Toutapp is a tool that uses Twilio to send SMS and aims to make emailing more efficient by allowing users to quickly send e-mails via SMS while on-the-go, with an iPhone app and new features being continually added. The company's goal is to evolve email to improve communication productivity for businesses over the next 5 years. Toutapp was started as a weekend project and has grown into a brand-agnostic platform using a combination of Rails, Redis, Javascript frameworks, and other tools. The company values user experience and has worked closely with Twilio to develop its API, citing the platform's UX-focused approach as a key factor in their success. With new features and resources being added regularly, Toutapp is well-positioned to achieve its goal of becoming the defacto email client for businesses.
