With developer DNA at its core, SendGrid was founded in 2009 by 3 developers who set out to build a better way to send email. Together, they pioneered the transactional email category and today SendGrid is a leader in email infrastructure, having delivered nearly 600 billion emails to date. The founders still write code every day and SendGrid’s scale, expertise and resources continue to help make its customer-senders successful. SendGrid offers strong inbox delivery rates, best-in-class scalability, and the largest support and account management services team in the industry.

With the launch of Marketing Campaigns in December of 2015, SendGrid extended its customer communication platform. The new email marketing service empowers senders to deliver promotional emails that drive meaningful and lasting engagements, at a fraction of the cost of competitors. SendGrid enables customers to execute and scale both their marketing and transactional email campaigns on one single platform. Since the launch, 9,000 active Marketing Campaigns customers have collectively sent over 500 million emails.
