About SendGrid

Founded in 2009, after graduating from the TechStars program, SendGrid has developed a cloud based service that solves the challenge of email delivery by delivering emails on behalf of companies. SendGrid eliminates the complexity of sending email, saving time and money, while providing reliable delivery to the inbox. With over a decade of thought-leadership backed by a stellar record of delivering email, SendGrid is climbing to new heights. Over 150,000 customers use SendGrid's email cloud infrastructure, analytics, and support as an alternative to self-managed MTA software to reliably deliver over 10 billion emails a month at scale for web and mobile apps. The SendGrid API SDK for Windows allows you to easily integrate SendGrid's email APIs with Microsoft technologies.
