Case Study: Darwinbox doubles SQL reply rate with Hunter.io

Darwinbox Doubled SQL Reply Rate With Hunter

Darwinbox, an HR technology platform serving over 900 organizations, needed a reliable solution to improve their email outreach after their previous verification tool resulted in a high bounce rate with many unclear "unknown" and "accept-all" addresses. Their sales and marketing teams required accurate email-finding and verification from a vendor like Hunter.io to better connect with HR professionals and executives.

By implementing Hunter.io for email verification, the team saw a 15-20% improvement in accurately defining email validity. This superior data quality directly led to a dramatic increase in their outreach success. Darwinbox reported that their response rate from sales-qualified leads doubled from 6% to 12% because they had the right email addresses at the right time thanks to Hunter.io.
