Email Validation API.
10× cheaper than ZeroBounce.

Pay only for what you use. Stripe charges your card automatically at month end. No setup fee, no monthly minimum.

Each email address passes through five checks sequentially. Results come back as structured JSON with a deliverability score from 0 to 100.

POST a batch of up to 500 emails. Authenticate with Authorization: Bearer YOUR_KEY or X-Api-Key: YOUR_KEY.

# pip install emailval-client
from emailval import EmailValidator

ev      = EmailValidator(api_key="YOUR_API_KEY")
results = ev.validate(["user@company.com", "test@mailinator.com", "bad-address"])

for r in results:
    print(r.email, "→ score", r.score, "| valid:", r.is_valid)

curl -X POST https://api.emailval.net/v1/validate \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"emails":["user@company.com","test@mailinator.com","bad-address"]}'

const r = await fetch("https://api.emailval.net/v1/validate", {
  method:  "POST",
  headers: { "Authorization": "Bearer YOUR_API_KEY", "Content-Type": "application/json" },
  body: JSON.stringify({ emails: ["user@company.com", "test@mailinator.com", "bad-address"] }),
});
(await r.json()).results.forEach(x => console.log(x.email, "→", x.score));
