Real-Time Email Validation API & Bulk Email List Cleaning: Improve sender reputation, deliverability and reduce bounce rates with Byteplant’s online email verification API & email list cleaning services.

Email Address Validator

Email is the main point of contact between your business and the customer. Byteplant will help you reach your customers and keep your email sender reputation intact. We offer full end-to-end services for all your email validation needs.

Our Email Validation Services

Email validation increases your delivery rates, reduces hard bounces and improves your sender reputation at the same time.

With our Real-Time Email Verification API and Bulk Email List Cleaning services you can easily clean up existing email lists or verify if an email address entered into a registration form on your website really exists and can receive emails. For each email address you get a detailed validation result with the exact deliverability status.

A clean mailing list is essential to your email marketing success. Your email sender reputation - the number of bounces, spam complaints and spam trap hits caused by your mailings - is responsible in 83% of all cases where email does not reach the inbox.

Email Validator will help you steer clear of unwanted or outdated email addresses, spelling errors and will improve your delivery rates. Save your email marketing budget for existing email addresses.

Which Checks Does Email Validator Perform?

Our Email Validator uses a multi-layer checking process, with every single email going through all of these testing and cleaning steps:

  • Syntax verification (IETF/RFC standard conformance)
  • DNS validation, including MX record lookup
  • Disposable email address detection
  • Misspelled domain detection to prevent Typosquatting
  • SMTP connection and availability checking
  • Temporary unavailability detection
  • Mailbox existence checking
  • Catch-All testing
  • Greylisting detection

During the entire process, we never send any email to the recipient address.
