verifi.email figures assume you use the included monthly allowance; additional validations cost $4 per 1,000. ZeroBounce uses one credit per email validation; scoring is a separate credit-consuming service. ZeroBounce says unknown validation results and duplicate removal are not charged.

ZeroBounce also offers ONE subscriptions from $99/month with 10,000 validation/scoring credits and other tools, plus annual and subscriber discounts. Those offers are not used in the pay-as-you-go table. Prices exclude taxes, promotions, and negotiated terms. Check checkout and credit-expiration terms before buying.

Where ZeroBounce is better

Choose ZeroBounce for a broader deliverability suite

It also offers asynchronous file processing and detailed status codes. Availability and credit costs depend on the service and plan.

Don’t need an entire deliverability suite?

verifi.email provides fast, affordable email syntax, domain and disposable-address checks through a straightforward API. Starting at $9/month for 5,000 validations.

Switching is not drop-in: replace the endpoint and credentials, map the response fields, and test your accept/reject rules on representative addresses. See our features or ask us about your use case.

Try the verifi.email API

Create your free account, copy your API key from the dashboard, and replace the placeholder below. These examples use real routes and supported request formats. They require your own key and available credits. Replace the sample addresses with those you want to check.

Validate one address with cURL

export VERIFI_API_KEY='replace-with-your-api-key'
curl --fail-with-body --get 'https://api.verifi.email/check' \
  --data-urlencode "token=$VERIFI_API_KEY" \
  --data-urlencode '[email protected]' \
  --header 'Accept: application/json'

Validate a batch with cURL

After exporting VERIFI_API_KEY above, send comma-separated addresses with safely encoded query parameters:

curl --fail-with-body --get 'https://api.verifi.email/v1/bulk/check' \
  --header 'Accept: application/json' \
  --data-urlencode "token=$VERIFI_API_KEY" \
  --data-urlencode '[email protected],invalid-email'

Use JavaScript on your server

// Node.js 18+; run on your server, never expose your API key in a browser.
const token = process.env.VERIFI_API_KEY;
if (!token) throw new Error('Set VERIFI_API_KEY first');

const url = new URL('https://api.verifi.email/check');
url.search = new URLSearchParams({ token, email: '[email protected]' }).toString();
const response = await fetch(url, { signal: AbortSignal.timeout(30000) });
if (!response.ok) throw new Error(`Validation failed: HTTP ${response.status}`);
const result = await response.json();
console.log(result.valid, result.details);

Keep keys on your server and out of browser code, public repositories, and logs. Handle non-2xx responses rather than treating them as an invalid-address result. Read the full API documentation for more examples and domain health checks.

Start small. Test with your own addresses.
