SendGrid is a top cloud-based email platform that effectively delivers over 18 billion of customer engagement emails every month for Internet and mobile-based companies such as Pinterest, Airbnb, Pandora, Spotify, Hubspot, Linkedin, Uber, and FourSquare, as well as traditional companies such as Walmart, Intuit, Taco Bell, and Costco. SendGrid has been established as an API company. It has been built to serve developers and makes it fast for companies to send an email regardless of their environment. It allows you to send an email over SMTP or HTTP, or if you want, even use one of the company's official client libraries. In a few minutes, your company can send your first email and more.

Picking a transactional email service for your app often means you'll end up using two email services: a simpler newsletter service to let your marketing team send updates, promotions and more, along with a transactional email service to send your app's messages. It doesn't have to be that way, though. SendGrid, which lists itself as the largest email infrastructure as a service provider, gives you both a transactional email service and an email marketing platform all in one.

SendGrid's transactional service isn't simply an SMTP server bolted onto a marketing platform; it's a serious email sending tool that's used by hundreds of thousands of companies. Its API is designed to make sending emails simple, and you can integrate it with your app easily using its code libraries. There's APIs for sending emails, along with an event API to get notifications and stats about your emails automatically, and a parse API to grab the contents of replies and other emails you receive and use them inside your app. You'll find the tech in SendGrid that you need to make sure your emails always get delivered, with custom email authentication certificates, integration with ISP feedback loops to know when your messages are marked as spam, and IP address reputation scoring so you'll know how likely your messages are to be marked as spam. And, you'll get detailed analytics and reports, and the option to download the data and look through it on your own. SendGrid virtually eliminates the complexities that usually go along with sending corporate emails on a large scale. SendGrid improves deliverability for your application-generated email.

SendGrid has a highly qualified team who are focused on nothing else but email deliverability and compliance. Also, SendGrid delivers a huge volume of email effectively. The app sends 4,190 emails per second. SendGrid has sent over 400 billion emails to date. To put that in perspective, that's more emails than there are stars in the Milky Way, or more emails daily than Twitter sends tweets.
