What Byteplant Email Validator is
Byteplant Email Validator is a paid email verification service with free credits, offering real-time API and batch checking through web and API access. It identifies invalid, disposable, fake, or mistyped addresses using DNS and MX records, SMTP availability, mailbox existence, misspelled domains, catch-all behavior, temporary unavailability, and greylisting. Byteplant says validation does not send an email to the recipient. The Bulk API accepts up to 100,000 addresses per request, while the documented default rate limit is 100 requests in 300 seconds. Integrations include WordPress, Drupal, Typo3, Joomla, Zapier, and CRM or database workflows; ready-made plugins are listed for WordPress, Drupal, jQuery, and Node.js. Code examples cover JavaScript, PHP, Java, C#, and VB.NET. The pricing page offers 1,000 free verifications without a credit card. Paid choices include monthly subscription credits and one-time pay-as-you-go credits, with credits that do not expire.
