WizLeads VS

Looking for the best DeBounce alternative?

Why users prefer WizLeads?

852 kept

per 1,000 emails

DeBounce kept 670 on the same list, rejecting a third of the file — a 0.10% bounce rate to our 0.60%.

Catch-all resolution

no 10-credit surcharge

DeBounce bills catch-all validation at 10 credits per check. WizLeads includes it.

26% lower price

per 100,000 verifications?

$99.50 on the WizLeads Cartel plan against DeBounce's $135 for the same 100,000 verifications.

SEG detection

all major SEGs flagged

Proofpoint, Barracuda, Mimecast, Appriver, Sophos and other SEGs identified on every row.

Where DeBounce falls short

Sourced from our 1,000-email verification benchmark and DeBounce's published pricing

330 addresses rejected per 1,000

DeBounce marked a third of the list unusable. WizLeads rejected 148 of the same 1,000. On a 10,000-email file that should be about 1,800 more prospects removed from your reach.

Catch-all checks cost 10x

DeBounce prices standard validation at 1 credit and catch-all validation at 10 credits per check. On B2B lists, where catch-all domains are common, the line item that matters most is the one billed at ten times the rate. WizLeads resolves catch-alls inside the normal verification.

More expensive per usable address

10,000 verifications cost $25 on DeBounce and $19.50 on WizLeads, and DeBounce keeps 670 of every 1,000 addresses to our 852. Per address you can actually mail, that is $0.0037 against $0.0023.

No Secure Email Gateway detection

No gateway-layer identification is published. Addresses behind Proofpoint, Mimecast or Barracuda answer SMTP probes differently than the mailbox behind them, and they are the addresses most often misjudged.

Why WizLeads is the best DeBounce alternative for email verification

182 more usable addresses per 1,000

WizLeads kept 852 of 1,000 against DeBounce's 670. Both are safe to send; the difference is that a third of your file survives one process and not the other.

Catch-all resolution

A proprietary catch-all verification method returns a concrete valid or invalid verdict on catch-all domains, instead of parking them in a "risky" bucket you can never confidently send to.

SEG detection

Every address is tagged with its mailbox provider and any Secure Email Gateway in front of it — Proofpoint, Barracuda, Mimecast, Appriver, Sophos and more. Gateways are where most verifiers produce false positives.

Catch-all included, not surcharged

Catch-all resolution runs inside the standard verification at the standard rate. DeBounce charges 10 credits for a catch-all check against 1 for a normal one, so the hardest addresses are also the most expensive.

4 areas where WizLeads dominates DeBounce

WizLeads

852 addresses approved, 5 bounced. Safe to send, and 85% of the file survives verification.

670 approved and a single bounce — a 0.1% rate, genuinely better than our 0.60%. It was reached by rejecting 330 addresses, a third of the list.

WizLeads

148 of 1,000 rejected. Catch-all domains are resolved to a verdict rather than discarded, which is where most of the difference sits.

330 of 1,000 rejected, more than twice WizLeads' 148. On a 10,000-email file that should be roughly 3,300 addresses removed against about 1,500.

WizLeads

Catch-all resolution runs inside the standard verification pass at the standard credit rate. There is no premium for the addresses that are hardest to judge.

DeBounce prices standard validation at 1 credit and catch-all validation at 10 credits per check. The addresses most common on B2B lists are billed at ten times the base rate.

WizLeads

Returns the mailbox provider and any Secure Email Gateway in front of it on every row, so corporate domains behind Proofpoint or Mimecast are visible before you send.

No gateway-layer identification is published, so a SEG-protected address is indistinguishable from an ordinary one in the export.

We tested DeBounce and 5 other verifiers on the same 1,000 emails

Every verifier received the same 1,000 Apollo-sourced B2B addresses on the same day. We then mailed every address each one approved and counted the real bounces. Full methodology in the Email Verification Benchmark 2026.

DeBounce is inexpensive per check. The cost is in what it discards.
WizLeads verification costs 0.5 credits an address, so ten thousand checks draw 5,000 credits. The Freelancer plan is $39 a month for 10,000 credits, which puts the job at $19.50.
The same 10,000 verifications cost $25 on DeBounce, $0.0025 a check. Standard validation costs 1 credit and catch-all validation costs 10, and catch-all domains are common on B2B lists.
Then price the output. The same 1,000 emails produced 852 mailable addresses through WizLeads and 670 through DeBounce. Whatever the per-check rate, a third of the file did not survive.

Where DeBounce is better

A lower bounce rate than ours. DeBounce recorded 0.1% — one bounce across 670 approved addresses — which is better than the 0.60% WizLeads returned on the same list. If a near-zero bounce rate is the single number your deliverability process is judged on, DeBounce beat us on it.

Cheaper at the top of its ladder. The lowest verification rate WizLeads publishes is $0.0006 an address, on the Kingpin quarterly plan at $1,199 for 1,000,000 credits. DeBounce's 5,000,000-credit pack works out to about $0.00044 a standard check ($2,200), below that floor — though catch-all validations draw 10 credits each, which narrows the gap on B2B files. If you are cleaning several million addresses a year, it is worth a call with our team first, because we price custom plans at that volume rather than selling off the published tiers.

Frequently asked questions

On our 1,000-email benchmark — Apollo-sourced B2B addresses, six verifiers, same day, April 2026 — DeBounce approved 670 addresses and only one bounced, a 0.1% bounce rate. That is better than the 0.60% WizLeads returned. It reached it by rejecting 330 addresses to WizLeads' 148.

Because a bounce rate only describes the addresses a verifier approved. DeBounce approved 670 of 1,000 and WizLeads approved 852. Both pools are safe to send to; one is 27% larger. The question is whether you want the cleanest possible list or the largest safe list, and most cold outreach is constrained by reachable contacts rather than by bounce rate alone.

DeBounce is pay-as-you-go: 10,000 verifications cost $25, about $0.0025 a check, and credits never expire. Standard validation is 1 credit; catch-all validation is 10. WizLeads runs the same 10,000 verifications for $19.50 on the Freelancer plan, with catch-all resolution included at the standard rate.

Catch-all domains accept any address at the SMTP layer, so deciding whether a specific mailbox exists takes more work. DeBounce prices that work at 10 credits per check against 1 for a standard validation. On B2B lists, where catch-all domains are common, the addresses you most need resolved are the ones billed at ten times the rate. WizLeads resolves them inside the normal verification.

No gateway-layer identification is published. Proofpoint, Barracuda, Mimecast, Appriver and Sophos answer SMTP probes differently than the mailbox behind them, which is where false verdicts on corporate domains come from. WizLeads tags these and other SEGs on every row.

For keeping your list mailable, yes: 852 addresses kept against 670 on the same file, catch-all resolution at the standard rate rather than 10 credits, and SEG detection. DeBounce is the better fit if you want the absolute lowest bounce rate and can afford to lose a third of the file, or if you clean several million addresses a year at the top of its credit ladder.

Yes. Both accept uploaded lists, and both expose an API. WizLeads' verify-email endpoint slots into a Clay, n8n, Zapier or Make waterfall as an HTTP step; the REST API is documented at wizleads.io/api.
