Ensuring high-quality email data
Succeeding in their mission to help each client attain success requires Herold to address pressing daily issues, such as bounce rates, email deliverability, and sender reputation. Companies accumulate a large number of customer email addresses over time, some of which may already be inactive or invalid. Large volumes of outdated email addresses can hinder transactional and online marketing efforts, with customers unable to receive invoices, company product communications, and other online content.
Email validation is required to ensure email list quality and must be automated to avoid operational bottlenecks stemming from time-consuming manual validation.
