Melissa

Overview

Melissa is a contact-data quality specialist that verifies, standardises and enriches customer records. Its tools cover US and international address verification, phone, email and name verification, matching and deduplication, profiling, generalised and batch address cleansing, and identity verification, delivered through apps and APIs, the Listware online service and its Unison data quality platform.^[18] Melissa also provides connectors for platforms such as Microsoft SQL Server and Talend, so its verification can run inside existing ETL processes.^[18] Unlike warehouse observability tools, which detect anomalies in data pipelines, Melissa corrects the content of individual records, which matters for direct marketing, e-commerce delivery, customer onboarding and compliance. Online services are sold through credits and subscriptions.^[18] Its scope is narrower than general-purpose data quality platforms: it focuses on people, addresses and businesses rather than arbitrary datasets.
