“When we needed to scale, it just worked. Mailgun helps us focus on product innovation instead of worrying about email infrastructure…[Sinch] understands our unique needs as a Taiwan-based company and has been proactive with guidance and support.“
C.T. Yeh CEO of NewsLeopard

NewsLeopard, a Taiwan-based email marketing platform, makes digital campaigns simple and effective for small and mid-sized businesses. Since its launch over a decade ago, the company has empowered thousands of marketers to reach their audiences through email, SMS, and landing pages, all from an intuitive platform. 

Today, the company supports over 15,000 customers and sends hundreds of millions of emails each year. Its infrastructure can deliver over 10,000 emails per minute while maintaining 99% system reliability, setting it apart as one of Taiwan’s leading providers in the email marketing space. 

“Our no-code, drag-and-drop tools, and virtual automation make it easy for non-technical marketers to do everything from collecting leads, to sending campaigns, to tracking results,” said C.T. Yeh, CEO of NewsLeopard. “And with reliable email infrastructure and strong deliverability practices working behind the scenes, the whole experience is fast, smooth, and easy for any team to use.” 

Their success with email marketing is all thanks to a partnership they made before their platform even launched. 

Building speed, scalability, and reliability

NewsLeopard’s launch came with some serious pressure. 

As a fledgling enterprise, they faced several challenges. Time to market was critical. To get a professional email marketing platform into their customers’ hands in a timely manner, they couldn’t spend months building complex infrastructure from scratch.  

Speed wasn’t their only constraint – limited resources meant every dollar had to count, making cost efficiency critical for a growing startup. And once they were up and running, scalability was just as important. The team needed to build for growth without compromising the deliverability they promised their customers. 

From day one, they knew the best solution was Sinch Mailgun for a proven, scalable email foundation. Mailgun’s APIs gave NewsLeopard the performance and control it needed right away.  

“Dedicated IPs and reputation management give us full control over how we send emails and proactive monitoring via webhooks, so we get an alert right away,” C.T. shared. 

Mailgun’s email reputation services also helps them keep lists clean and bounce rates low, which protects their sender reputation and improves ROI for their customers. 

Results that drive long-term growth

The right technical foundation helped NewsLeopard move fast and grow sustainably. They couldn’t afford to make mistakes at the start.  

C.T. explained, “If we moved too slowly, we would miss the market window. If deliverability was late, our clients’ campaigns wouldn’t land, and they wouldn’t stick around. If we couldn’t handle volume, we couldn’t onboard more clients, which cut our growth. So, choosing the right tech partner was critical, and we got the code right from the start.” 

Working with Sinch Mailgun proved to be an early decision that paid off. One of Taiwan’s largest retailers now sends more than 100 million emails per year through NewsLeopard’s platform. Across all their customers, the company now delivers over 30 million emails every month, with a 99% delivery success rate.

A partnership that scales with success

What began as a search for the right email infrastructure has grown into a trusted partnership. 

“When we needed to scale, it just worked,” C.T. said. “Mailgun helps us focus on product innovation instead of worrying about email infrastructure…[Sinch] understands our unique needs as a Taiwan-based company and has been proactive with guidance and support.” 

With Sinch powering the technical backbone, NewsLeopard can focus on what it does best — helping businesses communicate, connect, and grow through better email marketing.
