Looking for the best Prospeo alternative?

On our 1,000-lead benchmark — identical input to seven finders, one neutral SMTP verifier, April 2026 — Prospeo returned 270 emails of which 259 passed verification, a 25.9% find rate and the lowest net output in the test. WizLeads returned 670, all of which passed.

No. Prospeo states that credits do not roll over, on the free plan or on any paid tier, so the allowance resets at the end of each billing cycle whether you used it or not. WizLeads credits roll over one month on monthly plans and three months on quarterly plans while the subscription is active.

Prospeo bills one credit per verified email, and credits do not roll over, so a 10,000-email job needs the $249 Pro plan and its 15,000 credits. At $0.0166 per credit the job itself costs $166. WizLeads delivers 10,000 found emails for $89.

Yes, and it renews: 100 credits every month, though those credits do not roll over either. WizLeads offers a free one-time trial of 500 credits including enrichment and verification, enough to enrich a real 100-lead list end to end.

Individual lookups do not. Prospeo's own pricing states an export costs one credit per email found and nothing when no email is found. Bulk imports are reported to work differently: reviewers describe a credit consumed for every row regardless of outcome, with one G2 reviewer importing a 1,000-contact Sales Navigator list, receiving 45 matches, and being charged all 1,000 credits. WizLeads charges on find at any volume, whether the job runs as one row or ten thousand.

Not to a verdict. Prospeo describes a five-step validation process that includes catch-all handling, but those rows come back labelled catch-all rather than valid or invalid, which leaves you deciding whether to risk them. A catch-all domain accepts any address at the server, so a standard SMTP probe cannot tell a real mailbox from an invented one. WizLeads resolves catch-all addresses to valid or invalid in the same pass as enrichment, so they arrive already sorted.

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

No. Prospeo publishes no gateway-layer identification. Approximately 15-20% of B2B leads sit behind Proofpoint, Mimecast, Barracuda and similar gateways, which answer SMTP probes differently than the real mailbox. WizLeads tags the provider and gateway on every row.

For volume enrichment, yes on the measures we tested: 670 usable emails per 1,000 leads against 259, about half the cost per found email, credits that roll over instead of expiring, Secure Email Gateway tagging, and account-less Sales Navigator scraping. Prospeo's advantages are a recurring monthly free tier, a lower $49 entry plan, and firmographic company data.
