The challenge
Industrial-strength infrastructure for messaging around the clock.
Ranked #6 in Inc. 500's Top 100 Advertising and Marketing companies, Sailthru improves customer engagement and retention with today's leading ecommerce and media brands. It is an omnichannel marketing technology company with an international client base, deploying hundreds of millions of automated outbound messages daily.
Prior to selecting PowerMTA, Sailthru ran on an open source solution, Postfix. While most US-based ESPs and marketing automation technologies experience a digital messaging rush in the morning and early afternoon, Sailthru personalizes delivery time for each individual user based on when they are most likely to open email and convert. That results in high volumes of messages sent around the clock, so Sailthru demanded industrial-strength messaging infrastructure that would manage its rising email volume and, above all, required stability and dependability in its deliverability platform.
- Volume. The ability to manage large volumes of email traffic.
- Queue management. Capacity to transfer messages from queue to queue under heavy volume.
- Stability and scale. Legendary stability at a reasonable price point, with the ability to maintain large clusters of servers effortlessly — plus ease of configuration and customized deliverability data.
The solution
Real-time queues and configuration built for peak traffic.
By selecting PowerMTA, Sailthru radically enhanced its messaging performance and dependability, focusing on the ease of configuration and traffic management patterns. PowerMTA impressed Sailthru with its ability to view queues in real-time, and the flexibility to transfer messages from queue to queue under heavy volume, while load times rapidly diminished.
Another important feature was the responsiveness of the reporting interface during peak times — it would load immediately and give Sailthru direct views into the responses from the receivers. Tracking campaigns by JOBID also improved visibility into their client stream. Sailthru closely analyzed the two leading commercial offerings in the space and, after thorough review and evaluation, selected PowerMTA as its mission-critical email delivery solution: ease of use, performance and legendary stability, a rich feature set, and a reasonable price point made it a sound investment for their sending environment.
“PowerMTA has provided Sailthru with a rock solid application that we can push to the limits — and we never have to worry about missing a beat.”
Ken Pfeiffer, Director of Global Delivery, Sailthru
