Maintaining a current and validated email list is essential for the success of any online business. Nevertheless, simply gathering email addresses does not ensure that they are all legitimate and operational. Studies in the field indicate that around 20-30% of gathered emails may be incorrect, inaccessible, or inactive. Employing such an unconfirmed list for email campaigns leads to bounced emails, harm to sender credibility, and financial setbacks. Hence, verifying emails before dispatching any newsletters or promotional content has become indispensable in today’s business environment.
