Private Mailing System

The Client

A Guatemalan financial institution in the credit card industry.

Companies in the credit card industry are subject to tight security and legal standards. However, that does not change the need to communicate with clients through modern and reliable channels. Email campaigns are still one of the most effective ways to reach and engage clients.

The Goal

Develop a private emailing service capable of handling the thousands of emails the client needs to send every month.

At the same time, the service needs to comply with PCI DSS (Payment Card Industry Data Security Standard) and local regulation which imposes a few restrictions on the required system. For example, no external mailing provider could be used.

The Result

A fast, lightweight and cost-effective system to manage Contacts, Email Campaigns and Analytics for email communications. Authentication was delegated to the existing Active Directory domain. The system is capable of delivering up to 18k emails per hour, to srtike an affordable balance between processing cost and delivery speed.
