EVA (verifications.email) and NeverBounce both verify whether an email address can receive mail before you send to it. NeverBounce, owned by ZoomInfo, is the established choice, with more than 80 platform integrations and a Growth plan that bundles verification with lead data for sales teams. EVA is a developer-focused verification API with lower prices, a larger free tier, and a self-hosted option. The sharpest differences are price, credit expiry, and hosting. NeverBounce's published pay-as-you-go rate is $8 per 1,000 credits, while EVA's credit packs run from $5.00 down to $1.20 per 1,000 and its Pro plan works out to $1.63 per 1,000. NeverBounce credits expire 12 months after purchase; EVA credits never expire. NeverBounce offers no self-hosted deployment; EVA sells a one-time self-hosted license from $4,995. EVA also gives every account 300 free verifications per month and never charges for unknown results.
NeverBounce's published pricing as of August 2026 lists a flat pay-as-you-go rate of $8 per 1,000 credits, a Growth subscription at $49 per month covering up to 10,000 emails, and custom Enterprise pricing for teams verifying 250,000 or more per month. Pay-as-you-go credits expire 12 months after purchase. EVA prices are the live rates from the EVA pricing page: subscriptions from $19 per month and credit packs from $5, and credits never expire.
| Volume | NeverBounce | EVA subscription | EVA credit packs |
|---|---|---|---|
| 1,000 emails | $8 pay as you go ($8.00 per 1,000) | Starter $19/mo includes 5,000 ($3.80 per 1,000) | $5 (1K pack, $5.00 per 1,000) |
| 10,000 emails | $80 pay as you go, or Growth $49/mo (up to 10,000) | Pro $49/mo includes 30,000 ($1.63 per 1,000) | $40 (two 5K packs, $4.00 per 1,000) |
| 100,000 emails | $800 at the published $8 per 1,000 rate | Business $149/mo includes 100,000 ($1.49 per 1,000) | $200 (100K pack, $2.00 per 1,000) |
| 1,000,000 emails | Custom Enterprise pricing (250K+/mo) | Enterprise, custom pricing | $1,200 (1M pack, $1.20 per 1,000) |

Three things stand out: credits that never expire, a recurring free tier, and a self-hosted license. EVA also publishes exactly what each verification runs: 28 checks per address, with dedicated SMTP strategies for Google, Microsoft, Yahoo, Apple, ProtonMail, Zoho, and other major providers, plus catch-all scoring and domain-level deliverability grading. NeverBounce's strength runs the other way: its ZoomInfo ownership means deep integration with sales tooling that EVA does not attempt.
| Feature | EVA | NeverBounce |
|---|---|---|
| Checks per email | 28 | Not published |
| Provider-specific SMTP verification (Google, Microsoft, Yahoo, Apple) | Yes | Not published |
| Catch-all handling | Scored, with M365 and Yahoo resolution | Flags accept-all domains |
| Unknown results charged | Never | Not published |
| Credits expire | Never | After 12 months (per its pricing page) |
| Free tier | 300/mo | Test credits at signup |
| GDPR / DPA | Yes, DPA available | Advertises GDPR compliance |
| Self-hosted option | Yes, one-time license from $4,995 | No |
| SDKs | JavaScript and Python | Yes, multiple languages |
| Bulk upload | 50,000 emails per upload | Yes |
No. NeverBounce is available only as a cloud service, so every verification is billed per credit and every address you check passes through its infrastructure. EVA offers both: the same cloud API, and a self-hosted deployment license from $4,995 one-time. The self-hosted version runs the full 28-check engine on your own servers with Docker, unlimited volume, and zero per-email cost. At NeverBounce's published $8 per 1,000 rate, 625,000 verifications cost more than the entire EVA license, once.
An honest comparison cuts both ways. NeverBounce is the stronger pick if:
Yes, at the published rates. NeverBounce's pay-as-you-go price is $8 per 1,000 credits (published pricing as of August 2026). EVA's credit packs run from $5.00 per 1,000 down to $1.20 per 1,000 at one million credits, and EVA's Pro subscription works out to $1.63 per 1,000.
Yes. NeverBounce's pricing page states that pay-as-you-go credits expire 12 months after purchase (published pricing as of August 2026). EVA credits never expire; a pack you buy today is still usable years from now.
NeverBounce offers free list analysis and test credits at signup, but no recurring free monthly allowance is listed on its pricing page. EVA includes 300 free verifications every month on every account, with the full 28-check suite.
No. NeverBounce is a cloud-only service. EVA sells a self-hosted deployment license from $4,995 one-time, which runs the same 28-check engine on your own servers with unlimited verifications and no per-email cost.
Export your list from NeverBounce as CSV, create a free EVA account with 300 verifications per month, and upload the file or call the API. EVA accepts up to 50,000 emails per bulk upload and ships JavaScript and Python SDKs, so most API migrations are a small code change.
Run the same list through both. 300 free verifications every month, no credit card, and unknowns are never charged.
