Case Study

Fort Lauderdale, Florida-based Citrix Systems, Inc. is the global leader in access infrastructure solutions. Citrix software enables people in businesses, government agencies, and educational institutions to securely access applications and information from anywhere, anytime, using any device, over any connection. Citrix customers include 100 percent of the Fortune 100 companies, 99 percent of the Fortune 500, and 92 percent of the Fortune Global 500.


The Challenge

Citrix Systems wanted to bring its contact database up-to-date in order to proactively communicate with its customers via email and increase brand awareness.

To do this, Citrix needed to:

  • Acquire email addresses for all customer, prospect, and partner contacts in its global database,

  • Identify defunct customer companies or those no longer using Citrix products

  • Identify outdated contacts, and reduce its direct mail costs. 



Citrix used TowerData’s B2B Email Appending service to obtain a permission-based list of business email addresses — not personal emails — for contacts spread out across North America, Europe and the Asia Pacific region.


TowerData appended email addresses to 93% of Citrix appendable contacts, leading to over 850 new business leads and an estimated savings of more than $100,000 per year in direct mail costs.

Product, marketing and customer care teams were able to reach more existing clients, and email bounce rates were reduced to a low of 3% from a high of 35%.
