Email Verifier - PHP Library

Verify email addresses in real time. Check deliverability, detect disposable and catch-all domains, and clean your email lists before sending.

Powered by Enrow -- real-time SMTP-level verification with high accuracy on catch-all domains.

Installation

composer require enrow/email-verifier

Requires PHP 8.1+ and Guzzle 7.

Simple Usage

use EmailVerifier\EmailVerifier;

$verification = EmailVerifier::verify('your_api_key', [
    'email' => 'tcook@apple.com',
]);

$result = EmailVerifier::get('your_api_key', $verification['id']);

echo $result['email'];         // tcook@apple.com
echo $result['qualification']; // valid

verify() returns a verification ID. The verification runs asynchronously -- call get() to retrieve the result once it's ready. You can also pass a webhook URL to get notified automatically.

Bulk verification

use EmailVerifier\EmailVerifier;

$batch = EmailVerifier::verifyBulk('your_api_key', [
    'verifications' => [
        ['email' => 'tcook@apple.com'],
        ['email' => 'satya@microsoft.com'],
        ['email' => 'jensen@nvidia.com'],
    ],
]);

// $batch['batchId'], $batch['total'], $batch['status']

$results = EmailVerifier::getBulk('your_api_key', $batch['batchId']);
// $results['results'] -- array of verification results

Up to 5,000 verifications per batch. Pass a webhook URL to get notified when the batch completes.

Error handling

try {
    EmailVerifier::verify('bad_key', [
        'email' => 'test@test.com',
    ]);
} catch (\RuntimeException $e) {
    // $e->getMessage() contains the API error description
    // Common errors:
    // - "Invalid or missing API key" (401)
    // - "Your credit balance is insufficient." (402)
    // - "Rate limit exceeded" (429)
}
