Case Study: Listrak

Summary
Marketing automation vendor Listrak deploys on average 2.5 million emails per hour per server and sends over a billion emails monthly across more than 1000-plus clients/marketers. On CyberMonday, 2014, Listrak deployed over 4M emails per hour per server. Listrak’s integrated digital marketing platform helps its customers create retail-specific solutions across all touch points. The company’s top 20 marketers average roughly 800K subscribers each.

Listrak previously used a homegrown custom-built MTA as its outbound sending solution. As the sending solution approached the limit of its throughput capacity, management decided they urgently required a solution with much greater ability to scale.

The homegrown solution also lacked specific, highly granular configuration settings for managing diverse sends across Listrak’s growing client base. The company commissioned Port25’s PowerMTA, which drastically simplified creation of complex configuration schemes and empowered Listrak’s deliverability administrators to customize its feature-rich sending platform almost effortlessly. With PowerMTA™, Listrak was able to overcome the delivery challenges that threatened to limit the growth of its sending capacity.

The Infrastructure Challenge
Ten years ago, Listrak had become known as a provider of trusted multi- channel digital marketing solutions. Rapid growth had brought the company visibility as a leading ESP. Now, Listrak needed a robust, scalable messaging platform with a rich feature set that would allow it to manage many times its current volume.

The former system, developed in-house, had anemic reporting features, poor injection rates, and lacked a digital messaging delivery dashboard. It employed a patched-together mix of servers and VB scripts that had served the company reasonably well, but had reached the limits of its viability. The home-grown solution lacked a linear path for maximizing throughput across a growing list of eager marketers who wanted their mail sending capability deployed quickly.

The original VB scripts and Microsoft Exchange servers with IIS built-in SMTP service had proved capable of handling the growing volume thus far, but the IT team realized it would be a major challenge to scale high-volume sends using this method. The IT staff briefly experimented with an array of Unix servers tethered to Sendmail, but this solution, too, was overwhelmed by the scalability issues. Listrak then evaluated the PowerMTA platform for its claimed ability to scale effortlessly and help Listrak’s small IT team author complex configuration settings rapidly and easily.

The Solution
Andrew Wingle, Listrak’s principal delivery strategist, says, “It has met and exceeded our expectations. It was crucial that PowerMTA™ empower the delivery team to ‘set it and forget it.’ They love that they can customize all features and directives and execute dynamic configurations, gain insight on auto back-off mode, while modifying queues without downtime. And they appreciate that Port25 Solutions is acutely involved with the latest industry standards, releasing new features and updates as the standards change.”

Listrak decided to collaborate exclusively with Port25 Solutions’ technical support staff to implement a solution that would scale effortlessly, in pace with the company’s present and future growth. The majority of Listrak clients are now on a dedicated VMTA, with roughly 15% of its customers on a shared pool.

Listrak’s decade-long success with PowerMTA™ gives the company confidence that it can continue to deliver unmatched dependability in the digital messaging infrastructure space. You can download the full case study here!
