Collectively, Message Systems customers move over 3 trillion messages a year — more than 25 percent of the world's legitimate email. These companies choose Message Systems because our solutions outperform any cloud or on premises alternative, providing the flexibility, deliverability and control they need to drive the highest possible customer engagement for their business – regardless of how big or small they may be.

With our four offerings, there’s an email infrastructure solution that’s right for you:

SparkPost is an email infrastructure service for developers who need to easily and quickly incorporate email into their applications. It is generally for smaller businesses with monthly volumes up to ~20 million messages a month and who want pay-per-use pricing. Medium-to-large-sized businesses who prefer an on-premise solution can take advantage of Port25’s low-cost and easy-to-use PowerMTA technology.

SparkPost Elite and Momentum are for businesses already delivering more than 20 million emails a month and who need a dedicated system, with complete control and customization capabilities. SparkPost Elite is for companies who want all the benefits of a dedicated world-class email infrastructure, but need a service hosted for them in the cloud; while Momentum is that same email infrastructure installed on-premises, for those companies that need to own their own software.

SparkPost Elite for Marketers is the world’s most powerful dedicated email service for one-to-one data-driven and contextually aware email marketing. It gives you complete control over your sending capabilities and reputation, while freeing you from the hassle of managing in-house servers and other hardware. All while lowering costs with pricing based on annual volumes, not CPM.

All of our solutions offer unparalleled performance. And because many of Message Systems solutions use common APIs, it is easy to switch from one to another as your business grows and your needs change.

With the SparkPost, SparkPost Elite, PowerMTA and Momentum options available, one of them is sure to fit your needs for either transactional or marketing emails; whether you are a big sender, or just becoming one.
