Comparison criteria
Both tools were tested on the same email list under the same conditions. Here is how we scored them.
1. Provider coverage
We built our test list to mirror real-world inbox distribution. Share figures come from SellCell's breakdown of the most popular email providers by number of users - Gmail, Yahoo, Outlook, iCloud, AOL, and others weighted by how many people actually use them.
Every verifier was run against the same 16-address list - one valid and one invalid mailbox per provider. These are free-email inboxes that most verifiers struggle with; they show up constantly in real lead lists and are where false "risky" or "unknown" flags appear.
| Provider | Valid | Invalid |
|---|---|---|
| Gmail | [email protected] | [email protected] |
| iCloud | [email protected] | [email protected] |
| Outlook | [email protected] | [email protected] |
| Proton | [email protected] | [email protected] |
| GMX | [email protected] | [email protected] |
| Yahoo | [email protected] | [email protected] |
| AOL | [email protected] | [email protected] |
| Zoho | [email protected] | [email protected] |
A verifier only gets full marks if it returns a definitive result for every address above - not just the easy corporate domains. Reported coverage is the percentage of our list each tool could actually verify. When a tool skips Yahoo or AOL entirely, we subtract that provider's share from the score (e.g. 100% - 6.4% Yahoo - 0.7% AOL = 92.9%).
2. Price (100K verifications / month)
Taken directly from each vendor's public pricing page at the time of testing. We quote the monthly cost for 100,000 verifications. No annual discounts or negotiated enterprise rates.
3. Speed
Measured end-to-end on our full test list - from upload to downloadable results. The headline number is always total list time.

NeverBounce performance
neverbounce.com · $450/mo for 100K
NeverBounce handled most of our list well, but Yahoo and AOL addresses were not verified with the same confidence as dedicated provider checks. Effective coverage on our weighted list: 92.9%.
Under 30 seconds on bulk - fast
92.9% provider coverage
Pros
- ✓ Excellent real-time API and form widget
- ✓ Strong ESP integrations (Mailchimp, HubSpot)
- ✓ Well-known brand with solid docs
Cons
- ✗ Expensive at bulk volume
- ✗ Weaker on Yahoo, AOL, and catch-all providers
- ✗ Bulk pricing less competitive than dedicated tools
Summary: NeverBounce is a strong pick for live signup forms. For bulk list cleaning, Wontbounce is faster, cheaper, and more reliable on free providers.
Wontbounce performance
wontbounce.com · $99/mo for 100K

~7 seconds - fastest in the test
100% provider coverage
Pros

Summary: Wontbounce is the better NeverBounce alternative for bulk verification when Yahoo, AOL, and Zoho accuracy matter more than a JavaScript widget.
