Datanyze vs No2Bounce: They Solve Different Problems
Comparing Datanyze to No2Bounce is like comparing a fishing rod to a cooler. One catches the fish, the other checks if it's still fresh. Datanyze finds contact data. No2Bounce verifies email addresses. They don't compete - they complement each other.
The real question is whether you need two tools at all.
30-Second Verdict
Use Datanyze if you need a lightweight Chrome extension to pull emails and phone numbers from professional profiles on a budget.
Use No2Bounce if you already have a contact list and need to scrub it before sending.
What Each Tool Actually Does
Datanyze: Contact Sourcing
Part of ZoomInfo, Datanyze is a Chrome extension that reveals emails, direct dials, and mobile numbers while you browse professional profiles and company websites. Its database covers 120M contacts, 84M email addresses, and 48M direct dials. On G2, it holds a 4.1/5 rating across 446 reviews - users consistently praise the in-browser workflow.
A user on r/b2b_sales called it the "best bang for the buck." The recurring complaints? Customer support is slow, and the credit-based model feels restrictive once you start scaling. That said, for small teams doing manual prospecting, the simplicity is hard to beat - you don't need to learn a complex platform to start pulling contacts.
No2Bounce: Email Verification
No2Bounce isn't a contact database. It's an AI-powered email verification platform that validates emails you already have, including catch-all validation and spam-trap checks. The company has processed 500M+ emails with a 90-97% accuracy rate.
Where No2Bounce stands out is catch-all domain handling. Trustpilot reviewers give it 4.5/5 across 26 reviews, highlighting affordability and speed. It also offers a REST API for real-time verification, bulk validation, and AI-based email scoring - though G2 reviews note it needs more CRM integrations. You get 100 free credits to test before committing.
Datanyze finds contacts but doesn't verify them. No2Bounce verifies but doesn't find them. Prospeo does both - 300M+ profiles with 98% email accuracy, built-in 5-step verification, and a 7-day data refresh cycle. No CSV exports, no second tool, no coordination tax.
Get verified contacts in one step for $0.01 each.

Per-unit cost tells the real story. Datanyze's $55/month plan includes 160 credits - about $0.34 per contact reveal. There's also a $29/month tier with 80 credits at roughly $0.36 each. No2Bounce costs about $0.0017 per verification at the 10k monthly tier. They're in completely different pricing universes because they do completely different things.
For context on verification accuracy: a Hunter benchmark testing 15 verifiers against 3,000 real business emails found top tools hitting 68-70% accuracy. No2Bounce wasn't included in that specific test.
The Real Cost of Using Both
Here's where the two-tool workflow breaks down.
Say you reveal 160 contacts on Datanyze's $55/month plan includes 160 credits. Then you run those 160 emails through No2Bounce: about $0.27. Total: ~$55.27/month for 160 verified contacts. Sounds manageable on paper.
We've run this kind of stacked workflow ourselves, and the friction adds up fast. Contact data decays 22.5-30% annually, which means a chunk of those reveals are already stale before you send the first email. You're paying for sourcing, then paying again for verification, and still eating bad data. The coordination tax alone - exporting CSVs, uploading to a separate tool, cross-referencing results - eats more time than most teams realize.
Look, if your outbound volume is under 200 contacts a month, you almost certainly don't need two separate tools.
Which Should You Pick?
You already have a list that needs cleaning. No2Bounce is a solid, affordable verifier - especially for catch-all domains. Start with 100 free credits, then move to the $17/month plan if the results hold up.
You need to find contacts on a tight budget. Datanyze's Chrome extension is simple and the free tier gives you 10 reveals to test. The $55/month plan gets you 160. Just know you'll want to verify those emails somewhere before sending.
For most outbound teams, that's the smarter path.
The Datanyze + No2Bounce stack costs ~$0.35 per verified contact. Prospeo's paid plans drop that to $0.01 - 35x cheaper with higher accuracy. 75 free verified emails per month, no contract, no sales call required.
Stop paying twice for what one platform handles better.
