Every bounce tells Gmail and Outlook you don't know your own list. One API call runs 28 checks on every address before you send: syntax, DNS, provider-level SMTP, disposable, catch-all, blacklists. Results in under a second.
Verification that pays for itself. Cloud from $0.001/email, or self-host with unlimited volume.
If we can't give you a definitive answer, the check is free.
Bounces are a signal to every mailbox provider that you don't know who you're sending to. 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 send 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 you press send.
An email verification API checks whether an address can actually receive mail before you send to 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 18 blacklist zones. Each result returns in under a second with a 0 to 100 score and a risk classification of valid, invalid, risky, or unknown. Unknown results are never billed. Teams use it to clean marketing lists, validate signups in real time, and protect sender reputation.

verifications.email (EVA) is an email verification API that tells you whether an address can actually receive mail before you send to 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 run from $19/month for 5,000 to $149/month for 100,000 verifications. Pay-as-you-go credit packs start at $5 for 1,000 credits and go down to about $0.001 per email at volume. 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.
