One API call runs 28 checks on any address in under a second, so invalid, disposable, and risky emails never make it onto your list. Available as a cloud API, or self-hosted on your own infrastructure with unlimited volume.
Live result from the production engine, no signup needed.
No credit card, and you are never billed for an unknown result.
Three steps from a raw list to a clean one. No email is ever delivered to the addresses you check.
One REST call, an SDK on npm or PyPI, or a CSV or Excel upload in the dashboard. Nothing to install on your side.
Syntax, DNS and MX, a live SMTP conversation that stops before any message is sent, provider-specific verification for Gmail, Microsoft 365, Yahoo and others, plus disposable, role, catch-all, spam trap and blacklist screening. Under a second per address.
Every address comes back safe, risky, invalid, or unknown with a 0 to 100 score. Keep the valid ones, review the risky ones, drop the rest. Unknown results are never billed.
Same engine, same 28 checks, same pricing. Pick the shape that fits your workflow.
Upload a CSV or Excel file of up to 50,000 addresses, watch it process in the dashboard, and download the cleaned list. Unknowns can be re-run once the mail server settles.
Bulk verification →One REST call per address, back in under a second, with official SDKs on npm and PyPI. Validate signups and form fills before a bad address ever reaches your database.
API reference →The exact engine behind the cloud API, shipped as Docker images for your own infrastructure. Unlimited verifications for a flat $4,995 a year, updates and support included.
Self-hosted license →Pick your language on the left. The response on the right is what every call returns. Full reference in the API docs.

}Four things that are true on every plan, starting with the free one.
Gmail, Microsoft 365, Yahoo, Apple, ProtonMail, Zoho and Mail.ru each get their own strategy instead of one generic SMTP probe. That is how catch-all and accept-all domains still come back with a real answer.
If a mail server times out or answers ambiguously, the result is marked unknown and costs nothing. You only pay for verdicts you can act on.
$1 per 1,000 on every subscription and $1.20 per 1,000 pay-as-you-go. No feature gates between tiers, no expiring credits, no surprise volume bands.
The cloud service and the self-hosted license share one engine. When policy says data cannot leave your network, the same verification runs inside it.
Bounces tell every mailbox provider that you don't know who is on your list. And the penalty lands on your good emails too.
is all it takes
Deliverability guidance from major ESPs, including Mailchimp and Validity, puts the danger zone at a 2 to 3% bounce rate. Cross it and mailbox providers start quietly routing you to spam. Even the addresses that are real stop seeing you.
of your list dies each year
HubSpot's database decay research puts natural list decay at roughly 22.5% per year. People change jobs and abandon inboxes on their own, so the list that performed last year is a bounce factory today.
to recover a burned domain
One bad campaign can wreck a domain's reputation. Rebuilding it takes weeks of careful warm-up. Checking an address first costs a fraction of a cent.
EVA catches dead, disposable, and trap addresses before they touch your reputation.
An email verification API checks whether an address can actually receive mail before you rely on it. verifications.email runs 28 checks on every address in a single call: syntax validation, DNS and MX record lookups, a live SMTP conversation with the recipient's mail server that stops before any message is sent, and provider-specific verification for Google, Microsoft, Yahoo, Apple, ProtonMail, Zoho, and Mail.ru accounts. It also flags disposable addresses, role accounts like info@ and admin@, catch-all domains with a confidence score, likely spam traps, and domains listed on any of 10 blacklist zones. Each result returns in under a second with a 0 to 100 score and a risk classification of safe, risky, invalid, or unknown. Unknown results are never billed. Teams use it to clean marketing lists, validate signups in real time, and protect sender reputation.
Complete verification on every plan. No feature gates. Pay for volume, not capabilities.

verifications.email (EVA) is an email verification API that tells you whether an address can actually receive mail before you rely on it. One API call runs 28 checks, from syntax and DNS through a live SMTP probe and provider-specific verification, and returns a 0 to 100 score with a risk classification in under a second. It is built for marketers cleaning lists, SaaS teams validating signups, and developers embedding verification. Pricing starts free at 300 verifications per month, and the engine can also be self-hosted under a flat annual license.
EVA opens an SMTP conversation with the recipient's mail server and stops before any message is sent. The server's responses reveal whether the mailbox exists. On top of that, EVA uses provider-specific strategies for major providers, because Gmail, Microsoft 365, and Yahoo each answer differently. No email ever lands in anyone's inbox.
EVA achieves 99% verification accuracy using provider-specific strategies rather than a single generic SMTP probe. When a definitive answer is not possible, the result is marked unknown and is never charged.
EVA's free plan includes 300 verifications per month. Paid plans cost $1 per 1,000 verifications on every tier, from $20/month for 20,000 to $150/month for 150,000. Pay-as-you-go credits are a flat $1.20 per 1,000, from 25,000 credits for $30. Credits never expire. A self-hosted license at $4,995/yr removes per-email costs entirely.
Yes. The same engine behind the cloud API is available under an annual deployment license at $4,995/yr with unlimited verifications on your own infrastructure, deployed with Docker, all updates and support included. An OEM source license is available for embedding verification in your own product. See the self-hosted guide for how the options compare.
No credit card. No strings attached.
