About Message Bus

Message Bus, founded in 2010 by a team that includes Twitter co-founder Jeremy LaTrasse, was established to address the complexities of large-scale email delivery. LaTrasse, who previously served as Twitter's director of operations, leveraged his experience in scaling cloud-based platforms to tackle the persistent challenges of email messaging, a significant hurdle he encountered at the social media giant. The company later brought on Paul Midgen, the former director of email delivery and anti-spam at Hotmail, to serve as its CEO.

Read full description

The firm operates as a cloud-native messaging service provider, focusing on ensuring that high volumes of legitimate emails—be they critical, transactional, or promotional—successfully reach their intended inboxes rather than being filtered into spam folders. Message Bus offers a solution for businesses that struggled with low engagement and delivery problems when using in-house or other cloud-based email services. The platform is engineered to handle the technical intricacies of email deliverability, allowing clients to focus on the content of their messages.

The service is built as a cloud-native application, meaning it isn't tied to a single cloud provider's infrastructure and can be deployed across multiple services like Amazon Web Services and Rackspace. This architecture provides scalability and resilience. Key features of the platform include traffic segmentation, automated reputation management, real-time analytics, and in-depth placement analysis. The business model is subscription-based, with pricing determined by the volume of emails a client sends, catering to a range of customers from those sending a million messages a month to those sending tens of millions. By integrating with Message Bus, companies could offload the need for dedicated messaging hardware and personnel, reducing both infrastructure costs and operational complexity.
