Why an email verification service ?

Did you know that...?

  • ~20% of email registrations contain typos, syntax, domain and other errors
  • Only 28% of all messages sent worldwide ever reach the inbox
  • Having just 1% of your list bad can drop your deliverability by over 10%!

"AlgoCheck is the best way to eliminate hard bounces, reduce spam complaints and minimize fraud" - Henry

Based on highly accurate algorithms

Over the past few year, we have developed many highly accurate algorithms to determine if an email address is valid or not, including :

  • Syntax verification & typo check
  • Free provider check (detect free email services such as Gmail and Yahoo!)
  • Disposable email address detection (mailinator,...)
  • Real-time SMTP & MX record look-up
  • Quality Score: a score that reflects the quality and deliverability of each email address
  • Data protection: Your list is transmitted, validated and maintained through secure means
