Antideo vs Wiza: You're Probably Comparing the Wrong Tools
If you're weighing Antideo against Wiza, you're likely conflating two different categories. We've seen teams waste months trying to make these work as substitutes for each other. Antideo validates emails. Wiza finds them. One is a validation API for cleaning inbound data; the other is a prospecting tool for building outbound lists from professional profiles.
30-second verdict: Use Antideo if you're scrubbing form submissions and blocking spam. Use Wiza if you need to export verified contacts for outbound sequences. If you need prospecting and verification without stitching tools together, skip both and try Prospeo. Email lists decay roughly 28% per year, so whichever direction you go, move fast.
What Each Tool Actually Does
Antideo
Antideo is a validation API, full stop. You send it an email address, IP, or phone number, and it tells you whether it's legit - checking disposable domains, spam traps, free providers, syntax issues, and IP reputation. If you're comparing verifiers, see our breakdown of email verification options.
There's a WordPress plugin that validates form fields in real time; one reviewer reported blocking over 100,000 spam submissions in three months. The entire product is plumbing for developers and marketing ops teams. You won't find a contact database or Chrome extension here. If you're looking for new leads, Antideo can't help you.

Wiza
Wiza is a B2B prospecting tool built around a Chrome extension (rated 4.8/5 on their site) that exports contacts from professional profiles. It covers 850M+ prospects with 40+ data points, includes built-in email verification, and exports to CSV or syncs to CRMs. If you're building outbound lists, these sales prospecting techniques help you avoid low-intent scraping.
Here's the thing: Wiza depends entirely on a separate professional network subscription to function. It doesn't maintain a standalone database. Accuracy drops noticeably outside North America, and scraping professional profiles can trigger account restrictions - something the r/sales community flags regularly. Across 1,142 G2 reviews (4.5/5), 157 reviewers call it expensive and 127 cite limited credits.
Feature Comparison

Antideo's G2 score looks impressive, but three reviews isn't a sample size - it's a rounding error. If you're trying to protect inbox placement after list cleaning, use an email deliverability guide to fix the upstream issues too.
Why pay $300+/month for Wiza plus a network subscription when Prospeo combines prospecting and verification natively? 300M+ profiles, 98% email accuracy, 7-day data refresh - no third-party dependencies.

Pricing Breakdown for 2026
Antideo (approximate USD conversions - verify on their site for exact figures):
| Plan | Price | Rate Limit |
|---|---|---|
| Free | $0/mo | 10 req/hour |
| Plan 1 | ~$5/mo | 50 req/hour |
| Plan 2 | ~$10/mo | 100 req/hour |
| Plan 3 | ~$20/mo | 300 req/hour |
| Plan 4 | ~$50/mo | 1,000 req/hour |
| Plan 5 | ~$80/mo | 2,000 req/hour |
Wiza:
| Plan | Monthly | Annual |
|---|---|---|
| Free | $0 (20 emails/mo) | - |
| Starter | $49/user/mo (100 emails + 100 phone numbers) | - |
| $99/user/mo (500 emails) | $83/user/mo | |
| Email + Phone | $199/user/mo | $166/user/mo |
Overages hit hard: $0.15 per extra email, $0.35 per phone number. And the number on the pricing page isn't the real number - Wiza requires a separate professional network subscription ($99-$149/mo) to function at all. That puts your actual monthly cost at $265-$315 for the Email + Phone tier before overages even kick in.
Let's be honest: if you're paying $300+/month for a prospecting tool that still needs a third-party subscription to work, you're subsidizing someone else's infrastructure problem. If you're evaluating alternatives, start with a shortlist of outbound lead generation tools and compare total cost per verified contact.
Which One Should You Pick?
Use Antideo if your marketing team is drowning in fake form submissions. You need a lightweight validation API under $80/mo, and you don't need to find new contacts - you just need to clean the ones you already have. If you're also fighting bounces, track your email bounce rate and remove risky segments early.
Use Wiza if you're an SDR who needs verified emails for an outbound campaign this week. Just know that in our experience, real-world deliverability runs closer to 90-95%, not the 99%+ on the marketing page. Phone accuracy sits around 55-65%. Wiza competes with Apollo, Lusha, and Seamless.AI in this category - all worth evaluating before you commit. If you're building an SDR stack, see our guide to the best SDR tools.
Skip both if you need prospecting and verification without stitching two tools and two subscriptions together. Prospeo handles both natively - 300M+ profiles, 98% email accuracy, 143M+ verified emails, 125M+ verified mobiles, with data refreshing every seven days. Its proprietary email-finding infrastructure means no dependency on third-party network subscriptions. Pricing starts free (75 emails/month) and scales at roughly $0.01 per email, a fraction of Wiza's all-in cost. Teams using Prospeo report bounce rates under 4% and 30% mobile pickup rates - numbers that hold across regions, not just North America. If you want a broader benchmark set, compare against sales prospecting databases before you lock in.
Antideo validates what you have. Wiza finds contacts but needs a separate subscription to work. Prospeo gives you 143M+ verified emails and 125M+ verified mobiles with built-in 5-step verification - no stitching required.
Replace two tools and two bills with one platform that actually works globally.
FAQ
Are Antideo and Wiza competitors?
No. Antideo validates existing emails via API. Wiza finds new contacts from professional profiles. Comparing them is like comparing a spell-checker to a word processor - they solve fundamentally different problems in the sales and marketing stack.
Can I use Antideo and Wiza together?
You could export contacts from Wiza and re-verify through Antideo's API, but running two tools adds cost and complexity. A single platform that combines prospecting with built-in multi-step verification at roughly $0.01 per email eliminates that overhead entirely.
What's the cheapest way to get verified B2B emails in 2026?
Prospeo's free tier gives you 75 verified emails per month with no credit card required - the most generous free option that includes both finding and verifying contacts. Antideo's free tier handles 10 validation requests per hour but can't find contacts. Wiza's free plan caps at 20 emails monthly and still requires a paid network subscription to do anything useful.
