About
Founded in 2004, Glasgow-based Johnston Mailing processes millions of mail items each year, supporting clients across varied sectors including travel, charity and financial services. With a lean core team of 15 and rapid scalability during peak periods, the business delivers high-volume campaigns with precision.
The Challenges
Data quality is a fundamental part of Johnston Mailing’s services, and many clients underestimate the condition of their data.
To minimise wasted costs, compliance risks and reputational damage, they needed to suppress deceased and gone aways records, acquire movers’ new addresses and correct records with PAF addressing for optimum deliverability.
Slow, Cumbersome Processes
Data audits took too long and interfaces were difficult to use, creating friction for internal teams when adjusting cleansing parameters to client requirements.
Incomplete Data Management
Clients frequently underestimated the condition of their data, leaving deceased and gone-away records unsuppressed, movers' addresses unupdated, and PAF addressing uncorrected.
Wasted Costs and Reputational Damage
Poor data quality exposed clients to unnecessary spend, compliance risks, and damage to their brand through undeliverable or inappropriately targeted mailings.
Our Solution
Johnston Mailing adopted Data8 Online data cleansing platform to audit and cleanse customer data quickly and accurately.
