in bulk and send in waves feel this first, because the sending calendar rarely matches a 30-day retention window.
02
You pay for features you do not use
ZeroBounce is a deliverability suite. Data append, AI scoring, inbox placement testing, DMARC monitoring and a blacklist monitor all sit inside the same price. Those are real products and some teams use all of them. If you came for verification and nothing else, the per-email rate is carrying the cost of a platform you are not touching.
03
Catch-alls come back unresolved
ZeroBounce detects that a domain accepts mail for any address and returns a catch-all status. That is accurate reporting, and it is where the answer stops. The specific mailbox is never tested, so you are left deciding whether to send blind or drop the lead. On B2B lists that segment is routinely 25 to 30 percent of everything you paid to verify.
04
The entry price per email is high
At the 2,000-credit tier ZeroBounce works out to roughly $0.008 per email. That is the tier most teams start on while they are still evaluating, so the first impression of cost is the worst one the pricing table offers. The rate improves at volume, but only if you can commit to volume before you have proof the results are worth it.
The other side
What you get when you switch.
Each answer maps to one of the four reasons above, in the same order.
Results stay available
Verified lists remain in your dashboard for export. Re-segment a list months later and download it again without paying twice for the same addresses.
You pay for verification only
No data append, no AI scoring tier, no deliverability suite folded into the rate. Credit packs with a published per-email price, and the full product on every pack.
Catch-alls get a verdict
A primary SMTP engine handles the clear-cut addresses, then a proprietary catch-all resolution engine re-tests the ones that came back ambiguous, turning unknown into deliverable or risky.
Entry pricing starts lower
The smallest pack is 1,000 credits at $7, which is $0.0070 per email with no subscription attached and no minimum to commit to first.
When ZeroBounce is still the right call
Switching is not automatically the answer. If your team uses the wider platform, staying is the cheaper decision. ZeroBounce covers inbox placement testing, blacklist monitoring, DMARC reporting and data append inside one contract, and replacing four tools with a verifier plus three point solutions rarely nets out ahead. The same applies if your role needs an enterprise procurement path, formal SLAs or SOC 2 documentation on file, which LeadList Verifier does not currently offer.
The switch case is narrower and more specific: you buy verification and only verification, your lists are B2B enough that the catch-all segment is material, and the 30-day retention window keeps costing you re-verification on lists you already paid for. If that describes the situation, the rest of this page is worth reading. If it does not, keep the suite.

Run the numbers
What the catch-all segment is worth.
On a 10,000-address B2B list, ZeroBounce typically returns more than 2,500 addresses as catch-all or unknown. Those are not bad addresses. They are addresses nobody tested. Our second pass resolves about 72 percent of that segment into a definitive verdict.

The relevant metric
Both runs verify the same 10,000 addresses. One returns 7,500 actionable verdicts, the other returns roughly 9,300 for ten dollars less. The gap is about 1,800 addresses that were already in a list you paid to verify and were sitting behind a status rather than an answer.
Figures assume a 25 percent catch-all rate and 72 percent second-pass resolution. Catch-all density varies by industry and list source, and B2C lists tend to be far lower, which narrows the gap considerably.
Migration
Moving off ZeroBounce.
Four steps, and only one of them costs credits. Do the export first, because the 30-day retention window is working against you.
01
Export your last ZeroBounce run
Download the validation results as CSV while they are still inside the 30-day window. Keep the full file, not just the deliverable rows, because the segment you need next is the one ZeroBounce could not answer.
02
Split out catch-all and unknown
Filter the export to rows where the status is catch-all or unknown. On a typical B2B list this is 2,000 to 3,000 rows out of 10,000. Everything ZeroBounce marked valid or invalid is already settled and does not need re-testing.
03
Re-verify only that segment
Upload the filtered file here and run two-pass verification. You are paying for a quarter of the list, not the whole thing, and the 100 free credits on signup cover a meaningful sample before you spend anything.
04
Merge the recovered rows back
Export the results and join them to your original file on the email column. The addresses that moved from catch-all to deliverable are net new sendable leads that were already sitting in a list you had paid to verify once.
FAQ
ZeroBounce switching questions.
What is the best ZeroBounce alternative for catch-all domains?
Look for a verifier that resolves catch-all addresses rather than reporting them. ZeroBounce detects that a domain accepts all mail and returns a catch-all status without testing the specific mailbox. LeadList Verifier runs a second pass over that segment using a proprietary catch-all resolution engine and returns a definitive deliverable or risky verdict for roughly 72 percent of it.
Is LeadList Verifier cheaper than ZeroBounce?
At comparable volumes, yes. As of May 2026, ZeroBounce is $16 for 2,000 credits, $65 for 10,000, $390 for 100,000 and $2,400 for 1,000,000. LeadList Verifier is $7 for 1,000, $55 for 10,000, $360 for 100,000 and $1,899 for 1,000,000. The larger difference is that LeadList Verifier credits never expire and results are not deleted after 30 days.
Do I lose my ZeroBounce results when I switch?
Export them before you cancel. ZeroBounce keeps bulk results for 30 days, so download the CSV while it is still available. Once you have the file, the deliverable and invalid rows carry over as settled results and only the catch-all and unknown segment is worth re-verifying.
Does LeadList Verifier offer data append or DMARC monitoring?
No. LeadList Verifier does verification and nothing else. If your team relies on ZeroBounce for data enrichment, inbox placement testing or DMARC monitoring, those are genuine reasons to stay, or to keep ZeroBounce for that work and route verification here.
How long does a 10,000-address list take to verify?
Ten to fifteen minutes for a full list, running 20 concurrent primary checks alongside 5 concurrent catch-all checks. Progress updates live in the dashboard every 5 seconds, and if a job fails partway the credits are refunded automatically.
Can I test before moving my whole workflow?
Yes. Every account starts with 100 free credits and no card is required. Run them against the catch-all segment of a list ZeroBounce has already processed, which is the sharpest possible test because it isolates the exact addresses your current tool could not resolve.
