In the competitive landscape of email marketing, achieving and sustaining a 90%+ validation rate isn’t just a goal – it’s a necessity. High data quality directly impacts deliverability, sender reputation, and ultimately, ROI. This article explores real-world case studies demonstrating how organizations have dramatically improved their email list health through robust data hygiene practices. We’ll cover strategies, tools, and best practices for achieving exceptional results.
